connector, this signal is used as the external reference source and "Ext
Ref" is displayed in the status bar of the user interface. When the
external reference is lost, transfinite or not connected, the instrument
swithes to its internal reference source automatically and "Ext Ref" on the
screen disappears.
The [10MHz IN] and [10MHz OUT] connectors are usually used to
build synchronization among multiple instruments.
6. 10MHz OUT
DSA700 can use internal or external reference source.
When internal reference source is used, the [10MHz OUT] connector
can output a 10 MHz clock signal generated by the analyzer. This signal
can be used to synchronize other instruments.
The [10MHz OUT] and [10MHz IN] connectors are usually used to
build synchronization among multiple instruments.
7. TRIGGER IN
In external trigger mode, the connector receives an external trigger signal
through a BNC cable.
8. LAN Interface
Through this interface, the analyzer can be connected to your local network
for remote control. An integrated testing system can be built quickly, as the
analyzer conforms to LXI Core 2011 Device instrument standards.
9. USB Device Interface
The analyzer can serve as a "slave" device to connect external USB devices.
Through this interface, a PictBridge printer can be connected to print screen
image or a PC can be connected to control DSA700 remotely through
programming or PC software.

"Span".
In Zero Span mode, the start frequency, stop frequency and center frequency
are always the same. If one is changed, the others are updated to match.
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
Freq Offset
You can set a frequency offset value to account for frequency conversions between
the device under test and the input terminal of the spectrum analyzer.
Key Points:
The change of this parameter only changes the display values of the center
frequency, start frequency and stop frequency; but does not impact any
hardware settings of the spectrum analyzer.
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
To eliminate an offset, you can perform Preset operation or set the frequency
offset to 0Hz.
Chapter 2 Front Panel Operation RIGOL

2-5
CF Step
Set the step of center frequency. Changing the center frequency in a fixed step
continuously switches the channel to be measured.
Key Points:
The CF step can be set in "Manual" or "Auto" mode. In Auto mode, the CF step
is 1/10 of the span in Non-zero span mode or equals the RBW while in Zero
span mode; in Manual mode, you can set the step using the numeric keys.
After you set an appropriate CF step and select Center Freq, use the up and
down direction keys to switch between measurement channels in a specified
step in order to sweep the adjacent channel manually.
You can modify this parameter using the numeric keys, knob or direction keys.

Key Points:
When Signal Track is turned on, the ST (Signal Track) icon
is highlighted
in the status bar at the left of the screen.
If an active marker currently exists, when Signal Track is enabled, the
instrument will search for and mark the point (with no more than 3 dB
variation in amplitude) near the marker as well as set the frequency of this
point as the center frequency to hold the signal at the center of the screen.
If no marker is currently active, when Signal Track is enabled, the instrument
will activate Marker 1, execute a peak search automatically and set the
frequency of the current peak as the center frequency to hold the signal at the
center of the screen.
In continuous sweep, the system tracks the signal continuously; in single
sweep, the instrument only performs a single signal track; in Zero Span,
Signal Track is invalid.

CF -> Step
Set the current center frequency as the CF step. At this point,
the CF step will switch to "Manual" mode automatically. This function is usually
used with channel switching. Take harmonic waveform measurement for example:
locate a signal at the center frequency of a channel, execute CF-> Step and then
press the down direction key continuously to measure each order of harmonic in
sequence.
SPAN
Set the span of the analyzer. The change of this parameter will affect the frequency
parameters and restart the sweep.
Span
Set the frequency range of the current channel. Press this key to switch to center
frequency/span input mode. The center frequency and span are displayed at the
lower left and right sides of the grid respectively.
Key Points:
The start and stop frequencies vary with the span when the center frequency
is constant.
In manual span mode, the span can be set down to 100 Hz (the only way into
the zero-span mode is pressing the Zero Span menu option) and up to the
full span described in "
Specifications". When the span is set to the
maximum, the analyzer enters full span mode.
Modifying the span in non-zero span mode may cause an automatic change in
both CF step and RBW if they are in Auto mode. Besides, the change of RBW
may influence VBW (in Auto VBW mode).
Variation in the span, RBW or VBW would cause a change in the sweep time.
In non-zero span mode, neither "Video" trigger nor "1/Δtime" readout
function is valid.
You can modify this parameter using the numeric keys, knob or direction keys.
Chapter 2 Front Panel Operation RIGOL
User’s Guide for DSA700 Series
2-9
For more details, please refer to "Parameter Setting".
Full Span
Set the span of the analyzer to the maximum.
Zero Span
Set the span of the analyzer to 0 Hz. Both the start and stop frequencies will equal
the center frequency and the horizontal axis will denote time. The analyzer
measures the time domain characteristics of the amplitude of the corresponding
frequency point on the input signal.
Key Points:
As opposed to Non-zero span, the screen shows the time domain characteristics of
the fixed frequency component of the signal in zero span mode.
The following functions are invalid in Zero span mode:
FREQ: Peak->CF and Signal Track;
SPAN: Zoom In, Zoom Out and X Scale;
Marker->: Mkr->CF, Mkr->Step, Mkr->Start, Mkr->Stop, MkrΔ->CF and
MkrΔ->Span;
Marker Readout: Frequency, Period and 1/ΔTime (valid in Delta marker
type).
Zoom In
Set the span to half of its current value. At this point, the signal on the screen is
zoomed in to observe signal details.
RIGOL Chapter 2 Front Panel Operation
User’s Guide for DSA700 Series
2-10
Zoom Out
Set the span to twice the current value. At this point, the signal on the screen is
zoomed out to gain more information about the signal.
Last Span
Set the span to the previous span setting.
X Scale
Select the scale type of X-axis to Lin or Log. The default is Lin.
Key Points:
In Log scale type, the frequency scale of X-axis is displayed in the logarithmic
form.
When the scale type of X-axis is set to Log and any advanced measurement
function (including T-Power, ACP (Adjacent Channel Power), Chan Pwr
(Channel Power), OBW (Occupied Bandwidth), EBW (Emission Bandwidth),
C/N Ratio, Harmo Dist (Harmonic Distortion) and TOI (Third Order
Intermodulation)) is selected, the instrument switches the scale type of X-axis
to Lin automatically.

