on the probe cable or exposing it to sharp bends. Touching a broken cable during
measurements can cause injuries.
●
Set up all probe connections to the instrument before applying power.
Working with hazardous voltages
Voltages higher than 30 V RMS, or 42 V peak, or 60 V DC are regarded as hazardous
contact voltages. Direct contact with them can cause serious injuries.
Make sure that only electrically skilled persons use the products for measurements on
hazardous contact voltages. These working conditions require special education and
experience to perceive risks and to avoid hazards which electricity can create.
When working with hazardous contact voltages, use protective measures to preclude
direct contact with the measurement setup:
●
Do not touch exposed connections and components when power is applied.
●
Switch off the test circuit while connecting and disconnecting probe leads.
●
Use only insulated voltage probes, test leads and adapters.
●
Make sure that the input leads fulfill the safety requirements for your measurement.
The delivered input leads might have a jacket wear indicator that indicates a worn
jacket by different jacket color. In this case, do not use the input lead. Replace it
with a new one.
●
When connecting to the DUT, keep your fingers behind finger guard. Remove jew-
elry, watches, and other metallic objects. Only use 4 mm safety banana plugs.

●
Do not attach the clamp to bare unisolated conductors. To avoid injury from a short
circuit, measure at a location on an insulated wire where the insulation is sufficient
for the circuit voltage.
●
Connect the probe only to the secondary side of a breaker. With this measure, you
avoid injury, if a short circuit occurs.
●
The following effects can cause burns and fire or damage to the measurement site:
– Eddy current loss can cause heating of the sensor head.
– Dielectric heating can cause heating of cord insulation and other materials.
●
When measuring current that includes a high-frequency component, consider the
derating characteristics of the probe. Do not measure any current that exceeds the
rated current.
●
Using the probes with high frequencies or strong magnetic fields may cause the
device to become abnormally hot, resulting in fire, equipment damage, or burns.
Measurement categories
IEC 61010-2-030 defines measurement categories that rate instruments on their ability
to resist short transient overvoltages that occur in addition to the working voltage. Use
the measurement setup only in electrical environments for which they are rated.
●
0 - Instruments without rated measurement category
For measurements performed on circuits not directly connected to mains, for exam-
ple, electronics, circuits powered by batteries, and specially protected secondary
circuits. This measurement category is also known as CAT I.
●
CAT II:
For measurements performed on circuits directly connected to the low-voltage
installation by a standard socket outlet, for example, household appliances and
portable tools.
●
CAT III:
For measurements performed in the building installation, such as junction boxes,
circuit breakers, distribution boards, and equipment with permanent connection to
the fixed installation.

Using the touchscreen allows for direct interaction with the instrument. Use your
finger to place waveforms on the screen, mark areas for zoom, set parameters in
dialogs, enter data, and much more. The control elements and actions on the
screen are based on common concepts, and you easily become familiar with the
user interface.
Tapping the screen works like clicking mouse buttons:
– Tap = click: Selects a waveform or parameter, or provokes an action.
– Double-tap = double-click: Has the same effect as touch and hold, it opens the
on-screen keyboard or keypad, or a specific editor if available.
●
Function keys and rotary knobs:
The front panel provides frequently used functions and controls to operate the
instrument. Use knobs to set levels and scales, and keys to initiate actions and to
open dialogs.

4.4 Working with waveforms
The R&S MXO 5 can create and display many waveform types. The most important
are:
●
Channel waveforms:
For each input channel, one channel waveform is shown.
●
Reference waveforms:
Four waveforms can be used as reference for comparison and analysis.
●
Math waveforms:
Five mathematic waveforms can be created with mathematic operations performed
on channel, reference, and other math waveforms.
●
Zoom waveforms:
Show the details of waveforms.
●
Digital waveforms:
The Mixed Signal Option R&S MXO5-B1 provides 16 digital channels grouped in
two logic probes (pods) with 8 channels each.
Waveform handling
The R&S MXO 5 can show and analyze many waveforms. To handle this multitude
while keeping track of it, the R&S MXO 5 provides intelligent support:
●
The color system helps to distinguish the waveforms. The color of the vertical
rotary knobs indicates the signal that is focused (selected). The color of each
waveform can be changed, the color of its signal icon and of the illuminated keys is
adjusted to the new color. Alternatively, a color table can be assigned to a wave-
form.
Settings: "Menu" > "Settings" > "Appearance" > "Colors" tab.
●
You can arrange the waveforms in one diagram, or in separate diagrams. The
Rohde & Schwarz SmartGrid function helps to arrange the waveforms.

Waveform states
Depending on its place on the screen and the effect of settings, a waveform has one of
the following states:
●
Off
●
Active:
The waveform is shown in a diagram
●
Selected:
One of the active waveforms that has the focus. In each diagram, one of the
assigned waveforms is selected – it appears "on top" in the diagram, and the grid
labels have the color of the selected waveform.
The vertical [Position] and the [Scale] knobs are illuminated with the color of the
selected waveform.
●
Minimized:
The waveform signal icon is greyed out, and the waveform is removed from the
diagram.
To switch a waveform on
A channel waveform is activated when you connect the probe. You can switch it on and
off according to your needs.
► Choose one of the following ways:
● Press the channel key.
● In the "Vertical" dialog box, select the channel. Tap "Show channel" > "On".
The waveform is now active, selected, and is shown in the diagram.
Remote command: CHANnel<ch>:STATe on page 464
To select a waveform
► Choose one of the following ways:
● Tap the waveform in the waveform diagram.
● Tap the signal icon.
● To select a channel, reference, or math waveform, press the corresponding
key.

6 Acquisition and waveform setup
6.1 Horizontal setup
The "Horizontal" dialog provides the time base configuration for channel and spectrum
waveforms.
6.1.1 About the horizontal system
Horizontal settings, also known as timebase settings, adjust the waveforms in horizon-
tal direction.
Typically, the trigger is the determining point of the waveform record. In many scenar-
ios, you want to analyze the waveform some time before or after the trigger. To adjust
the horizontal acquisition window to the waveform section of interest, you can use the
following parameters:
●
The horizontal position defines the time distance of the trigger point (the zero
point of the diagram) to the reference point. Changing the horizontal position, you
can move the trigger point, even outside the screen.
●
The reference point is the rescaling center of the time scale on the screen. If you
modify the time scale, the reference point remains fixed on the screen, and the
scale is stretched or compressed to both sides of the reference point.
Unlike vertical settings, which are waveform-specific, the horizontal settings apply to all
active waveforms.
Timebase settings are interdependent:
Timebase range = Time scale * Number of divisions
Horizontal setup
Acquisition and waveform setup
R&S
®
MXO 5 Series
101User Manual 1802.3369.02 ─ 02
The number of divisions is 10, which is the only constant parameter.
6.1.2 Horizontal Setup settings
Access: "Menu" > "Horizontal" > "Setup" tab, or tap the "Horizontal" label above the
diagram.
Time scale
Sets the horizontal scale, the time per division, for all waveforms in the time domain,
for example, channel and math waveforms.
Increase the scale to see a longer time interval of the waveform. Decrease the scale to
see it in more detail. The scale has a point that remains fixed on the screen when the
scale value is changing: the reference point.
Remote command:
TIMebase:SCALe on page 461
Timebase range
Sets the time of one acquisition, which is the time across the 10 divisions of the dia-
gram: Acquisition time = Time scale * 10 divisions.
Changing the acquisition time changes the time scale, too.
For long timebases, the acquisition progress is shown in the acquisition label, see
"Progress information" on page 66.
Remote command:
TIMebase:RANGe on page 461
Position
Defines the time distance between the reference point and the trigger point, which is
the zero point of the diagram. The horizontal position is also known as trigger offset.

If you want to see a section of the waveform some time before or after the trigger, enter
this time as horizontal position. The requested waveform section is shown around the
reference point. Use positive values to see waveform sections after the trigger - the
waveform and the diagram origin move to the left.
Remote command:
TIMebase:HORizontal:POSition on page 462
Reference point
Sets the position of the reference point in % of the screen. It defines which part of the
waveform is shown.
The reference point marks the rescaling center of the time scale on the screen. If you
modify the time scale, the reference point remains fixed on the screen, and the scale is
stretched or compressed to both sides of the reference point. If the "Position" is 0, the
trigger point is on the reference point.
The reference point is not marked in the diagram.

Mode
Selects, if the roll mode is set automatically by the instrument or if it is turned off.
In roll mode, the instrument shows the waveforms immediately, without waiting for the
complete acquisition of the waveform record. If the time base is slow - at long time
scale values - the roll mode saves waiting for the waveform display. The instrument
displays newly acquired waveform points at the right edge of the display and moves
the waveform to the left.
The roll mode has following restrictions:
●
Roll mode disables persistence
●
Event actions are not possible
The instrument activates the roll mode automatically if the following conditions are ful-
filled:
●
"Timebase range" exceeds the defined "Start roll time"
●
The "Acquisition mode" is set to "Sample" or "Peak detect"
●
"N-single/Avg count" = 1
●
Fast segmentation is disabled
●
Event actions are disabled
●
All serial buses are disabled
Measurement statistics evaluate the currently displayed waveform. Therefore, "Mea-
sure all events" is enabled automatically in roll mode.

6.1.5 Reference clock
Access: "Menu" > "Horizontal" > "Setup" tab > "Ref Clock"
The oven-controlled crystal oscillator (OCXO) produces a 10 MHz internal reference
signal with precise and stable frequency. You can output this clock signal for synchroni-
zation of other instruments. Conversely, you can also use an external 10 MHz refer-
ence signal. The input and output connectors for reference signals are on the rear
panel of the instrument.

