Figure 6 To Connect to Power Supply
Power-on Inspection
When the oscilloscope is energized, press the power key at the lower-left corner of
the front panel to start the oscilloscope. During the start-up process, the
oscilloscope performs a series of self-tests and you can hear the sound of relay
switching. After the self-test is finished, the welcome screen is displayed.
Connect the Probe
Connect the Probe:
1. Connect the BNC terminal of the probe to a channel BNC connector of the
oscilloscope at the front panel.
2. Connect the probe tip to the circuit point to be tested and connect the ground
alligator clip of the probe to the circuit ground terminal.
Function Inspection
1. Press the Default button on the front panel to restore the instrument to its
default configuration.
2. Connect the ground alligator clip of the probe to the “Ground Terminal”
under the probe compensation signal output terminal.

3. Use the probe to connect the input terminal of CH1 of the oscilloscope and the
“Compensation Signal Output Terminal” of the probe.
4. Press the
Auto Setup.
5. Observe the waveform on the display. In normal condition, the display should
be a square waveform as shown in the figure below:
Figure 7 Function Inspection
6. Use the same method to test the other channels. If the square waveforms
actually shown do not match that in the figure above, please perform “Probe
Compensation”
in the next section.
WARNING
To avoid electric shock during the use of probe, please make sure that
the insulated wire of the probe is in good condition and do not touch the
metallic part of the probe when the probe is connected to high voltage
source
Probe Compensation
When the probes are used for the first time, you should compensate the probes to
match the input channels of the oscilloscope. Non-compensated or poorly

compensated probes may cause measurement inaccuracy or error. The probe
compensation procedures are as follows.
1. Set the switch to 10X on the probe.
2. Perform steps 1, 2, 3 and 4 of “Function Inspection” in the previous section.
3. Check the waveforms displayed and compare them with the following:

Enable the Channel
The oscilloscope provides 2/4 analog input channels and provides independent
vertical control system for each channel. As the vertical system setting methods of
every channel is the same, this chapter takes CH1 as an example to introduce the
setting method of the vertical system.
Connect a signal to the CH1 channel connector; and then press the
CH1 button in
the vertical control area (VERTICAL) at the front panel to enable CH1.
The channel setting menu is displayed at the bottom of the screen and the channel
label at the right side of the screen. The information displayed in the channel label
is related to the current channel setting.
After the channel is turned on, modify the parameters such as the vertical scale, the
horizontal time base and the trigger mode according to the input signal to make
the waveform display easy to observe and measure.
Note: to turn off the channel, press the channel button twice.
SDS1000X-E&SDS1000X-U User Manual

WWW.SIGLENT.COM
Note: push the VERTICAL Variable Knob to quickly switch between Coarse and
Fine adjustments.
Adjust Scale
The vertical scale can be adjusted in
Coarse or Fine mode.
Coarse adjustment (take counterclockwise as an example): set the vertical
scale in 1-2-5 step namely 500uV/div, 1 mV/div, 2 mV/div, 5 mV/div, 10
mV/div …10 V/div.
Fine adjustment: further adjust the vertical scale within a relatively smaller
range to improve vertical resolution. For example: 2 V/div, 1.98V/div,
1.96V/div, 1.94 V/div …1 V/div.
If the amplitude of the input waveform is a little bit greater than the full scale
under the current scale and the amplitude would be a little bit lower if the next
scale is used, fine adjustment can be used to improve the amplitude of
waveform display to view signal details.
Press the
CH1 button on the front panel; then press the Adjust soft key to select the
desired mode. Turn the VERTICAL Variable Knob to adjust the vertical scale
(clockwise to reduce the scale and counterclockwise to increase).
The scale information in the channel label at the right side of the screen will
change accordingly during the adjustment. The adjustable range of the vertical
scale is related to the probe ratio currently set. By default, the probe attenuation
factor is 1X and the adjustable range of the vertical scale is from 500uV/div to 10
V/div.