between the device under measurement and the analyzer.
Key Points:
The change of this value changes both the reference level readout and the
amplitude readout of the marker; but does not impact the position of the
curve on the screen.
You can modify this parameter using the numeric keys. For more details,
please refer to "Parameter Setting".
Auto Range
Adjust the amplitude parameters within the current span range automatically in
order to display the whole signal optimally on the screen.

Key Points:
Unlike Auto Scale, this function can solve the problem of signal overrange due
to parameter settings and adjust the maximum mixing level according to the
signal under measurement.
Unlike Auto, this function adjusts the signal within the current channel and
does not modify the channel frequency setting. While, Auto will search for
signal within the full frequency range and locate the signal at the center
frequency.

MaxMixL
Set the max input level of the mixer according to the magnitude of the signal.
Key Points:
For a larger input signal, select a smaller maximum mixing level to increase
the input attenuation and reduce the distortion of the signal; for a smaller
input signal, select a larger maximum mixing level to reduce the input
attenuation and noise.
Parameters in inequality (2-3) are always modified on the basis of the
maximum mixing level.
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
Input Impedance
Set the input impedance for voltage-to-power conversions (refer to equation (2-4)).
The default is 50 Ω. To measure a 75 Ω device, you should use a 75 Ω to 50 Ω
adapter (option) supplied by RIGOL to connect the analyzer with the system
under test and then set the input impedance to 75 Ω.
Note: "75 Ω" will be shown in the status bar on the screen in this situation.

Sweep and Function Settings
BW/Det
Set the RBW (Resolution Bandwidth), VBW (Video Bandwidth) and detector type
parameters of the analyzer.
RBW
Set the desired resolution bandwidth in order to distinguish between signals which
are close in frequency.
Key Points:
Reducing RBW will increase the frequency resolution, but will increase the
sweep time (Sweep Time is affected by a combination of RBW and VBW when
it is in Auto mode).
RBW varies with the span (non-zero span) in Auto RBW mode.
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
Note: If the detector type is "Quasi-Peak" or the filter type is "EMI", RBW can be
200 Hz, 9 kHz or 120 kHz only.
VBW
Set the desired video bandwidth in order to filter out the noise outside the video
band.
Key Points:
Reducing the VBW will smooth the spectrum line to differentiate small signals
from noise, but will increase the sweep time (Sweep Time is affected by a
combination of RBW and VBW when it is in Auto mode).
RIGOL Chapter 2 Front Panel Operation
User’s Guide for DSA700 Series
2-22
VBW varies with RBW when it is set to Auto. While in Manual mode, VBW is
not affected by RBW.
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
V/R Ratio
Set the ratio of VBW to RBW.
Key Points:
This value is different while measuring different kinds of signals:
Sine signal: use 1 to 3 (for faster sweeps)
Pulse signal: use 10 (to reduce the influence on the amplitude of transient
signals)
Noise signal: generally use 0.1 (to obtain the average of noises)
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
Detector Type
The analyzer displays the sweeped signal on the screen in the form of trace.
For each trace point, the analyzer always captures all the data within a specific
time interval and processes (Peak, Average,etc.) the captuered data using the
detector currently selected, then display the processed data (one point) on the
screen .
Key Points:
Select an appropriate detector type according to the actual application in
order to ensure the accuracy of the measurement.
The available types are Pos Peak, Neg Peak, Sample, Normal, RMS Avg,
Voltage Avg and Quasi-Peak. The default is Pos Peak.
The corresponding icon (as shown in the figure below) of the detector type
selected is displayed in the status bar at the left side of the screen.
Chapter 2 Front Panel Operation RIGOL
User’s Guide for DSA700 Series
2-23
Pos Peak
For each trace point, Positive Peak detector displays the maximum value of
data sampled within the corresponding time interval.
Neg Peak
For each trace point, Negative Peak detector displays the minimum value of
data sampled within the corresponding time interval.
Sample
For each trace point, Sample detector displays the transient level
corresponding to the central time point of the corresponding time interval.
This detector type is applicable to noise or noise-like signal.
Normal
Normal detector (also called rosenfell detector) displays the maximum value and
the minimum value of the sample data segment in turn; namely for an
odd-numbered data point, the maximum value is displayed; for an
even-numbered data point, the minimum value is displayed. In this way, the
amplitude variation range of the signal is clearly shown.
RMS Avg
For each data point, perform mean square root operation (see equation (2-8))
of the sampled data within the corresponding time interval and display the
result. In this type, noise can be rejected and weak signals can be clearly
observed.