Enables the use of an external 10 MHz reference signal instead of the internal refer-
ence clock.
Remote command:

6.2.1 About the acquisition system
Sampling and processing
The A/D converter samples the continuous signal under test at specific points in time
and captures digital values. The converter is working at a constant rate specified in
GHz.
The captured values are processed according to the acquisition settings. The result is
a waveform record that contains waveform samples and is stored in the waveform
memory. The waveform samples are displayed on the screen and build up the wave-
form.
The number of waveform samples in one waveform record is called record length.
The rate of recording waveform samples - the number of waveform samples per sec-
ond - is the sample rate. The higher the sample rate, the better the resolution is and
the more details of the waveform are visible.
Sample rate = 1 / Resolution
The sample rate can be the same as the constant rate of the A/D converter, or higher,
or lower. To get a higher sample rate, interpolation is used. Several interpolation meth-
ods are available. Other processing methods reduce the sample rate, or build the
resulting waveform from several consecutive acquisitions of the signal. These methods
are called acquisition modes.
Minimum sample rate and aliasing
A sufficient resolution is essential for correct reconstruction of the waveform. If the sig-
nal is undersampled, aliasing occurs - a false waveform is displayed. To avoid aliasing
and accurately reconstruct a signal, the sample rate must be at least 3 to 5 times the
fastest frequency component of the signal. A higher sample rate increases signal fidel-
ity, increases the chance to capture glitches and other signal anomalies, and improves
the zoom-in capabilities.
Interleaving
The R&S MXO 5 with 8 channels achieves its highest sample rate of 5 Gsample/s by
interleaving channels by twos. Interleaving assumes that only one of the paired chan-
nels is used. If the second channel of a pair is used (on display, or as trigger source,
math source, or measurement source), the interleaving mode is disabled. Without
interleaving, the channels work with 2.5 Gsample/s and reduced bandwidth.

The sample rate considers the samples of the ADC, and the processing of the cap-
tured samples including interpolation.

N-single/Avg count
The acquisition and average count has several effects:
●
It sets the number of waveforms acquired with [Single].
●
It defines the number of waveforms used to calculate the average waveform.
Thus, the instrument acquires sufficient waveforms to calculate the correct average
if "Average" is enabled for waveform arithmetic. The higher the value is, the better
the noise is reduced.
●
It sets the number of acquisitions to be acquired in a fast segmentation acquisition
series, and in the history.
The setting is read-only if "Segmented" > "Acquire maximum" is "On". See also

Acquisition mode
Sets how the waveform is built from the captured samples.
"Sample"
Usually, most signals are displayed optimally with this acquisition
mode but very short glitches can remain undiscovered by this
method.
"Peak detect"
The minimum and the maximum of n samples are recorded as wave-
form points, the other samples are discarded. Thus the instrument
can detect fast signal peaks at slow time scale settings that would be
missed with other acquisition modes.
"Envelope"
Each acquisition is done in sample mode, and the minimum and max-
imum values over some consecutive acquisitions build the envelope.
"Average"
The average is calculated from the data of the current acquisition and
a specific number of consecutive acquisitions before. The method
reduces random noise. It requires a stable, triggered and repetitive
signal.
The number of acquisitions for average calculation is defined with N-
single/Avg count.
If the waveform is clipped, the instrument shows a distorted average
waveform to indicate the clipping. Adjust the vertical scale to avoid
the clipping. The acquisition progress is shown in the acquisition

"Sample/Hold"
The ADC sample points are displayed like a histogram. For each
sample interval, the voltage is taken from the sample point and con-

Max available
Shows the maximum number of segments that can be captured with current sample

6.2.4 High definition mode
The high definition mode increases the numeric resolution of the waveform signal by
using digital filtering, leading to reduced noise. The higher vertical resolution reduces
quantization noise and acquires waveforms of higher accuracy with finer details of the
signal to be seen. The high definition is also applied to the digital trigger, thus the
R&S MXO 5 can trigger with the same high resolution with which they can display sig-
nals.
The maximum numeric resolution in high definition mode is 18 bit. The actual value
depends on the selected bandwidth. Increasing the bandwidth reduces the resulting
digital resolution. For dependencies and details, refer to the R&S MXO 5 specifica-
tions.
The number of vertical resolution bits defines the number of vertical levels that the
acquisition samples are mapped to (quantization). For example, 16 bits of resolution
represent 65536 voltage quantization levels, while 8 bits of resolution represent only
256 voltage levels. The waveform values are recorded with a word length of 16 bit,
except for peak detect decimation.

There are several ways to adjust vertical settings:
●
Use the keys and knobs in the Vertical functional block of the front panel to select
the channel, to scale the waveform, and to set the position or offset.
See Chapter 3.2.4.4, "Vertical controls", on page 37.
●

channel waveform.
●

6.3.1 About the vertical system
The controls and parameters of the vertical system are used to scale and position the
waveform vertically.
Vertical scale and resolution
Vertical scale and vertical position directly affect the resolution of the waveform ampli-
tude. The vertical scale corresponds to the ADC input range. To get the full resolution
of the ADC, set up the waveforms to cover most of the height of the diagram.
With an R&S MXO 5, you work with multiple diagrams, and each diagram obtains the
full vertical resolution, no matter where the diagram is placed. Therefore, use a sepa-
rate diagram for each waveform instead of the traditional setup that arranges the wave-
forms side by side in one diagram.
Bandwidth
For analog applications, the highest signal frequency determines the required oscillo-
scope bandwidth. The oscilloscope bandwidth should be higher than the maximum fre-
quency included in the analog test signal to measure the amplitude with very little mea-
surement error. To avoid aliasing, the oscilloscope bandwidth should be at least 3
times higher than the maximum frequency included in the signal.
Most test signals are more complex than a simple sine wave and include several spec-
tral components. A digital signal, for example, is built up of several odd harmonics. For
digital signals, the oscilloscope bandwidth should be at least 5 times higher than the
clock frequency to be measured.
The oscilloscope is not a stand-alone system. You need a probe to measure the signal
of interest, and the probe has a limited bandwidth, too. The combination of oscillo-
scope and probe creates a system bandwidth. To reduce the effect of the probe on the
system bandwidth, the probe bandwidth should exceed the bandwidth of the oscillo-
scope, the recommended factor is 1.5 x oscilloscope bandwidth.

To set the offset automatically, use [Autoset]. The current value is shown in the signal

Use the offset to measure small AC voltages that are overlaid by higher DC voltages.
Unlike AC coupling, the DC part of the signal is not lost with offset setting.
If an active probe is connected, the offset limit is defined by the probe. Refer to the
documentation of the probe for allowed values.
If a Rohde & Schwarz differential probe is connected, set the common-mode offset to
compensate for a common DC voltage applied to both input sockets (referenced to the
ground socket). Thus, you can measure on differential signals with high common mode
levels. You can measure the common mode input voltage using the R&S ProbeMeter.

With R&S MXO 5 oscilloscopes, you can use various probe types. Mostly these probes
are passive and active voltage probes. The instrument can detect many probes and
read out the probe-specific parameters, for example, bandwidth and attenuation.
You find all settings that are relevant for the connected probe in the "Vertical" > "Probe"
tab. The settings on the "Probe" tab change according to the type of the attached
probe. Probes with Rohde & Schwarz probe interface (probe box), and also many
other passive voltage probes, are recognized by the instrument. The R&S MXO 5
reads out the main characteristics of the probe and displays them. Other probes can-
not be detected, but their characteristics are known to the instrument. These known
probes are called "Predefined probes". Probes that are not recognized automatically
and not predefined are unknown probes, they require manual setting of measurement
unit and attenuation.

AutoZero, Use AutoZero
Differences in DUT and oscilloscope ground levels can cause larger zero errors, which
affect the waveform. If the DUT is ground-referenced, the AutoZero function corrects
the zero error of the probe to optimize measurement results at small signal levels. The
validation limit depends on the probe attenuation because probes with high attenuation
often have to compensate high offsets. AutoZero detects offset values even when the
signal is out of the current measurement range.
To correct the zero error of voltage probes, short the signal pin and the ground pin
together and connect them to the ground of the DUT. Then tap "AutoZero". While the
alignment is running, the instrument switches to DC coupling to display the waveform
correctly.
To include the measured offset in measurement results, enable "Use AutoZero".
If a current probe is connected, the function demagnetizes the probe's sensor head
and sets the waveform to zero position.

To set the waveform to zero level by the instrument, use "AutoZero". The detected
value is displayed.
Alternatively, you can adjust the value manually until the waveform is set to zero level.
Make sure to demagnetize the probe before zero adjustment.
The value is given in percent of the maximum range, which is internally defined. The
actual setup range depends on the temperature drift, the measured current and other
variables, and it can change over time. If you measure high currents, the probe core
magnetizes, which impairs the measurement results. Therefore, repeat "AutoZero"
before the measurement.

6.4.6 Adjusting passive probes
When using a passive probe, you have to compensate it when you connect it to the
instrument the first time. Compensation matches the probe cable capacitance to the
oscilloscope input capacitance to assure good amplitude accuracy from DC to upper
bandwidth limit frequencies. A poorly compensated probe reduces the performance of
the probe-oscilloscope system and introduces measurement errors resulting in distor-
ted waveforms and inaccurate results.
Two connector pins are located on the front panel. The pin is on ground level. The
pin supplies a square wave signal with 1 kHz for low frequency probe compensa-
tion.
1. Connect the BNC connector of the probe to one of the channel inputs.
2. Connect the probe's ground connector to the ground compensation pin, and the
probe tip to the signal pin.
3. Press [Autoset].