Overview
To understand the oscilloscope's sampling and acquisition modes, it is helpful to
understand sampling theory, sample rate and oscilloscope bandwidth and sample
rate.
Sampling Theory
The Nyquist sampling theorem states that for a limited bandwidth (band- limited)
signal with maximum frequency f
MAX
, the equally spaced sampling frequency f
S
must be greater than twice the maximum frequency f
MAX
, in order to have the signal
be uniquely reconstructed without aliasing.
f
MAX
= f
S/2
= Nyquist frequency (f
N
) = folding frequency
Sample Rate
The maximum sample rate of the oscilloscope is 2GSa/s. The actual sample rate of
the oscilloscope is determined by the horizontal scale. Turn the
Horizontal Scale
Knob to adjust the sample rate.
The actual sample rate is displayed in the information area at the upper- right
corner of the screen.
The influence on the waveform when the sample rate is too low:
1. Waveform Distortion: when the sample rate is too low, some waveform details
are lost and the waveform displayed is rather different from the actual signal.
SDS1000X-E&SDS1000X-U User Manual
44
WWW.SIGLENT.COM
2. Waveform Confusion: when the sample rate is lower than twice the actual
signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt
from the sample data is lower than the actual signal frequency. The most
common aliasing is the jitter on fast edge.
3.
Waveform Leakage: when the sample rate is too low, the waveform rebuilt
from the sample data does not reflect all the actual signal information.
Bandwidth and Sample Rate
An oscilloscope's bandwidth is typically described as the lowest frequency at which
input signal sine waves are attenuated by 3 dB (- 30% amplitude error).
At the oscilloscope bandwidth, sampling theory says the required sample rate is f
S
= 2f
BW
. However, the theory assumes there are no frequency components above f
MAX
(f
BW
in this case) and it requires a system with an ideal brick- wall frequency
response.

However, digital signals have frequency components above the fundamental
frequency (square waves are made up of sine waves at the fundamental frequency
and an infinite number of odd harmonics), and typically, for 500 MHz bandwidths
and below, oscilloscopes have a Gaussian frequency response.
So, in practice, an oscilloscope's sample rate should be four or more times its
bandwidth: f
S
= 4fBW. This way, there is less aliasing, and aliased frequency
components have a greater amount of attenuation.

Memory Depth
Memory depth refers to the number of waveform points that the oscilloscope can
store in a single trigger sample and it reflects the storage ability of the sample
memory.
Press the Acquire button on the front panel; press the Mem Depth softkey and then
turn the Universal Knob to select the desired value and push down the knob to
confirm. Press the Mem Depth softkey continually can also select the desired value.
The actual memory depth is displayed in the information area at the upper- right
corner of the screen. Since the oscilloscope of SDS1000X-E has two acquisition
memories, when only one channel is on, the maximal memory depth is up to 14
Mpts. SDS1000X-U only has one acquisition memory, when only one channel is on,
the maximal memory depth is up to 14 Mpts.
The maximum storage depth in single channel mode is twice that in dual channel
mode, as shown in the following table:

The relation of memory depth, sample rate and waveform length fulfills the
equation below:
Memory depth = sample rate (Sa/s) × waveform length (s/div × div)
Sampling Mode
The oscilloscope only supports real-time sample. In this mode, the oscilloscope
samples and displays waveform within a trigger event. The maximum real-time
sample rate is 1GSa/s.
Press the
RUN/STOP button to stop the sample, the oscilloscope will hold the last
display. At this point, you can still use the vertical control and horizontal control to

pan and zoom the waveform.
Interpolation Method
Under real-time sampling, the oscilloscope acquires the discrete sample values of
the waveform being displayed. In general, a waveform of dots display type is very
difficult to observe. In order to increase the visibility of the signal, the digital
oscilloscope usually uses the interpolation method to display a waveform.
Interpolation method is a processing method to “connect all the sampling
points”, and using some points to calculate the whole appearance of the
waveform. For real-time sampling interpolation method is used, even if the
oscilloscope in a single captures only a small number of sampling points. The
oscilloscope can use interpolation method for filling out the gaps between points,
to reconstruct an accurate waveform.
Press the
Acquire button on the front panel to enter the ACQUIRE Function menu;
then press the Interpolation softkey to select Sinx/x or X.
X: In the adjacent sample points are directly connected on a straight line. This
method is only confined to rebuild on the edge of signals, such as square
wave.
Sinx/x: Connecting the sampling points with curves has stronger versatility.
Sinx interpolation method uses mathematical processing to calculation results
in the actual sample interval. This method bending signal waveform, and
make it produce more realistic regular shape than pure square wave and pulse.
When the sampling rate is 3 to 5 times the bandwidth of the system.
Recommended Sinx/s interpolation method.