Quasi-Peak (an option for DSA700)
It is a weighted form of peak detector. For each data point, the detector detects
the peaks within the corresponding time interval. The peaks detected are
weighted using circuit with specified charge and discharge structures as well as
the display time constant specified in the CISPR Publication 16 standards and
the result is displayed. Quasi-Peak detector is applicable to EMI testing.
Note: Compared to the discharge time, the charge time of Quasi-Peak
detector is much shorter and can reflect the amplitude as well as time
distribution of the signal.
Filter Type
Set the RBW filter type.
Key Points:
DSA700 supports two kinds of RBW filters: "Gause" (-3 dB bandwidth) and
"EMI" (-6 dB bandwidth).
When "EMI" is selected, resolution bandwidth can be 200 Hz, 9 kHz or 120
kHz only.
The default is "Gause"; the instrument will switch to "EMI" filter automatically
when "Quasi-Peak" detector is selected.

Sweep/Trig
Set parameters about the Sweep and Trigger functions, including sweep time, auto
sweep time, sweep mode, number of sweep, trigger type, etc.
Sweep Time
Set the time needed for the spectrum analyzer to finish a sweep within the span
range. The sweep time can be set in "Auto" or "Manual" mode and the default is
"Auto".
Key Points:
In non-zero span, the analyzer selects the shortest sweep time on the basis of
the current RBW and VBW settings if Auto is selected.
Decreasing the sweep time would speed the measurement. However, an error
may be caused if the specified sweep time is less than the minimum sweep
time in Auto coupling; at this point, "UNCAL" is shown in the status bar on the
screen.
You can modify this parameter using the numeric keys, knob or direction keys.
For more details, please refer to "Parameter Setting".
Auto SWT
Set the auto setting method of the sweep time to "Normal" or "Accy". The sweep
will be faster if "Normal" is selected; while in "Accy" type, higher measurement
precision can be obtained.
Mode
Set the sweep mode to "Single" or "Cont". The default is "Cont". The
corresponding icon of the sweep mode will be displayed in the status bar at the left

Trace/P/F
The sweep signal is displayed as a trace on the screen. In addition, DSA700
provides the Pass/Fail (P/F) test function. Trace/P/F is used to set parameters
related to the trace and P/F test.
Select Trace
DSA700 allows for up to four traces to be displayed at the same time. Each trace
has its own color (Trace 1 - yellow, Trace 2 - purple, Trace 3 - light blue and Trace
4 - green). All traces can be set freely except Trace 4 (a math operation trace that
can only be obtained using the other three traces).
Select Trace 1, Trace 2 or Trace 3 to set the corresponding parameters. By default,
Trace 1 is selected and turned on. The default trace type is Clear Write.
Note: The trace currently displayed on the screen can be stored in the internal or
external memory of the analyzer and can be recalled when needed. Press
Storage to save the trace according to the method introduced in "Storage
".
Trace Type
Set the type of the current trace or disable it. The system calculates the sampled
data using a specific operation method according to the trace type selected and
displays the result. Trace types include Clear Write, Max Hold, Min Hold, Video Avg,
Power Avg and Freeze. The corresponding icon of the trace type will be displayed
in the status bar at the left of the screen. Take Trace 1 (yellow) as an example and
the icons are as shown in the figure below.
1. Clear Write