7.1 Basics of triggering
Triggering means to capture the interesting part of the relevant waveforms, and the
trigger point is the determining point in the waveform record. Choosing the right trigger
type and configuring all trigger settings correctly allows you to detect various incidents
in analog, digital, and protocol signals.
How the instrument triggers
A trigger occurs if the complete set of trigger conditions is fulfilled. The instrument
acquires continuously and keeps the sample points to fill the pre-trigger part of the
waveform record. When the trigger occurs, the instrument continues acquisition until
the post-trigger part of the waveform record is filled. Then it stops acquiring and waits
for the next trigger. When a trigger is recognized, the instrument does not accept
another trigger until the acquisition is complete and the holdoff time has expired.
Trigger setup
A simple trigger setup includes:
●
Source of the trigger signal
●
Trigger type selection and setup
●
Horizontal position of the trigger, see: Chapter 6.1.1, "About the horizontal system",
on page 100
●
Trigger mode
The R&S MXO 5 provides various trigger types for troubleshooting and signal analysis,
for example, edge trigger, glitch trigger, interval trigger, and much more.
For complex tasks like verifying and debugging designs, advanced trigger settings are
available:
●
Filter to remove high or low frequencies from the trigger signal
●
Hysteresis to avoid unwanted trigger events caused by noise
●
Holdoff to define exactly which trigger event causes the trigger
Action on trigger

R&S

MXO 5 Series
153User Manual 1802.3369.02 ─ 02
Holdoff conditions define a waiting time after the current trigger until the next trigger
can be recognized.
Trigger mode
Sets the trigger mode which determines the behavior of the instrument if no trigger
occurs. The current setting is shown on the trigger label.
To toggle quickly between "Auto" and "Normal" mode, use the [Auto Norm] key on the
front panel (in "Trigger" section).
"Auto"
The instrument triggers repeatedly after a time interval if the trigger
conditions are not fulfilled. If a real trigger occurs, it takes prece-
dence. This mode helps to see the waveform even before the trigger
conditions are set correctly. The waveform on the screen is not
synchronized, and successive waveforms are not triggered at the
same point of the waveform. The time interval depends on the time
base settings.
"Normal"
The instrument acquires a waveform only if a trigger occurs, that is, if
all trigger conditions are fulfilled. If no trigger occurs, no waveform is
acquired and the last acquired waveform is displayed. If no waveform
was captured before, none is displayed.
When no trigger has been found for longer than one second, a mes-
sage box appears that shows the time elapsed since the last trigger.
"Free run"
The instrument starts acquisition immediately and triggers after a
short time interval independent of the time base settings and faster
than in "Auto" mode. Real triggers are ignored. Use this mode if the
"Auto" mode is too slow.

Force trigger
Provokes an immediate single acquisition. Force the trigger if the acquisition is running
in normal mode and no valid trigger occurs. Thus, you can confirm that a signal is
available and use the waveform display to determine how to trigger on it.
Remote command:
TRIGger:FORCe on page 510
Holdoff mode
Selects the method to define the holdoff condition.
The trigger holdoff defines when the next trigger after the current will be recognized.
Thus, it affects the next trigger to occur after the current one. Holdoff helps to obtain
stable triggering when the oscilloscope is triggering on undesired events.
Holdoff settings are not available if the trigger source is an external trigger input or
serial bus, and if you trigger on a sequence of events.
Example:
For example, you want to analyze the first pulse in a burst of several pulses. At first,
you select a sufficiently slow time base to display the entire burst. Then, you set the
holdoff time a little longer than the length of the burst. Now, each trigger corresponds to
the first pulse in successive bursts, and you can change the time base to display the
waveform in more detail.
The following methods are available:
"Time"
Defines the holdoff directly as a time period. The next trigger occurs
only after the "Holdoff time" has passed.
"Events"
Defines the holdoff as a number of trigger events. The next trigger
only occurs when this number of events is reached. The number of
triggers to be skipped is defined in "Holdoff events".
"Random"
Defines the holdoff as a random time limited by "Minimum time" and
"Maximum time". For each acquisition cycle, the instrument selects a
new random holdoff time from the specified range.
Random holdoff prevents synchronization to discover effects invisible
with synchronized triggering, for example, the features of a pulse
train.
"Auto"
The holdoff time is calculated automatically based on the current hori-
zontal scale.
"Auto time scaling" defines the factor that the horizontal scale is multi-
plied with.
"Auto time" shows the resulting holdoff time: Auto time = Auto time
scaling * Horizontal scale.
"Off"
No holdoff

8.1.2 Zooming for details
To define the zoom area on the touchscreen
For graphical zooming, you use your finger on the screen.
1. On the toolbar, tap the "Add zoom" icon.
The zoom overlay menu opens.
2. Draw a rectangle in the diagram that defines the zoomed area.
While you drag your finger on the touchscreen, a dotted rectangle indicates the
current zoom area.
The indicated area is magnified in a new zoom diagram. The original diagram
shows the zoom area as a rectangle.
3. If the position of the zoom area is not correct, drag the rectangle in the overview to
the correct position.
4. If the size of the zoom area is not yet ideal, tap the rectangle in the overview dia-
gram.
Now, 4 white lines indicate the edges of the zoom area. A dashed white line indi-
cates the selected edge, which you can adjust.
5. Touch the edge that you want to move. Drag it to the required position.
To create a zoom using the zoom dialog box
► If you want to create a new, unconfigured zoom, tap the "Add" icon.

8.2 Mathematics
Math waveforms are calculated waveforms. You can define up to 8 math waveforms
and display them on the screen, and use it as source for further analysis.
It is calculated out of one or two analog channels, or another math waveform using
several predefined operations. You can define up to 5 equations. The complete config-
uration is called equation set and can be saved for later use.
You can analyze math waveforms in the same way as channel waveforms: use zoom,
perform automatic and cursor measurements, and save as reference waveform.
You can store a math waveform as a reference waveform and restore it later.

8.2.3 Math filter
Access:[Math] > "Filter" tab
The finite impulse response filter is a filter to create filtered math waveforms with low-
pass or highpass. The filter requires additional settings.
In remote control, filter settings are defined in the expression string, see CALCulate:

Type
Selects, if the filter is highpass or lowpass.
Source 1
Selects the input channel of the signal.
Cut-off
Sets the limit frequency for the filter.
Cutoff frequency for lowpass filter
The cutoff frequency depends on the horizontal resolution and the filter characteristics.
The frequency for the lowpass filter can only be set in this range:
f_g_3dB = (0.001 ... 0.2)* f_a_in for Gaussian FIR filter
f_g_3dB = (0,001 ... 0.4)* f_a_in for rectangular FIR filter
Where: f_g_3dB = cutoff frequency to be set for the lowpass filter, and f_a_in = recipro-
cal of the resolution, or sample rate.
Cutoff frequency for highpass filter
To check limit frequency for the highpass filter, convert it to an equivalent lowpass fre-
quency:
f_LP = f_a_in/2 - f_HP

8.3 History
The history accesses the data of previous acquisitions and provides them for further
analysis.
8.3.1 About history
If a continuous acquisition runs, the captured data is stored in the sample memory and
the current acquisition is processed and shown on the display. After the acquisition is
stopped, the history accesses the captured samples that were stored, displays these
samples as history waveforms, and makes them available for further analysis. It con-
siders all channels that were enabled during the running acquisition.
When a new acquisition is started with [Single], the memory is cleared and written
anew. In continuous acquisition, stopping and starting the acquisition does not clear
the memory, and the history memory is continued. When the memory is full, new
acquisitions are stored, and the oldest are removed (first in, first out). The history mem-
ory is cleared when the acquisition parameters are changed. To clear the history mem-
ory on demand, use the [Clear] key or the "Clear" tool on the toolbar.

The number of stored history waveforms depends on the memory size, the number of
enabled channels, and the record length. The shorter the record length, the less the
number of channels, and the larger the memory, the more history waveforms are
saved.

Enhancement mode
The enhancement mode is taken from the source waveform of the reference. The
enhancement mode is set automatically by the instrument and depends on the sample
rate. As long as the waveform sample rate is not higher than the ADC sample rate, the
instrument works automatically in real time mode (RT). At higher waveform sample
rates, the instrument changes to interpolated time mode (IT), where interpolation adds
waveform points between the captured ADC samples by various mathematical meth-
ods, see Interpolation.
Waveform arithmetic
The waveform arithmetic is taken from the source waveform of the reference, and it
cannot be changed for the reference. Waveform arithmetic builds the resulting wave-
form from several consecutive acquisitions of the signal. The arithmetic methods are
envelope and average, which are set in the Acquisition mode.

sors can be positioned manually, or can be configured to follow the waveform. You can
measure on one waveform, or on two different waveforms (sources).
Up to 4 cursor sets can be configured and displayed. Each cursor set consists of a pair
of horizontal or vertical cursors, or both. Cursor lines can be coupled so that the initially
defined distance is always maintained.
The cursors are displayed in the diagrams of the source waveform only, or in all dia-
grams. For each measurement, labels can be defined for the cursors. By default, the
cursors are labeled as Cu1.1 and Cu1.2.
How to set up cursor measurements is described in Chapter 9.1.2, "Using cursors",
on page 185. The Chapter 9.1.3, "Settings for cursor measurements", on page 187
provides a detailed description of all settings.
For details on using the result table, see Chapter 4.9, "Displaying results", on page 62.
9.1.1.1 Cursor measurements on time-based waveforms
The cursor for measurement on time-based waveforms returns the following results.
The results are displayed automatically when a cursor measurement is enabled.
Label Description
"X1, X2" Time at the position of the vertical cursors.
"Y1, Y2" Vertical values of the waveform at the position of the horizontal cursors in V or
A.
"dx" Difference between the vertical cursor (time) values

The mean value of the signal is determined. If the signal passes the mean value, an edge is coun-
ted. A positive pulse is counted if a rising edge and a following falling edge are detected. A nega-
tive pulse is counted if a falling edge and a following rising edge are detected.
Edge count EdCo The number of positive or negative edges, or of both positive and negative edges.
The instrument determines the mean value of the signal and counts an edge every time the signal
passes the mean value.

Setup/Hold time measurement
Setup/Hold measurements analyze the relative timing between two signals: a data sig-
nal and the synchronous clock signal. Setup time is the time that the data signal is
steady before clock edge - the time between a data transition and the next specified
clock edge. Hold time is the time that the data signal is steady after clock edge - the
time between a data transition and the previous specified clock edge.
"Setup/Hold time" measures and displays the setup and hold durations. "Setup/Hold
ratio" measurements return the ratio of the setup time to the sum of hold and setup
time: T

10 Spectrum analysis
The R&S MXO 5 provides an easy way to set up a spectrum analysis. The spectrum
settings are independent of the time domain settings but the time and frequency
domains are time-correlated.
10.1 Fundamentals of spectrum analysis
During spectrum analysis, a signal in the time domain is converted to a spectrum of
frequencies. As a result, either the magnitude or the phase of the determined frequen-
cies can be displayed. Spectrum analysis can be restricted to an extract of the original
time base, and the results display can be restricted to a specified frequency range.
t[s]
FFT
f[Hz]
Window functions
Each frame is multiplied with a specific window function after sampling in the time
domain. Windowing helps minimize the discontinuities at the end of the measured sig-
nal interval and thus reduces the effect of spectral leakage, increasing the frequency
resolution.
There are several window functions that can be used in FFT analysis. Each of the win-
dow functions has specific characteristics, including some advantages and some trade-
offs. Consider these characteristics carefully to find the optimum solution for the mea-
surement task.
For details, see "Window type" on page 224.
Gating functions
You can restrict the time base of the input signal for which spectrum analysis is to be
performed. You can define start and stop times for the time base extract.