Acquisition Mode
The acquisition mode is used to control how to generate waveform points from
sample points. The oscilloscope provides the following acquisition mode: Normal,
Peak Detect, Average and Eres.
1. Press the
Acquire button on the front panel to enter the ACQUIRE function
menu;
2. Press the Acquisition softkey; then turn the Universal Knob to select the desired
acquisition mode and push down the knob to confirm. The default setup is
Normal.
Normal
In this mode, the oscilloscope samples the signal at equal time interval to rebuild
the waveform. For most of the waveforms, the best display effect can be obtained
using this mode. It is the default acquisition mode.

WWW.SIGLENT.COM
Peak Detect
In this mode, the oscilloscope acquires the maximum and minimum values of the
signal within the sample interval to get the envelope of the signal or the narrow
pulse of the signal that might be lost. In this mode, signal confusion can be
prevented but the noise displayed would be larger.
In this mode, the oscilloscope can display all the pulses with pulse widths at least
as wide as the sample period.

Figure 24 Pulse With 0.1% Duty, Peak Detect Mode
Average
In this mode, the oscilloscope averages the waveforms from multiple samples to
reduce the random noise of the input signal and improve the vertical resolution.
The greater the number of averages is, the lower the noise will be and the higher
the vertical resolution will be but the slower the response of the displayed
waveform to the waveform changes will be.
The available range of averages is from 4 to 1024 and the default is 16. When
Average mode is selected, press
Averages and turn the Universal knob or press the
softkey continually to set the desired average time.

sample rate of the digital converter is higher than the storage rate of the
acquisition memory.
Eres mode can be used on both single- shot and repetitive signals and it does not
slow waveform update. This mode limits the oscilloscope's real- time bandwidth
because it effectively acts like a low- pass filter.

Horizontal Format
Press the Acquire button on the front panel; then press the XY soft key to set the
XY(On) or YT(Off) mode. The default setup is YT.
YT
It is the normal viewing mode for the oscilloscope. In the Normal time mode, signal
events occurring before the trigger are plotted to the left of the trigger point and
signal events after the trigger plotted to the right of the trigger point.
XY
XY mode changes the display from a volt- versus- time display to a volt- versus-
volt display. Channel 1 amplitude is plotted on the X- axis and Channel 2 amplitude
is plotted on the Y- axis, the two channels will be turned on or off together.
You can use XY mode to compare frequency and phase relationships between two
signals. XY mode can also be used with transducers to display strain versus
displacement, flow versus pressure, volts versus current, or voltage versus
frequency.
The phase deviation between two signals with the same frequency can be easily
measured via Lissajous method. The figure below shows the measurement
schematic diagram of the phase deviation
According to
sinθ=A/B or C/D (wherein, θ is the phase deviation angle between the
two channels and the definitions of A, B, C and D are as shown in the figure above),
the phase deviation angle is obtained, that is: θ=±arcsin (A/B) or ±arcsin (C/D)

If the principal axis of the ellipse is within quadrant I and III, the phase deviation
angle obtained should be within quadrant I and IV, namely within (0 to π/2) or
(3π/2 to 2π). If the principal axis of the ellipse is within quadrant II and IV, the
phase deviation angle obtained should be within quadrant II and III, namely within
(π/2 to π) or (π to 3π/2).
X-Y function can be used to measure the phase deviation occurred when the signal
under test passes through a circuit network. Connect the oscilloscope to the circuit

Sequence Mode
Sequence is also a kind of acquisition mode, which does not display waveform
during sampling process. It improves the waveform capture rate, and the maximal
capture rate is 400,000 wfs/s. So it can capture the small probability event
effectively.
The oscilloscope runs and fills a memory segment for each trigger event. The
oscilloscope is busy acquiring multiple segments. The oscilloscope continues to
trigger until memory is filled, and then display the waveforms on the screen.
To use the sequence mode, the HORIZONTAL Format must be set to