Delta
One of the marker types. It is used to measure the delta values of X (Frequency or
Time) and Y (Amplitude) between the reference point and a certain point on the
trace. When selected, a pair of markers appears on the trace: Reference Marker
(marked by a combination of the marker number and letter "R", such as "1R") and
the Delta Marker (marked by the marker number, such as "1").
Key Points:
A reference marker will be activated at the position of the current marker if an
active marker currently exists; or else both the reference marker and delta
marker will be simultaneously activated at the center frequency.
The location of the reference marker is always fixed (both on the X-axis and
the Y-axis); while the Delta Marker is active. You can use the numeric keys,
knob or direction keys to change the location of the Delta Marker.
The frequency (or time) delta and amplitude delta between the two markers
are displayed at the upper right corner of the screen.
There are two methods for defining a point as the reference point:
a) Open a "Normal" marker and locate it onto a point. Then, switch the
marker type to "Delta"; at this time, this point is the reference point. You
can modify the location of the delta point to achieve delta measurement.
b) Open a "Delta" marker and locate it onto a point. Then, reselect the
Delta menu to locate the reference marker onto this point. You can
modify the location of the delta point to achieve delta measurement.
When the Noise Mkr function under the Marker Fctn menu is activated, the
result of the noise measurement will be corrected automatically and be
normalized to 1 Hz.

Delta Pair
One of the marker types. When selected, a pair of markers will appear on the trace:
Reference Marker (marked by a combination of the marker number and letter "R",
such as "1R") and the Delta Marker (marked by the marker number, such as "1").
Key Points:
You can use the numeric keys, knob or direction keys to set the locations of
the reference marker (selecting "Ref") and the delta marker (selecting "Delta")
respectively.
This is different from the Delta type marker in that you can modify both the
reference (selecting "Ref") and delta (selecting "Delta") points. Additionally,
both the X and Y values of the reference marker are stable for "Delta" marker
during the sweep; but the Y value of the reference marker updates along with
the sweep for "Delta Pair" marker.
Span Pair
One of the marker types. When selected, a pair of markers will appear on the trace:
Reference Marker (marked by a combination of the marker number and letter "R",
such as "1R") and the Delta Marker (marked by the marker number, such as "1").
Key Points:
You can use the numeric keys, knob or direction keys to set the locations of
both the reference marker and delta marker at the same time.
If "Span" is selected, setting the "Span Pair" will keep the center position of
the two markers unchanged and move them towards the two sides (value
increases) or the middle (value decreases).
If "Center" is selected, setting the "Span Pair" will keep the relative distance
between the two markers unchanged and move their center position left
(value decreases) or right (value increases).
This is different from the "Delta" type marker in that you can modify both the
reference marker and delta marker at the same time.

first set it to Normal type automatically; then measure the average noise level
at the marked point and normalize this value to 1 Hz bandwidth. During this
process, certain compensation is always made on the basis of the detection
and trace types. The measurement will be more precise if RMS Avg or Sample
detection type is used.
This function can be used for measuring the C/N ratio.
N dB BW
Enable the N dB BW measurement or set the value of N dB.
The N dB BW denotes the frequency difference between two points that are
located on both sides of the current marker and with N dB fall (N<0) or rise (N>0)
in amplitude as shown in the figure on the next page.

Message Description
-100
Command error.
A generic syntax error indicates that the device cannot detect more
specific errors. This code indicates that only Command Error defined in
IEEE 488.2,11.5.1.1.4 has been found.
-101 Invalid character.
The syntactic element contains an invalid character; for example, the
command header contains an ampersand (SETUP&). This error might
be used in place of errors -114, -121, -141 and perhaps some others.
-102 Syntax error.
An unrecognizable command or data type was encountered; for
example, a string not supported by the device was received.
-103 Invalid separator.
The parser was expecting a separator but recieved an illegal character;
for example, the semicolon following a program message was omitted:
*EMC 1:CH1:VOLTS 5.
-104
Data type error.
The parser recognized a data element other than the one allowed; for
example, numeric or string data was expected but block data was
encountered.
-105 GET not allowed.
A Group Execute Trigger was contained in a program message (see
IEEE 488.2, 7.7).
-108 Parameter not allowed.
More parameters were received than expected for the command
header; for example, the *EMC common command only accepts one
parameter, so *EMC 0, 1 is not allowed.
-109 Missing parameter.
Fewer parameters were contained than required in the command
header; for example, the *EMC common command requires one
parameter, so *EMC is not allowed.
-110
Command header error.
RIGOL Chapter 4 Troubleshooting&Message
User’s Guide for DSA700 Series
4-10
An error was detected in the command header. This error message is
always used when the device cannot detect more specific errors
described in errors -111 to -119.
-111
Header separator error.
An illegal command header separator was encountered while parsing
the command header; for example, no space is allowed following the
command header, thus *GMC"MACRO" is wrong.
-112 Program mnemonic too long.
The command header contains more that twelve characters (see IEEE