Restricting the result range
You can restrict the results of the spectrum analysis to a specified frequency range.
The frequency range can be defined in two ways:
●
Define a center frequency and frequency span
●
Define start and stop frequencies
Dependencies between spectrum parameters
Spectrum analysis in the R&S MXO 5 is highly configurable. Several parameters,
including the resolution bandwidth, frequency span and center frequency, can be
defined according to your requirements. Note, however, that several parameters are
correlated and not all can be configured independently of the others.
The resolution bandwidth defines the minimum frequency separation at which the
individual components of a spectrum can be distinguished. Small values result in high
precision, as the distance between two distinguishable frequencies is small. Higher val-
ues decrease the precision, but increase measurement speed.
The minimum achievable RBW depends on the integration time which is equivalent to
the number of samples available for calculation. If a higher spectral resolution is
Fundamentals of spectrum analysis

R&S
®
MXO 5 Series
220User Manual 1802.3369.02 ─ 02
required, the number of samples must be increased by using a higher sample rate or
longer record length. To simplify operation, some parameters are coupled and auto-
matically calculated, such as record length and RBW.
The frequency span and center frequency define the start and stop frequency of the
spectral diagram. By default, a suitable frequency range according to the resolution
bandwidth is selected, in respect to performance and precision. Span and RBW set-
tings are coupled, so that the parameters can be adjusted automatically as necessary.
With a Span/RBW ratio of 100 and a screen resolution of 1000 pixels, each frequency
in the spectrum is displayed by 10 pixels. A span/RBW ratio of 1000 provides the high-
est resolution. For full flexibility, the span/RBW coupling can also be disabled. Note,
however, that a higher span/RBW ratio (i.e. low RBW values and large frequency
spans) result in large amounts of data and extend the duration of the calculation.
10.2 Configuring spectrum waveforms
During spectrum analysis, a signal in the time domain is converted to a spectrum of
frequencies. A basic spectrum waveform can be displayed quickly. By defining addi-
tional parameters, the waveform can be configured in more detail.
To display a basic spectrum waveform
1. Press the [FFT] key.
The "Setup" tab of the "Spectrum" dialog box opens.
2. Set the "Source" to the input signal.
3. Enable "Display".
4. If necessary, edit the spectrum waveform parameters as described in the following
procedures.

To configure the spectrum
By default, a suitable frequency range for the expected horizontal values according to
the resolution bandwidth is selected, in respect to performance and precision. Span
and RBW settings are coupled. If a more precise evaluation is required, for example for
postprocessing in a different application, disable the coupling and change the fre-
quency ranges and resolution bandwidth values as required.
1. Press [FFT].
The "Spectrum" dialog opens.
2. In the "Setup" tab, specify the frequency range you want to display using one of the
following methods:
● Select "CF span". Enter a "Center" and a "Span" that define the spectrum.
● Select "Start Stop". Enter a "Start" and "Stop" frequencies that define the spec-
trum.
● Tap the "Full span" button to display the complete spectrum resulting from the
FFT analysis.
3. Define the resolution bandwidth for the spectrum result.
The resolution bandwidth defines how precise the results are, i.e. how close
together the individual frequencies can be. Small values result in high precision, as
the distance between two distinguishable frequencies is small. Higher values
decrease the precision, but increase performance.
You can define the RBW manually, or couple it to other settings. Do one of the fol-
lowing:
● To couple the RBW to the span, enable "Auto RBW". Define the "Span/RBW"
ratio, the smaller the ratio, the higher the RBW becomes to display the same
frequency span.
● Disable "Auto RBW". Enter the "RBW" manually.
4. Tap "Advanced".
5. Select the most suitable "Window type" for your source data. Window functions are
multiplied with the input values and thus can improve the spectrum display. For
details, see "Window type" on page 224.
To restrict the input values (gating)
You can restrict the time range for which the FFT is calculated, resulting in a restricted
spectrum.
1. Open [FFT] > "Gate" tab.
2. Enter the "Start" and the "Stop" times that define the gate area.
3. Set the "Position" and the "Width".
The spectrum waveform displays the spectrum for the specified time span.

Traces
Spectrum analysis can only be performed on a maximum number of values at once. If
more values must be calculated, the input signal is divided into segments, each of
which is calculated separately. The segments need not to be disjunct. In this case, the
arithmetic mode defines how the final result is calculated from the individual results.
The following methods are available:
"Norm"
The data of only one segment is considered. In effect, no arithmetics
are processed.
"Min hold"
Determines the minimum result for each input value from the data of
the current acquisition and the acquisitions before.
"Max hold"

Peak excursion
Defines a relative threshold, the minimum level value by which the waveform must rise
by to be considered as a peak. For the peak to be considered, the excursion threshold
must be met both on the left and the right sides of the peak.
To avoid identifying noise peaks, enter a peak excursion value that is higher than the
noise levels.
This setting is only available for spectrum waveforms. It is valid for cursor measure-
ments, spectrum measurements and peak search.
Example:
In the figure below, 2 peaks are shown, that rise above the defined "Threshold". Peak 1
fulfills the defined "Peak excursion" value and is counted as a peak. Peak 2 does not
fulfill the defined "Peak excursion" value on the right and is not counted as a peak.

11.1 Frequency response analysis (option R&S MXO5-K36)
The frequency response analysis (FRA) option lets you perform low-frequency
response analysis on your oscilloscope. It characterizes the frequency response of a
variety of electronic devices, including passive filters and amplifier circuits. For
switched-mode power supplies, it measures the control loop response (CLR) and
power supply rejection ratio (PSRR).
The FRA option uses the oscilloscope’s built-in waveform generator to create stimulus
signals ranging from 10 Hz to 100 MHz. Measuring the ratio of the stimulus signal and
the output signal of the DUT at each test frequency, the oscilloscope plots gain and
phase logarithmically.
Having both time and frequency domain views allows you to monitor if the injected sig-
nal causes distortion that leads to errors in the measurement.

11.2.2.2 Power quality
In an electric circuit power is a measure for the rate of flow of energy at a certain point
of the circuit. The active power of a circuit, or the energy that can be used for work, is
the portion of energy that is transferred in one direction over a complete cycle of the
AC waveform. In AC circuits, however, inductive and capacitive elements can store
energy temporarily. This portion of the power flow known as reactive power is then
returned to the source without doing any work.
The power quality analysis measurements include the active power, the reactive
power, the apparent power and the power factor. The crest factors and the phase angle
between the current and voltage are also measured. These properties describe the
power transfer in the system and allow you to characterize the power quality of the sys-
tem.
Required probes:
●
Differential voltage probe
●
Current probe
Configuring power quality
For details of the configuration settings, see "Power quality settings" on page 251.

11.2.2.3 Power harmonic
Current harmonics appear in an electric power system due to nonlinear electric loads.
The harmonics can be ejected back into the AC line and disturb other equipment on
the grid. To avoid this disturbance, there are often standards of compliance that con-
sumer or industry end-products must meet.
The "Harmonics" analysis tests the devices according to the precompliance standards
EN 61000-3-2, MIL-STD-1399 and RTCA DO-160.
Required probes:
●
Differential voltage probe
●
Current probe

from other measurements and is used for all power measurements. For a description
of the reference level settings, see Chapter 11.2.3, "Reference level", on page 259.

Channel
Select the channel for the offset compensation.
AutoZero, Use AutoZero
Differences in DUT and oscilloscope ground levels can cause larger zero errors, which
affect the waveform. If the DUT is ground-referenced, the AutoZero function corrects
the zero error of the probe to optimize measurement results at small signal levels. The
validation limit depends on the probe attenuation because probes with high attenuation
often have to compensate high offsets. AutoZero detects offset values even when the
signal is out of the current measurement range.
To correct the zero error of voltage probes, short the signal pin and the ground pin
together and connect them to the ground of the DUT. Then tap "AutoZero". While the
alignment is running, the instrument switches to DC coupling to display the waveform
correctly.
To include the measured offset in measurement results, enable "Use AutoZero".
If a current probe is connected, the function demagnetizes the probe's sensor head
and sets the waveform to zero position.

Values are listed in scientific notation. You can convert the comma-separated text to
columns.
Content of waveform files
The first lines of the file contain header data, for example, time scale, vertical scale,
vertical and horizontal positions. Header data is required to interpret the waveform
data, and to analyze the data values of the data file.
Below the header, the waveform data follows. For each sample, one line is written. The
first value is the X-value (time or frequency), the next is the Y-value in the unit indicated
in the header data. For envelope or peak detect waveforms, two Y-values (minimum
and maximum) are written for each sample.

13.1 Basics of protocol analysis
With the R&S MXO 5 oscilloscope, you can decode selected protocols.
With dual-path protocol analysis, you can set the instrument sample rate for the wave-
form path and the oscilloscope automatically uses another internal decoupled sample
rate for the decoding path. Even with very slow sample rates, the protocol data is cor-
rectly decoded.
With the R&S MXO 5, you can use deep memory to capture more packets. The oscillo-
scope can capture long time periods where the cause and result are distanced in time.
Over the entire capture, signal detail is time-correlated with packet content for fast
debug.

13.2 SPI bus (option R&S MXO5-K510)
The Serial Peripheral Interface SPI is used for communication with slow peripheral
devices, in particular, for transmission of data streams.
Required options and equipment
For performing SPI decode measurements, you need the following equipment:
●
R&S MXO 5 with 4 channels. The channels can be a combination of the following:
– Analog channels (C1-C4)
– Logic channels (D0-D15) (requires option R&S MXO5-B1)
●
Option R&S MXO5-K510
13.2.1 About the SPI protocol
A 4-channel instrument is required for full support of the SPI protocol, or the MSO
option R&S MXO5-B1.
The Serial Peripheral Interface SPI is used for communication with slow peripheral
devices, in particular, for transmission of data streams.
Main characteristics of SPI are:
●
Main-subnode communication
●
No device addressing. The sub is accessed by a chip select, or sub select line.
●
No acknowledgment mechanism to confirm receipt of data
●
Duplex capability
Most SPI buses have four lines, two data and two control lines:
●
Clock line to all subs (SCLK)
●
Sub select or Chip select line (SS or CS)
●
Main data output, sub data input (MOSI or SDI)
●
Main data input, sub data output (MISO or SDO)
When the main generates a clock and selects a sub device, data may be transferred in
either or both directions simultaneously.