Trigger
For trigger, you set certain trigger condition according to the requirement and
when a waveform in the waveform stream meets this condition, the oscilloscope
captures this waveform as well as the neighboring part and displays them on the
screen. For digital oscilloscope, it displays waveform continuously no matter
whether it is stably triggered, but only stable trigger can ensures stable display.
The trigger circuit ensures that every time base sweep or acquisition starts from the
input signal and the user-defined trigger condition, namely every sweep is
synchronous to the acquisition and the waveforms acquired overlap to display
stable waveform.
The following is the schematic diagram of the acquisition memory. As shown in the
figure below, the position of the trigger event is determined by the reference time
point and the delay setting.
Trigger setting should be based on the features of the input signal, thus you need
to have some knowledge of the signal under test to quickly capture the desired
waveform.
The oscilloscope provides abundant advanced trigger functions which can help
you to focus on the desired waveform details. These trigger types are edge, slope,
pulse, video, window, interval, dropout, runt, pattern and serial trigger. This
chapter will mainly introduce all these trigger functions which mentioned above in
details and tell you how to set the trigger conditions to capture desired waveform.

Trigger Source
The 2-channel oscilloscope’s trigger source includes analog channels,
EXT, EXT/5
and AC Line. The 4-channel oscilloscope’s trigger source includes analog channels
and AC Line.
Press the Setup button on the front panel to enter the TRIGGER function menu;
press the Source softkey and then turn the Universal Knob to select the desired
trigger source.
The current trigger source is displayed at the upper right corner of the screen.
Select channel with signal input as trigger source to obtain stable trigger.
Analog channel input:
Signals input from analog channels can all be used as the trigger source.
External trigger input:
External trigger source can be used to connect external trigger signal to the EXT
TRIG channel when all of the four channels are sampling data. The trigger signal
(such as external clock and signal of the circuit to be tested) will be connected to
EXT and EXT/5 trigger source via the [EXT TRIG] connector. EXT/5 trigger source
attenuates the signal by a factor of 5. It extends the trigger level. You can set the
trigger condition within the range of trigger level (-8 div to +8 div).
AC line:
The trigger signal is obtained from the AC power input of the oscilloscope. This kind
of signals can be used to display the relationship between signal (such as
illuminating device) and power (power supply device). For example, it is mainly
used in related measurement of the power industry to stably trigger the waveform
output from the transformer of a transformer substation.

Trigger Mode
The oscilloscope’s trigger mode includes auto, normal and single. Trigger mode
affects the way in which the oscilloscope searches for the trigger
After the oscilloscope starts running, the oscilloscope operates by first filling the
pre-trigger buffer. It starts searching for a trigger after the pre-trigger buffer is
filled and continues to flow data through this buffer while it searches for the trigger.
While searching for the trigger, the oscilloscope overflows the pre-trigger buffer
and the first data put into the buffer is first pushed out (First Input First Out, FIFO).
When a trigger is found, the pre- trigger buffer contains the events that occurred
just before the trigger. Then, the oscilloscope fills the post- trigger buffer and
displays the acquisition memory.
Press the
Auto, Normal and the Single buttons on the front panel to select the
desired trigger mode, and the corresponding status light will be lighted.
In the Auto trigger mode (the default setting), if the specified trigger conditions
are not found, triggers are forced and acquisitions are made so hat signal
activity is displayed on the oscilloscope.
The Auto trigger mode is appropriate when:
Checking DC signals or signals with unknown levels or activity.
When trigger conditions occur often enough that forced triggers are
unnecessary.
In the
Normal trigger mode, triggers and acquisitions only occur when the
specified trigger conditions are found. Otherwise, the oscilloscope holds the
original waveform and waits for the next trigger.
The Normal trigger mode is appropriate when:
You only want to acquire specific events specified by the trigger settings.
Triggering on an infrequent signal from a serial bus (for example, I2C, SPI,
CAN, LIN, etc.) or another signal that arrives in bursts. The Normal trigger
mode lets you stabilize the display by preventing the oscilloscope from
auto- triggering.
In the
Single trigger mode, the oscilloscope waits for a trigger and displays the
waveform when the trigger condition is met and then stops.
The Single trigger mode is appropriate when:

You can adjust the trigger level for a selected analog channel by turning the
Trigger Level Knob.
You can push the Trigger Level Knob to set the level to the waveform's 50% value
immediately. If AC coupling is used, pushing the Trigger Level knob sets the trigger
level to about 0 V.
The position of the trigger level for the analog channel is indicated by the trigger
level icon (if the analog channel is on) at the left side of the display. The value of
the analog channel trigger level is displayed in the upper- right corner of the

Note: trigger coupling has nothing to do with the channel coupling.
Trigger Coupling
Press the Setup button on the front panel to enter the TRIGGER function menu, and
then press the Coupling softkey and turn the Universal Knob or press the Coupling
softkey continually to select the desired coupling mode.
The oscilloscope provides 4 kinds of trigger coupling modes:
DC: allow DC and AC components into the trigger path.
AC: block all the DC components and attenuate signals lower than 8 Hz. Use AC
coupling to get a stable edge trigger when your waveform has a large DC
offset.
LF Reject: block the DC components and reject the low frequency components
lower than 2 MHz. Low frequency reject removes any unwanted low frequency
components from a trigger waveform, such as power line frequencies, etc. that
can interfere with proper triggering. Use LF Reject coupling to get a stable
edge trigger when your waveform has low frequency noise.
HF Reject: reject the high frequency components higher 1.2 MHz)

Note: adjust the time scale and horizontal position will not affect the holdoff
time.
Trigger Holdoff
Trigger holdoff can be used to stably trigger the complex waveforms (such as pulse
series). Holdoff time is the amount of time that the oscilloscope waits before
re-arming the trigger circuitry. The oscilloscope will not trigger until the holdoff
time expires.
Use the holdoff to trigger on repetitive waveforms that have multiple edges (or
other events) between waveform repetitions. You can also use holdoff to trigger on
the first edge of a burst when you know the minimum time between bursts.
For example, to get a stable trigger on the repetitive pulse burst shown below, set
the holdoff time to be >200 ns but <600 ns.
The correct holdoff setting is typically slightly less than one repetition of the
waveform. Set the holdoff to this time to generate a unique trigger point for a
repetitive waveform. Only edge trigger and serial trigger have holdoff option. The
holdoff time of the oscilloscope is adjustable from 80ns to 1.5s.
1. Press the
Stop button, and then use the Horizontal Position Knob and the
Horizontal Scale Knob to find where the waveform repeats. Measure this time
using cursors; then, set the holdoff.
2. Press the Setup button on the front panel to enter the TRIGGER function menu.
The default trigger type is edge.
3. Press the Holdoff Close softkey; and then turn the Universal Knob to set the
desired holdoff time.

Pattern Trigger
The Pattern trigger identifies a trigger condition by looking for a specified pattern.
The pattern trigger can be expanded to incorporate delays similar to other triggers.
Pattern durations are evaluated using a timer. The timer starts on the last edge
that makes the pattern “true”. Potential triggers occur on the first edge that
makes the pattern false, provided that the time qualifier criterion has been met.
The oscilloscope provides 4 patterns: logical AND, OR, NAND and NOR combination
of the channels. Each channel can set to low, high or invalid.
Do the following steps to set pattern trigger:
1. Press the
Setup button on the front panel to enter the TRIGGER function menu.
2. Press the Type softkey; turn the Universal Knob to select Pattern, and then push
down the knob to confirm.
3. Press each channel softkey to select Invalid, High or Low.
Low sets the pattern to low on the selected channel. A low is a voltage
level that is less than the channel's trigger level or threshold level.
High sets the pattern to high on the selected channel. A high is a voltage
level that is greater than the channel's trigger level or threshold level.
Don’t care sets the pattern to don't care on the selected channel. Any
channel set to don't care is ignored and is not used as part of the pattern.
However, if all channels in the pattern are set to Don’t care, the
oscilloscope will not trigger.
Adjust the trigger level for the selected analog channel by turning the
Trigger Level knob. Don’t care doesn’t need to set trigger level.