Clock polarity
Two settings define the clock mode: the clock polarity and the clock phase. Together,
they determine the edges of the clock signal on which the data are driven and sam-
pled.
A master/slave pair must use the same parameter pair values to communicate. The
clock phase defines the slope. It selects if data is stored with the rising or falling slope
of the clock. The slope marks the begin of a new bit.

13.3 I²C (option R&S MXO5-K510)
The Inter-Integrated Circuit is a simple, low-bandwidth, low-speed protocol used for
communication between on-board devices, for example, in LCD and LED drivers,
RAM, EEPROM, and others.
Required options and equipment
For performing I²C decode measurements, you need the following equipment:
●
R&S MXO 5 with 2 available channels. The channels can be a combination of the
following:
– Analog channels (C1-C4)
– Logic channels (D0-D15) (requires option R&S MXO5-B1)

13.3.1 About the I²C protocol
This chapter provides an overview of protocol characteristics, data format, address
types and trigger possibilities. For detailed information, read the "I2C-bus specification
and user manual" available on the NXP manuals webpage at http://www.nxp.com/.
I²C characteristics
Main characteristics of I²C are:
●
Two-wire design: serial clock (SCL) and serial data (SDA) lines
●
Controller/ target communication: the controller generates the clock and addresses
the targets. Targets receive the address and the clock. Both controller and targets
can transmit and receive data.
●
Addressing scheme: each target device is addressable by a unique address. Multi-
ple target devices can be linked together and can be addressed by the same con-
troller.
●
Read/write bit: specifies if the controller reads (=1) or writes (=0) the data.
●
Acknowledge: takes place after every byte. The receiver of the address or data
sends the acknowledge bit to the transmitter.

The R&S MXO 5 supports all operating speed modes: high-speed, fast mode plus, fast
mode, and standard mode.
Data transfer
The format of a simple I²C message (frame) with 7-bit addressing consists of the fol-
lowing parts:
●
Start condition: a falling slope on SDA while SCL is high
●
7-bit address of the target device that either is written to or read from
●
R/W bit: specifies if the data is written to or read from the target
●
ACKnowledge bits: is issued by the receiver of the previous byte if the transfer was
successful
Exception: At read access, the controller terminates the data transmission with a
NACK bit after the last byte.
●
Data: several data bytes with an ACK bit after every byte
●
Stop condition: a rising slope on SDA while SCL is high
Figure 13-5: I2C writes access with 7-bit address
Address types: 7-bit and 10-bit
Target addresses can be 7 bits or 10 bits long. A 7-bit address requires 1 byte, 7 bits
for the address followed by the R/W bit.
A 10-bit address for write access requires 2 bytes: the first byte starts with the reserved
sequence 11110, followed by the two MSB of the address and the write bit. The second
byte contains the remaining 8 LSB of the address. The target acknowledges each
address byte.
Figure 13-6: 10-bit address, write access
A 10-bit address for read access requires 3 bytes. The first 2 bytes are identical to the
write access address. The third byte repeats the address bits of the first byte and sets
the read bit.

lines must be connected to the input channels, triggering on math and reference wave-
forms is not possible.
You can trigger on:

Start or stop condition
●
Repeated start condition
●
Transfer direction (read or write)

13.5 CAN (option R&S MXO5-K520)
CAN is the Controller Area Network, a bus system designed by Bosch for use within
automotive network architecture, for example, for brake, power train and engine man-
agement. Today, it is also used in many other systems, for example, in industrial
machines, aerospace, subsea, merchant marine.
With the R&S MXO 5 you can decode frames from some of the most common CAN
protocols standards:
●
Classical CAN (CAN 2.0): with the standard frame format (11-bit identifier) and the
extended frame format (29-bit identifier).
●
CAN FD: CAN with flexible data rate. It is an extension of the classical CAN proto-
col and allows for increased data rates and payloads. It is backward compatible
with CAN 2.0.
●
CAN XL: an advanced version of the CAN protocol designed to handle higher data
rates and larger payloads compared to classical CAN and CAN FD.
Required options and equipment
For performing CAN decode measurements, you need the following equipment:
●
R&S MXO 5 with 1 available channel. The channel can be:
– Analog channels (C1-C4)
– Logic channels (D0-D15) (requires option R&S MXO5-B1)
●
One probe

13.5.1.3 CAN symbols
For the CAN protocol, you can upload symbol lists containing IDs and a symbolic name
for each node. You can load a file in one of the supported formats: DBC and CSV.
DBC files for CAN and CAN FD
Industry standard DBC files contain more information than CSV files and translate the
abstract decode results to human language. For each frame, the frame ID and the
symbolic name of the ID are given. The frames are also called messages in CAN. The
data of a CAN message can consist of several "signals". The DBC file provides the
label, unit, start bit, length and other indicators for each signal. For state-encoded sig-
nals, the meaning of the states is given.
In the following demo example, the message "EngineData" has the decimal ID
2,166,573,756 and consists of 8 data bytes. These 8 bytes are defined as 6 signals.
The first one, "PetrolLevel", starts at bit #24, has a length of 8 bit, and the unit is liter.
The signal "IdleRunning" is state-encoded. It has only one bit. The binary value 0
means "Running", and the binary value 1 means "Idle".
Example: CAN DBC file section
BO_ 2166573756 EngineData: 8 Engine
SG_ PetrolLevel : 24|8@1+ (1,0) [0|255] "l" ...
SG_ EngPower : 48|16@1+ (0.01,0) [0|350] "kW" ...
SG_ EngForce : 32|10@1+ (1,0) [0|1000] "N" ...
SG_ IdleRunning : 23|1@1+ (1,0) [0|1] "" ...
SG_ EngTemp : 16|7@1+ (2,-50) [-50|150] "degC" ....
SG_ EngSpeed : 0|13@1+ (1,0) [0|8000] "rpm" ...
....
VAL_ 2166573756 IdleRunning 0 "Running" 1 "Idle" ;
CSV files for CAN / CAN FD
Symbol list files are protocol-specific. A CSV label file for CAN protocols contains three
values for each identifier:
●
Identifier type, 11-bit or 29-bit long
●
Identifier value
●
Symbolic name of the identifier, specifying its function in the bus network.
Example: CAN CSV file

"Form error"
A form error occurs when a fixed-form bit field contains one or more
illegal bits.
"Bit stuffing
error"
The frame segments Start of Frame, Arbitration Field, Control Field,
Data Field and CRC Sequence are coded by the bit stuffing method.
The transmitter automatically inserts a complementary bit into the bit-
stream when it detects five consecutive bits of identical value in the
bitstream to be transmitted. A stuff error occurs when the 6th consec-
utive equal bit level in the mentioned fields is detected.
"Stuff count
error"
A stuff bit error occurs, if more than five consecutive bits of the same
level occur on the bus.
"Ack error"
An acknowledgment error occurs when the transmitter does not
receive an acknowledgment - a dominant bit during the ACK Slot.
"Checksum
error"
CAN uses the Cyclic Redundancy Check, which is a complex check-
sum calculation method. The transmitter calculates the CRC and
sends the result in the CRC sequence. The receiver calculates the
CRC in the same way. A CRC error occurs when the calculated result
differs from the received value in the CRC sequence.

14 Mixed signal option (MSO, R&S MXO5-B1)
The Mixed Signal Option R&S MXO5-B1 adds logic analyzer functions to the classical
oscilloscope functions. Using the MSO option, you can analyze and debug embedded
systems with mixed-signal designs that use analog signals and correlated digital sig-
nals simultaneously.
The Mixed Signal Option provides 16 digital channels grouped in two logic probes
(pods) with 8 channels each. The instrument ensures that analog and digital wave-
forms are time-aligned and synchronized so that critical timing interactions between
analog and digital signals can be displayed and tested. The automatic alignment com-
pensates the skew between the probe connectors of the analog channels and the
probe boxes of the digital channels.
14.1 Logic configuration
Access: "Menu" > "Logic" > "Setup" tab
Digital channels can be displayed individually, and they can be grouped and displayed
as a logic group. You can configure and enable up to 4 logic groups. Each digital chan-
nel can be assigned to one active logic only, the instrument disables conflicting buses
automatically.
For clocked buses, you can display the decoded data in a result box.
If you have configured several logic groups and you want to modify the settings, make
sure that the tab of the correct logic is selected. Disable the logic before you change
the settings.

Technology,Threshold
Sets the logical threshold. For each sample, the instrument compares the input voltage
with the threshold value. If the input voltage is above the threshold, the signal state "1"
is stored. Otherwise, the signal state "0" is stored if the input voltage is below the
threshold.
To avoid the change of signal states due to noise, a hysteresis is considered.
Threshold
Logic 0 Logic 1 Logic 0
Hysteresis
By default, same threshold and hysteresis value are used for all digital channels and all
logic buses: "Couple thresholds" is enabled.
You can also set different thresholds for the individual channel groups. As long as the
buses are disabled, you can set different thresholds for each bus. Active buses use the
same threshold and hysteresis values, the settings of the last activated bus take effect.
The range of threshold levels and the minimum voltage swing is given in the data
sheet.
"Threshold"

15 Waveform generator (option R&S MXO5-
B6)
The R&S MXO 5 includes a two-channel 100 MHz waveform generator which can gen-
erate a wide range of waveform and modulation types.
With each of the waveform generators, one can output simple functions, modulated
sine waveform, arbitrary waveforms and sweep waveforms. It is possible to couple and
synchronize the settings of the waveform generators.
The instrument preset does not affect the generator settings. Each generator has its
own preset ("Default setup"). When the instrument is shut down, the waveform genera-
tor settings are stored. At instrument start, these settings are restored but the genera-
tors are switched off. When a saveset of instrument settings is recalled, generators are
also switched off but the generator settings remain unchanged.