I2C Trigger
This part introduces the nine kinds of trigger conditions (Start, Stop, Restart, No Ack,
EEPROM, 7 Addr&Data, 10 Addr&Data and Data Length) and the methods of setting
them.
Trigger Conditions
Start Condition— the oscilloscope will be triggered when SDA signal transitions
from high to low while the SCL clock is high. If it is chosen as the condition of
trigger (including frame triggers), a restart will be treated as a “Start
condition”.
Stop Condition— the oscilloscope will be triggered when SDA transitions from
low to high while the SCL is high.
Restart— the oscilloscope will be triggered when another “Start condition”
occurs before a “Stop condition”.
No Ack— the oscilloscope will be triggered when SDA data is high during any
SCL’s ACK bit.
EEPROM — the trigger searches for EEPROM control byte (the value is 1010xxx)
on the SDA bus. And there is a Read bit and an ACK bit behind EEPROM. Using
Limit Range softkey to set the qualifier and Data1 softkey to set the data’s
value. If EEPROM’s data is greater(less, equal) than Data1, the oscilloscope will
be triggered at the edge of ACK bit behind Data byte. It’s unnecessary that the
Data byte musts follow the EEPROM.
7 Address & Data — the oscilloscope will be triggered when the following
conditions are satisfied.
The address’s length must be 7 bits and the address’s value is the same as
SDS1000X-E&SDS1000X-U User Manual
94
WWW.SIGLENT.COM
set value.
If you have set either Data1’s or Data2’s value, and the signal has a data is
the same as that value. If you have set both Data1’s and Data2’s value, the
signal should has two consecutive data, the first data’s value is Data1,
second data value is Data2.
(Note: If the data’s value is 0xXX, any data value will be matched)
10 Address & Data — the oscilloscope will be triggered when the following
conditions are satisfied.
The address’s length must be 10 bits and the address’s value is the same
as set value.
If you have set either Data1’s or Data2’s value, and the signal has a data is
the same as that value. If you have set both Data1’s and Data2’s value, the
signal should has two consecutive data, the first data’s value is Data1,
second data value is Data2.
(
Note: If the set value is 0xXX, any data value will be matched)
SDS1000X-E&SDS1000X-U User Manual

FFT Operation
FFT is used to compute the fast Fourier transform using analog input channels. FFT
takes the digitized time record of the specified source and transforms it to the
frequency domain. When the FFT function is selected, the FFT spectrum is plotted
on the oscilloscope display as magnitude in dBV versus frequency. The readout for
the horizontal axis changes from time to frequency (Hertz) and the vertical readout
changes from V to dB.
FFT operation can facilitate the following works:
Measure harmonic components and distortion in the device under test
Measure the characteristics of the noise in DC power
Analyze vibration
To display a FFT waveform:

Window
Applications and Characteristics
Rectangle
These are normally used when the signal is transient
(completely contained in the time-domain window) or known
to have a fundamental frequency component that is an integer
multiple of the fundamental frequency of the window. Signals
other than these types will show varying amounts of spectral
leakage and scallop loss, which can be corrected by selecting
another type of window.
Hanning
These reduce leakage and improve amplitude accuracy.
However, frequency resolution is also reduced.
Hamming
These reduce leakage and improve amplitude accuracy.
However, frequency resolution is also reduced.
Flat Top
This window provides excellent amplitude accuracy with
moderate reduction of leakage, but with reduced frequency
resolution.

To measure FFT waveform:
To make cursor measurements, press the Cursors button, and then press the Mode
softkey to select On to turn the cursors, Use the X1 and X2 cursors to measure
frequency values and the difference between two frequency values (ΔX). Use the
Y1 and Y2 cursors to measure amplitude in dB and difference in amplitude (ΔY).
You can find the frequency value at the first occurrence of the waveform maximum
by using the X at Max Y measurement.
Note:
Signals with DC components or deviation would cause error or deviation of
the FFT waveform components. To reduce the DC components, set the
Channel Coupling to AC.
To reduce the random noise and aliasing frequency components of repetitive
or single pulse, set the Acquisition of the oscilloscope to Average.
Note: please refer to the cursors chapter to obtain the method of using cursors.

Math Function Operation
The oscilloscope supports math function operation including differential (d/dt),
integral (∫dt) and square root ( ).
Differentiate
d/dt (differentiate) calculates the discrete time derivative of the selected source.
Where:
d = differential waveform
y = channel 1, 2, 3, or 4 data points
i = data point index
Δ t = point- to- point time difference
The
dx option under d/dt math function operation menu shows the point- to- point
time difference, and it ranges from 0.02div to 0.40div. “div” indicates the number
of the pixel points that each division has. The oscilloscope has 50 pixel points per
division. Take 0.2div as an example: 0.2*50=10. It means to calculate the ten point’s
discrete time derivative of the selected source, and the Δ t is the ten point’s point-
to- point time difference.

WWW.SIGLENT.COM
Figure 82 Difference Function Operation
You can use differentiate to measure the instantaneous slope of a waveform. For
example, the slew rate of an operational amplifier may be measured using the
differentiate function
Note: Because differentiation is very sensitive to noise, it is helpful to set
acquisition mode to Average.
SDS1000X-E&SDS1000X-U User Manual

WWW.SIGLENT.COM
Integrate
dt (integrate) calculates the integral of the selected source. You can use integrate
to calculate the energy of a pulse in volt- seconds or measure the area under a
waveform.
dt plots the integral of the source using the "Trapezoidal Rule". The equation is:
n
0i
i0n
ytcI
Where:
I = integrated waveform
Δt = point- to- point time difference
y = channel 1, 2, 3, or 4 data points
c
o
= arbitrary constant
i = data point index
The integrate operator provides an
Offset softkey that lets you enter a DC offset
correction factor for the input signal. Small DC offset in the integrate function input
(or even small oscilloscope calibration errors) can cause the integrate function
output to "ramp" up or down. This DC offset correction lets you level the integrate
waveform.

Cursors
Cursors are horizontal and vertical markers that indicate X- axis values and Y- axis
values on a selected waveform source. You can use cursors to make custom
voltage, time measurements on oscilloscope signals.
X Cursors
X cursors are vertical dashed lines that adjust horizontally and can be used to
measure time (when the source is FFT waveform, X cursors measure frequency).
X1 cursor is the left (default position) vertical dotted line; it can be moved to any
place of the screen.
X2 cursor is the right (default position) vertical dotted line; it can be moved to any
place of the screen.
Use the

displayed in the cursors box in the upper-left corner of the screen along with the
difference between X1 and X2 (△T) and 1/△T.
When set cursor type to X2-X1, use
Universal Knob will move the X1 and X2 cursors
together. The value under the menu option is the difference between the X1 and X2
cursors.
Y Cursors
Y cursors are horizontal dotted lines that adjust vertically and can be used to
measure voltage (V) or current (A). When the cursors source is the math function,
the unit will match the math function.
Y1 cursor is the top (default position) horizontal dotted line; it can be moved to any
vertical place of the screen.
Y2 cursor is the down (default position) horizontal dotted line; it can be moved to
any vertical place of the screen.

Digital Channels(Option)
This chapter describes how to use the digital channels of a Mixed-Single
Oscilloscope (MSO).
The digital channels are enabled on SDS1000X-E (4-channel scope) that have
installed the MSO activation license. As an external module, SLA1016 is
independent of the host, and has its own system, so it needs to be upgraded if
necessary.

Note:
There are two indicators on the side of the SLA1016, one is red (Power),
another is green (Ready)
The red indicator: If SLA1016’s power is normal, this indicator turns on,
or else it blinks or turns off.
The green indicator: When the SLA1016 is connect to the oscilloscope,
this indicator turns on for seconds then turns off, and then blinks, and
finally keeps the light on. When data is transferred between the
SLA1016 and the oscilloscope, the indicator blinks.
Connect the Digital Probes
1. If necessary, turn off the power supply to the device-under-test.
Turning off the power to the device-under-test prevents damage that
might occur if you accidentally short lines together while connecting
probes. You can leave the oscilloscope powered on because no voltage
appears at the probes.
2. Connect one of the digital probe cable ports to the digital channels connector
on the front panel of the SDS1000X-E, and the other one to the digital channels
connector of the digital probe.
The digital probe cable is keyed so you can connect it only one way. You
do not need to power-off the oscilloscope.
3. Connect a fly line to one of the digital probe ground pins, connect a grabber to
the fly line, and then connect the grabber to a ground trace/pin from the
device-under-test. The ground lead improves signal fidelity to the oscilloscope,
ensuring accurate measurements,
4. Connect a fly line to one of the digital probe digital channel pins; connect a
grabber to the fly line, and then connect the grabber to a node in the circuit you
want to test.
5. Repeat step 4 until you have connected all points of interest.