15.1.4 Arbitrary waveforms
The arbitrary waveform generator allows you to output a user-defined waveform for
testing your devices. An arbitrary waveform is copied from an existing waveform on the
instrument, or loaded from file. You can load CSV files that follow a defined structure,
or saved reference waveforms.
See also: Chapter 15.3.4, "Configuring an arbitrary waveform", on page 405.
15.1.4.1 Arbitrary waveform files
You can load CSV files that have a Rohde & Schwarz WaveGen format.
Content and format of the Rohde & Schwarz arbitrary waveform CSV files
The waveform generator format can contain the following values:
●
Rate
●
Time value
●
Voltage value
If all the values are defined, the file format is as follows:
Rate = 5000000 //Sample rate of the arbitrary waveform.
0.000000E+000,-5.995 //Time value 1, Voltage value 1
1.237011E-005,-6.0 //Time value 2, Voltage value 2
.......
In this case, the rate is reflected in the "Sample Rate" field of the user interface. The
total number of Time/Voltage values is reflected in the "Samples" of the user interface.
Anything written after // is ignored as a comment.
You can define only some of the values. According to what you define, the file format
looks different and is handled differently:
●
With specified Rate:

MXO 5 Series
399User Manual 1802.3369.02 ─ 02
Time values are ignored. You can specify just rate and voltage values as below:
Rate = 5000000 //Sample rate of the arbitrary waveform
-5.995 //Voltage value 1
-6.0 //Voltage value 2
.......
●
Without specified Rate and without specified Time values:
The last user-defined sample rate is used to calculate the waveform. You can
change the "Sample rate" in the user interface. The voltage values are then played
with this sample rate.
-5.995 //Voltage value 1
-6.0 //Voltage value 2
.......
●
Without specified Rate and with specified Time:
The timing information of the first 2 time values is used to calculate the sample
rate.
Example:
Consider the following file:
0.000000E+000,-5.995 //Time value 1, Voltage value 1
1.237011E-005,-6.0 //Time value 2, Voltage value 2
The sample rate is:
Sample rate = 1/ Time between first two samples =1 / 1.237011E-005 =
80.840KSampe/sec

16 Network operation and remote control
The operating system is the basis of the instrument's firmware, it provides basic func-
tions such as logon, password protection, virus protection, and connection to a net-
work.
In addition to working with the R&S MXO 5 directly, using the touchscreen and the
keys, you can also operate the instrument from a remote PC. Various methods of
remote operation and control in a LAN network are supported:
●
Using the web interface
●
Using a VNC client
●
Remote control with SCPI commands
The following descriptions provide information required for operating the R&S MXO 5
remotely. Definitions specified in the SCPI standard are not provided.
For basic knowledge on remote control operation and additional information, see the
following documents, available on the Rohde & Schwarz website:

16.1 Connecting the instrument to the network (LAN)
Network environment
Before connecting the product to a LAN, consider the following:
●
Install the latest firmware to reduce security risks.
●
For internet or remote access, use secured connections if applicable.
●
Ensure that the network settings comply with the security policies of your company.
Contact your local system administrator or IT department before connecting your
product to your company LAN.
●
When connected to the LAN, the product may potentially be accessed from the
internet, which may be a security risk. For example, attackers might misuse or
damage the product.

16.1.1 Connecting the instrument to the network
There are two methods to establish a LAN connection to the instrument:
●
A non-dedicated network (Ethernet) connection from the instrument to an existing
network.
●
A dedicated network connection (Point-to-point connection) between the instru-
ment and a single computer.
To connect a LAN cable
► Connect an RJ-45 cable to the LAN connector on the rear panel, and to the LAN.
For supported LAN interfaces, refer to the data sheet.
16.1.2 Assigning the IP address
Depending on the network capacities, the TCP/IP address information for the instru-
ment can be obtained in different ways.
●
If the network supports the Dynamic Host Configuration Protocol (DHCP), the
address is assigned automatically.
●
If the network does not support DHCP, or if the instrument is set to use manual
configuration, the addresses must be set manually.
By default, the instrument is configured to use DHCP and obtains all address informa-
tion automatically. Thus it is safe to establish a physical connection to the LAN without
any previous instrument configuration.
Ensure that you do not use the IP address range 192.168.0.x to avoid internal address
conflict.
Setting up a manual IP address within this range is rejected by the firmware. If the
automatic DHCP server assigns an IP address within this range, the instrument is not
reachable from this network.
An error message is displayed, if the firmware detects an IP address error:
To assign the IP address manually on the instrument
1.
NOTICE! Connection errors can affect the entire network. If your network does not
support DHCP, or if you choose to disable dynamic TCP/IP configuration, you must
assign valid address information before connecting the instrument to the LAN.

Contact your network administrator to obtain a valid IP address.
2. Open "Menu" > "Settings".
3. Select "System" > "Network" > "Advanced".
4. Disable "Automatic IP (DHCP)".
5. Enter the address information as obtained from the network administrator.
16.1.3 Using host names
In a LAN that uses a DNS server (Domain Name System server), each computer and
instrument in the LAN can be accessed via an unambiguous host name (or computer
name) instead of the IP address. The DNS server translates the host name to the IP
address. Host names are useful when a DHCP server is used, as a new IP address
can be assigned each time the instrument is restarted.
Each instrument is delivered with an assigned host name, but you can change this
name.
The default host name is the device name, a non-case-sensitive string with the follow-
ing syntax: <instrument_model>-<serial_number>.
For example, the default host name of an MXO58 with serial number 123456 is
MXO58-123456.
You can find the current host name, the model and the serial number in the "Device
summary", when you tap the Rohde & Schwarz logo in the upper right corner of the
screen. See also: Chapter 4.11, "Information and notifications", on page 65.
The serial number can also be found on the rear panel of the instrument. It is the third
part of the device ID printed on the barcode sticker:
To change the host name
1. Open the "Menu".
2. Select "Settings" > "System" > "Network".
3. In "Device name", enter the new host name.
4. Confirm the entry.

Changing the LAN parameters requires the "Web Ifc Password" password, which is set
on the instrument.
IP configuration
The "LAN Configuration > IP configuration" webpage displays all mandatory LAN
parameters and allows their modification. Changing the LAN parameters requires the
"Web Ifc Password" password, which is set on the instrument.
The "IP address mode" controls how the IP address for the instrument gets assigned.
For the manual configuration mode, at least the static IP address, subnet mask, and
default gateway are used to configure the LAN. The automatic configuration mode
uses DHCP server or Dynamic Link Local Addressing to obtain the instrument IP
address.
The same settings are available on the instrument under "Menu" > "Settings" > "Sys-
tem" > "Network" > "Advanced".
Advanced configuration
The "LAN Configuration > Advanced configuration" parameters are used as follows:
●
mDNS and DNS-SD are two additional protocols: Multicast DNS and DNS Service
Discovery. They are used for device communication in zero configuration networks
working without DNS and DHCP.
●
"ICMP ping" must be enabled to use the ping utility.
●
"VXI-11" is the protocol that is used to detect the instrument in the LAN.

Ping client
Ping is a utility that verifies the connection between the instrument and another device.
The ping command uses the ICMP echo request and echo reply packets to determine
whether the LAN connection is functional. Ping is useful for diagnosing IP network or
router failures. The ping utility is not password-protected.
To initiate a ping between the compliant instrument and a second connected device:
1. Enable "ICMP ping" on the "Advanced configuration" page (enabled by default).
2. On the "Ping client" page, enter the IP address of the second device without the
ping command and without any further parameters into the "Destination
address" field (e.g. 11.113.11.203).
3. Click "Submit".

The LAN connector is located on rear panel of the
instrument.
The interface is based on TCP/IP and supports vari-
ous protocols.
16.4.1.1 LAN interface
To be integrated in a LAN, the instrument is equipped with a LAN interface, consisting
of a connector, a network interface card and protocols. The interface details are given
in the specifications.
For remote control via a network, the PC and the instrument must be connected via the
LAN interface to a common network with TCP/IP network protocol. They are connected
using a commercial RJ-45 cable (shielded or unshielded twisted-pair category 5 or bet-
ter). The TCP/IP network protocol and the associated network services are preconfig-
ured on the instrument. Software for instrument control and the VISA program library
must be installed on the controller.
IP address
Only the IP address or a valid DNS host name is required to set up the connection.
The host address is part of the "VISA resource string" used by programs to identify and
control the instrument. The VISA resource string has the form:
TCPIP::<host address>::hislip0[,<port>][::INSTR] for HiSLIP protocol
TCPIP::<host address>[::inst0][::INSTR] for VXI-11 protocol
Where:
●
host address identifies the instrument in the network, usually the IP address. If
the LAN is supported by a DNS server, the host name can be used instead of the
IP address. The DNS server (Domain Name System server) translates the host
name to the IP address.
●
hislip0 indicates the HiSLIP protocol.
●
inst0 is the default LAN device name. VISA supports several devices running on
the instrument. On R&S MXO 5, only one device is configured, so the LAN device
name can be omitted.
●
INSTR specifies a VISA resource of the type INSTR. By default, the VISA resource
name control is set to the INSTR class.

16.4.2 Starting and stopping remote control
16.4.2.1 Starting a remote control session
When you switch on the instrument, it is always in manual operation state ("local"
state). It can be operated via the front panel, the touchscreen and external keyboard
and/or mouse.
► To start remote control:
● Send a command from the controller.
● VXI-11 protocol (LAN or USB interface): Use >R interface message.
While remote control is active, the instrument settings are optimized for maximum
measurement speed; the display is switched off. Operation via the front panel is dis-
abled.
On the touchscreen, two buttons appear in the upper left corner: "Local" and "View".
16.4.2.2 Using the display during remote control
You can observe the screen while a remote control script is executed. Displaying the
results of script execution is helpful for program test purposes but tends to slow down
the measurement. Therefore it is recommended that you switch off the display in real
measurement applications where a tested program script is to be executed repeatedly.
► To switch on the display, do one of the following:
● Tap the "View" button in the upper left corner of the touchscreen.
● Use the SYSTem:DISPlay:UPDate ON command.
► To switch off the display, do one of the following:
● Tap the "View" button again.

closed. Besides, you can return to manual operation manually or via remote control.
► To return to manual operation:
● Tap the "Local" button in the upper left corner of the touchscreen.
● VXI-11 protocol: Use >L interface message.
16.5 Remote control - status reporting system
The status reporting system stores all information on the current operating state of the
instrument, and on errors which have occurred. This information is stored in the status
registers and in the error queue. Both can be queried via STATus... commands.

The STatus Byte (STB) register and its associated mask register Service Request
Enable (SRE) form the highest level of the status reporting system. The STB pro-
vides a rough overview of the instrument status, collecting the information of the
lower-level registers.
●
ESR and SCPI registers
The STB receives its information from the following registers:
– The Event Status Register (ESR) with the associated mask register standard
Event Status Enable(ESE).
– The STATus:OPERation and STATus:QUEStionable registers which are
defined by SCPI and contain detailed information on the instrument.

The output buffer contains the messages that the instrument returns to the control-
ler. It is not part of the status reporting system but determines the value of the MAV
bit in the STB and thus is represented in the overview.
All status registers have the same internal structure.
16.5.2 Structure of a SCPI status register
The STATus:OPERation and the STATus:QUEStionable SCPI status registers
consists of five parts.
The individual bits are independent of each other, i.e. each hardware status is
assigned a bit number, which is valid for all five parts. Bit 15 (the most significant bit) is
set to zero for all parts. Thus, the contents of the register parts can be processed by
the controller as positive integers.
Description of the five status register parts
The five parts of a SCPI status register have different properties and functions:
●
CONDition
The CONDition part reflects the current instrument status. For summary bits, the
CONDition bit mirrors the sum of the enabled EVENt bits of the next lower regis-
ter.
This register part can only be read, but not written into or cleared. Its contents are

PTRansition / NTRansition
The two transition register parts define which state transition of the CONDition
part (none, 0 to 1, 1 to 0 or both) is stored in the EVENt part.
The Positive-TRansition part acts as a transition filter. When a bit of the
CONDition part is changed from 0 to 1, the associated PTR bit decides whether
the EVENt bit is set to 1.
– PTR bit =1: the EVENt bit is set.
– PTR bit =0: the EVENt bit is not set.
All positive transitions are enabled by default.
This part can be written into and read as required. Its contents are not affected by
reading.

The Negative-TRansition part also acts as a transition filter. When a bit of the
CONDition part is changed from 1 to 0, the associated NTR bit decides whether
the EVENt bit is set to 1.
– NTR bit =1: the EVENt bit is set.
– NTR bit =0: the EVENt bit is not set.
All negative transitions are disabled by default.
This part can be written into and read as required. Its contents are not affected by
reading.
●
EVENt
The EVENt part indicates whether an event has occurred since the last reading. It
is the "memory" of the condition part. It allows you to detect the occurrence of
events reliably, even if they have changed the state of the CONDition bit for a
very brief interval. It only indicates events passed on by the transition filters.
This part can only be read by the user. Reading the register clears it.
●
ENABle
The ENABle part determines whether the associated EVENt bit contributes to the
summary bit (see below). Each bit of the EVENt part is "ANDed" with the associ-
ated ENABle bit (symbol '&'). The results of all logical operations of this part are
passed on to the summary bit via an "OR" function (symbol '+').
ENABle bit = 0: the associated EVENt bit does not contribute to the summary bit
ENABle bit = 1: if the associated EVENt bit is "1", the summary bit is set to "1" as
well.
This part can be written into and read by the user as required. Its contents are not
affected by reading.
16.5.3 Contents of the status registers
16.5.3.1 Status byte (STB) and service request enable register (SRE)
The STatus Byte (STB) is already defined in IEEE 488.2. It provides a rough over-
view of the instrument status by collecting the pieces of information of the lower regis-
ters. A special feature is that bit 6 acts as the sum bit of the remaining bits of the status
byte.
The STB can thus be compared with the CONDition part of an SCPI register and
assumes the highest level within the SCPI hierarchy.
The STB is read using the command *STB? or a serial poll.
The STatus Byte (STB) is linked to the Service Request Enable (SRE) register.
Each bit of the STB is assigned a bit in the SRE. Bit 6 of the SRE is ignored. If a bit is
set in the SRE and the associated bit in the STB changes from 0 to 1, a service
request (SRQ) is generated. The SRE can be set using the command *SRE and read
using the command *SRE?.

2 Error Queue not empty
The bit is set when an entry is made in the error queue. If this bit is enabled by the SRE, each
entry of the error queue generates a service request. Thus an error can be recognized and
specified in greater detail by polling the error queue. The poll provides an informative error mes-
sage. This procedure is to be recommended since it considerably reduces the problems
involved with remote control.
3 QUEStionable status register summary bit
The bit is set if an EVENt bit is set in the QUEStionable status register and the associated
ENABle bit is set to 1. A set bit indicates a questionable instrument status, which can be speci-
fied in greater detail by querying the STATus:QUEStionable status register.
4 MAV bit (message available)
The bit is set if a message is available in the output queue which can be read. This bit can be
used to enable data to be automatically read from the instrument to the controller.
5 ESB bit
Sum bit of the event status register. It is set if one of the bits in the event status register is set
and enabled in the event status enable register. Setting of this bit indicates a serious error which
can be specified in greater detail by polling the event status register.
6 MSS bit (main status summary bit)
The bit is set if the instrument triggers a service request. This is the case if one of the other bits
of this registers is set together with its mask bit in the service request enable register SRE.
7 STATus:OPERation status register summary bit
The bit is set if an EVENt bit is set in the OPERation status register and the associated
ENABle bit is set to 1. A set bit indicates that the instrument is just performing an action. The
type of action can be determined by querying the STATus:OPERation status register.
16.5.3.2 Event status register (ESR) and event status enable register (ESE)
The ESR is defined in IEEE 488.2. It can be compared with the EVENt part of a SCPI
register. The event status register can be read out using command *ESR?.
The ESE corresponds to the ENABle part of a SCPI register. If a bit is set in the ESE
and the associated bit in the ESR changes from 0 to 1, the ESB bit in the STB is set.
The ESE register can be set using the command *ESE and read using the command
*ESE?.

2 Query error
This bit is set if the controller wants to read data from the instrument without having sent a
query. It is also set if the controller does not fetch requested data and sends new instructions to
the instrument instead. The cause is often a query which is faulty and hence cannot be execu-
ted.
3 Device-dependent error
This bit is set if a device-dependent error occurs. An error message with a number between
-300 and -399 or a positive error number, which denotes the error in greater detail, is entered
into the error queue.
4 Execution error
This bit is set if a received command is syntactically correct but cannot be performed for other
reasons. An error message with a number between -200 and -300, which denotes the error in
greater detail, is entered into the error queue.
5 Command error
This bit is set if a command is received, which is undefined or syntactically incorrect. An error
message with a number between -100 and -200, which denotes the error in greater detail, is
entered into the error queue.
6 User request
This bit is set when the instrument is switched over to manual control.
7 Power on (supply voltage on)

16.5.3.3 STATus:OPERation register
In the CONDition part, this register contains information on which actions the instru-
ment is executing. In the EVENt part, it contains information on which actions the
instrument has executed since the last reading.
It can be read using the commands STATus:OPERation:CONDition? or
STATus:OPERation[:EVENt]?, see also Chapter 17.19.2, "STATus:OPERation reg-

16.5.3.5 Application of the status reporting system
The purpose of the status reporting system is to monitor the status of one or several
instruments in a test system. In particular, it monitors continuous measurements to
detect errors in the signal. The controller must receive and evaluate the information of
all devices.
The following standard methods are used:
●
Service request: An SRQ is initiated by the instrument.
●
Query of a specific register by commands
●
Query of the error queue
These methods are described in the following sections.
Service request
The instrument can send a service request (SRQ) to the controller. Usually, this service
request initiates an interrupt at the controller, to which the control program can react
appropriately.
An SRQ is initiated if one or several of bits 2, 3, 4, 5 or 7 of the STB are set and
enabled in the SRE. Each of these bits combines the information of a lower-level regis-
ter, the error queue or the output buffer.
The ENABle parts of the status registers can be set such that arbitrary bits in an arbi-
trary status register initiate an SRQ. To use service requests effectively, set all bits to
"1" in the mask registers SRE and ESE.
The SRQ is the only possibility for the instrument to become active on its own. Config-
ure the instrument so that it initiates a service request if errors occur. And ensure that
your program reacts appropriately to service requests.
Query of a register
The STB and ESR registers contain 8 bits, the SCPI registers 16 bits. The contents of
a status register are specified and transferred as a single decimal number. Therefore,
each bit is assigned a weighted value. The decimal number is calculated as the sum of
the weighted values of all bits in the register that are set to 1.

R&S
®
MXO 5 Series
426User Manual 1802.3369.02 ─ 02
Example:
The decimal value 40 = 32 + 8 indicates that bits no. 3 and 5 in the status register (e.g.
the QUEStionable status summary bit and the ESB bit in the STatus byte) are set.
16.5.4 Error queue
Each error state in the instrument leads to an entry in the error queue.
The error queue should be queried after every SRQ in the controller program as the
entries describe the cause of an error more precisely than the status registers. Espe-
cially in the test phase of a controller program the error queue should be queried regu-
larly since faulty commands from the controller to the instrument are recorded there as
well.
16.5.5 Reset values of the status reporting system
The following table contains the different commands and events causing the status
reporting system to be reset. None of the commands, except *RST and
SYSTem:PRESet, influence the functional instrument settings. In particular, DCL does
not change the instrument settings.

trol.
The description of the remote commands, assume a R&S MXO 5 with the highest
available bandwidth and number of channels. Depending on your model, some of the
available command ranges can differ from the values stated in the following chapters.
17.1 Conventions used in remote command description
The basics of SCPI command structure, syntax and command parameters are
explained in www.rohde-schwarz.com/rc-via-scpi.
The following conventions are used in the remote command descriptions:
●
Command usage
If not specified otherwise, commands can be used both for setting and for querying
parameters.
If a command can be used for setting or querying only, or if it initiates an event, the
usage is stated explicitly.
●
Parameter usage
If not specified otherwise, a parameter can be used to set a value and it is the
result of a query.
Parameters required only for setting are indicated as Setting parameters.
Parameters required only to refine a query are indicated as Query parameters.
Parameters that are only returned as the result of a query are indicated as Return
values.
●
Conformity
Commands that are taken from the SCPI standard are indicated as SCPI con-
firmed. All commands used by the R&S MXO 5 follow the SCPI syntax rules.
●
Asynchronous commands
A command which does not automatically finish executing before the next com-
mand starts executing (overlapping command) is indicated as an Asynchronous
command.
●
Reset values (*RST)
Default parameter values that are used directly after resetting the instrument (*RST
command) are indicated as *RST values, if available.

FORMat[:DATA] [<Format>],[<Length>]
FORMat[:DATA]? [<Format>]
Selects the data type that is used for transmission of data from analog channels, math
and reference waveforms, and some measurement results from the instrument to the
controlling computer.
Setting parameters:
<Length> *RST: ASCii
Parameters for setting and query:
<Format> ASCii | REAL | INT
ASCii
Data values are returned in ASCII format as a list of comma-
separated values in floating point format. The length can be
omitted. It is 0 which means that the instrument selects the num-
ber of digits to be returned. The query returns both values (ASC,
0).
REAL,32
The data is stored as binary data (Definite Length Block Data
according to IEEE 488.2). Each waveform value is formatted in
32-Bit IEEE 754 Floating Point Format.
The schema of the result string is as follows:
#41024<value1><value2>…<value n> with:
#4 = number of digits (= 4 in the example) of the following num-
ber
1024 = number of following data bytes (= 1024 in the example)
<value> = 4-byte floating point values
For large data (≥ 1 GB), the result string starts with "#(data
length)". The number inside the parentheses indicates the real
data length in bytes.
INT,8 | INT,16 | INT,32
Signed integer data with length 8 bit, 16 bit, or 32 bit.
The result string has the same schema as the REAL format.
Fot INT,16 you can set the byte order using the command.
For digital channel data, math and histogram data, INT formats
are not available.

Term Definition
Layout A layout is a SmartGrid configuration. Several configurations can exist but only one
configuration is active.
By default, SmartGrid configurations named "Diagram Set" on the display.
Children A child is an area where data (data table, result table) or waveforms (diagram) are dis-
played. Also a node can be a child (nested node).
Node A node consists of one or two children. A node is created with one child that has con-
tent.
Diagram A diagram displays waveforms, the graphical visualization of data.

17.9 Trigger
Trigger commands use several suffixes.
LEVel<n>, Noise<m>
The suffix indicates the analog channel, for which the command takes effect. C1 has
suffix 1, C2 has suffix 2, and so on.
Event<ev>
The event suffix is always 1 and can be omitted.
Asynchronous commands
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.

TRIGger:MODE <TriggerMode>
Sets the trigger mode which determines the behavior of the instrument with and with-
out a trigger event.
Parameters:
<TriggerMode> AUTO | NORMal | FREerun
AUTO
The instrument triggers repeatedly after a time interval if the trig-
ger conditions are not fulfilled. If a real trigger occurs, it takes
precedence. The time interval depends on the time base.
NORMal
The instrument acquires a waveform only if a trigger occurs.
FREerun
The instrument triggers after a very short time interval - faster
than in AUTO mode. Real triggers are ignored.
*RST: AUTO
Usage: Asynchronous command
Manual operation: See "Trigger mode" on page 153
TRIGger:FORCe
Provokes an immediate single acquisition. Force the trigger if the acquisition is running
in normal mode and no valid trigger occurs. Thus, you can confirm that a signal is
available and use the waveform display to determine how to trigger on it.

TRIGger:HOLDoff:MODE <Mode>
Selects the method to define the holdoff condition.
The trigger holdoff defines when the next trigger after the current will be recognized.
Thus, it affects the next trigger to occur after the current one. Holdoff helps to obtain
stable triggering when the oscilloscope is triggering on undesired events.
Holdoff settings are not available if the trigger source is an external trigger input or
serial bus, and if you trigger on a sequence of events.
Parameters:
<Mode> TIME | EVENts | RANDom | AUTO | OFF
TIME
Defines the holdoff directly as a time period. The next trigger
occurs only after the holdoff time has passed, which is defined
using TRIGger:HOLDoff:TIME).
EVENts
Defines the holdoff as a number of trigger events. The next trig-
ger occurs only when this number of events is reached. The
number of triggers to be skipped is defined with TRIGger:
HOLDoff:EVENts.
RANDom
Defines the holdoff as a random time limited by TRIGger:
HOLDoff:MIN and TRIGger:HOLDoff:MAX. For each acquisi-
tion cycle, the instrument selects a new random holdoff time
from the specified range.
AUTO
The holdoff time is calculated automatically based on the current
horizontal scale.
OFF
No holdoff
*RST:
OFF
Usage: Asynchronous command
Manual operation: See "Holdoff mode" on page 154
TRIGger:HOLDoff:AUTotime?
Returns the resulting holdoff time, if TRIGger:HOLDoff:MODE is set to AUTO: Auto
time = Auto time scaling * Horizontal scale. The auto time scaling factor is defined with

17.10 Waveform analysis
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.

17.11 Data management
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.

zation"
17.11.1 Instrument settings
The Mass MEMory subsystem provides commands to access the storage media and to
save and reload instrument settings.
File and directory names
The <file_name> and <directory_name> parameters are strings. Some commands use
a fixed directory; for others the <file_name> can contain the complete path including
the drive name and all subdirectories. If no complete path is specified, the file location
is relative to the current directory, queried with MMEMory:CDIRectory?. The filename
itself may contain the period as a separator for extensions.
File and directory names can be chosen according to Windows™ conventions; the
restrictions placed on filenames known from DOS systems do not apply. All letters and
numbers are allowed, as well as the special characters "_", "^", "$", "~", "!", "#", "%",
"&", "-", "{", "}", "(", ")", "@" and "`". Reserved filenames are CON, AUX, COM1, ...,
COM4, LPT1, ..., LPT3, NUL and PRN.
The use of wildcards ? and * is not allowed.

17.11.6 Screenshots
The HCOPy subsystem and some other commands control the output of display infor-
mation for documentation purposes. The instrument allows two independent output
configurations which can be set separately with the suffix.
Note that the remote mode is intended for maximum performance. Therefore, the dis-
play does not follow the remote commands constantly. To get a correct screenshot,
turn the display on using SYSTem:DISPlay:UPDate.

Without parameters, the complete waveform is retrieved. Using the offset and length
parameters, data can be retrieved in smaller portions, which makes the command
faster. If you send only one parameter, it is interpreted as offset, and the data is
retrieved from offset to the end of the waveform.

17.13 Cursor measurements
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.

CALCulate:SPECtrum<sp>:FREQuency:WINDow:TYPE <WindowFunction>
Selects the window type. Windowing helps minimize the discontinuities at the end of
the measured signal interval and thus reduces the effect of spectral leakage, increas-
ing the frequency resolution.
Various different window functions are provided in the R&S MXO 5 to suit different
input signals. Each of the window functions has specific characteristics, including some
advantages and some trade-offs. Consider these characteristics carefully to find the
optimum solution for the measurement task.

poor amplitude accuracy and is recommended for separating
two tones with almost equal amplitudes and a small frequency
distance.

HAMMing
The Hamming window is bell shaped and has a good frequency
resolution and fair amplitude accuracy. It is recommended for
frequency response measurements and sine waves, periodic
signals and narrowband noise.
HANN
The Hann window is bell shaped and has a slightly worse fre-
quency resolution but smaller sidelobe level than the Hamming
window. The applications are the same.
BLACkharris
The Blackman window is bell shaped and has a poor frequency
resolution, but very good amplitude accuracy. It is recommended
mainly for signals with single frequencies to detect harmonics.
GAUSsian
Good frequency resolution and best magnitude resolution, rec-
ommended for weak signals and short duration
FLATTOP2 = FLATtop2
The flat top window has a poor frequency resolution, but the
best amplitude accuracy and the sharpest sidelobe. It is recom-
mended for accurate single tone amplitude measurements.
KAISerbessel
The kaiser-bessel window has a fair frequency resolution and
good amplitude accuracy, and a very high sidelobe level. It is
recommended for separating two tones with differing amplitudes
and a small frequency distance.

Returns the data of the spectrum points for transmission from the instrument to the
controlling computer. The data can be used in MATLAB, for example.
Without parameters, the complete waveform is retrieved. Using the offset and length
parameters, data can be retrieved in smaller portions, which makes the command
faster. If you send only one parameter, it is interpreted as offset, and the data is
retrieved from offset to the end of the waveform.
To set the export format, use FORMat[:DATA] on page 439.

17.15.2 Power analysis (option R&S MXO5-K31)
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.

17.17 Mixed signal option (option R&S MXO5-B1)
This chapter describes the remote commands of MSO option R&S MXO5-B1.
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.

zation"

17.18 Waveform generator (option R&S MXO5-B6)
This chapter describes the remote commands of the waveform generator.
The instrument preset does not affect the generator settings. Each generator has its
own preset: WGENerator<wg>:PRESet.
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.

17.19.1 General commands
STATus:PRESet
Resets the status registers.
All PTRansition bits are set to 1, i.e. all transitions from 0 to 1 are detected.
All NTRansition bits are set to 0, i.e. a transition from 1 to 0 in a CONDition bit is
not detected.
All EVENt bits are set to 0.
The ENABle bits of STATus:OPERation and STATus:QUEStionable are set to 0,
i.e. all events in these registers are not passed on.
Usage:
Setting only
SCPI confirmed
17.19.2 STATus:OPERation register

Query OPC status in the event status register
If you activate a time-consuming operation and wait for completion with *OPC?, a time-
out could occur before the operation is finished and you do not receive the returned

“1”. In addition, the test program is blocked while waiting with *OPC?. It is not possible
to process other (not interdependent) commands in the meantime or to communicate
with other instruments.
Thus, for time-consuming operations, you can avoid blocking the communication by
sending the operation complete command *OPC:
*CLS
*OPC
Afterwards you can poll the operation complete status in the event status register with
*ESR?.
This query returns the content of the event status register and afterwards clears the
content. See also Chapter 16.5.3.2, "Event status register (ESR) and event status
enable register (ESE)", on page 422.