Pass/Fail Test
One way to verify a waveform's compliance to a particular set of parameters is to
use pass/fail testing. A pass/fail defines a region of the oscilloscope's display in
which the waveform must remain in order to comply with chosen parameters.
Compliance to the mask is verified point- by- point across the display.
The test results can be displayed on the screen as well as be declared through the
system sound or the pulse signal output from the

4. Press Set Vari-level to enter Vari-level editor. On the left side of the editor is a
spreadsheet which is used to specify the relationship between frequency and
amplitude. On the right side is an automatically generated stimulus voltage vs.
frequency plot.
5. The operation principle of Vari-level is simple. User specifies a series of joint,
which is defined by a given frequency and corresponding amplitude. In
between two adjacent joints, the frequency points and their corresponding
amplitude are calculated automatically by linear interpolation. The frequency
of the joints is sequential, so the frequency of the posterior joint is always
higher than the frequency of the anterior joint. And always, the first and the
last joint defines the start and stop frequency.
6. Press Profile and use the Universal Knob to select “Profile A”. As you can see,
up to 4 profiles can be saved.
7. In this example, I will demonstrate how to specify a Vari-level profile widely
used in testing power supply loop response. The profile is a 4-joint- polyline
with large stimulus amplitude in low frequency and small amplitude in high
frequency, and gradual amplitude in intermediate frequency.
8. Press Joints and use the Universal Knob to set the number of joint to 4.
9. Press Edit Table to activate the spreadsheet editor. When the spreadsheet
editor is activated, press Edit Table will cycle the cursor between frequency,

Troubleshooting
The commonly encountered failures and their solutions are listed below. When you
encounter those problems, please solve them following the corresponding steps. If
the problem remains still, please contact
SIGLENT Company as soon as possible.
1. The screen is still dark (no display) after power on:
1) Check whether the power is correctly connected.
2) Check whether the power switch is really on.
3) Check whether the fuse is burned out. If the fuse needs to be changed,
please use the specified fuse.
4) Restart the instrument after finishing the above inspections.
5) If it still does not work correctly, please contact
SIGLENT.
2. The signal is sampled but no waveform of the signal is displayed:
1) Check whether the probe is correctly connected to the signal connecting
wire.
2) Check whether the signal connecting wire is correctly connected to the BNC
(namely channel connector).
3) Check whether the probe is correctly connected to the item to be tested.
4) Check whether there are signals generated from the item to be tested (you
can connect the probe compensation signal to the problematic channel to
determine which has problem, the channel or the item to be tested).
5) Resample the signal.
3. The tested voltage amplitude is greater or lower than the actual value (note that this
problem usually occurs when probe is used):
Check whether the attenuation coefficient of the channel complies with the
attenuation ratio of the probe.
4. There is waveform display but not stable:
1) Check the trigger signal source: check whether the Source item at the
trigger panel complies with the signal channel actually used.
2) Check the trigger type: general signals should use “Edge” trigger and
video signal should use “Video” trigger. Only when the proper trigger
type is used, can the waveform be displayed stably.
3) Change the trigger holdoff setting.
5. No display after pressing Run/Stop:
Check whether the mode at the trigger panel (TRIGGER) is on “Normal” or
SDS1000X-E&SDS1000X-U User Manual
241
WWW.SIGLENT.COM
“Single” and whether the trigger level exceeds the waveform range. If yes,
set the trigger level to the middle or set the mode to “Auto”.
Note: using AUTO could automatically finish the above setting.
6. The display of waveform is ladder-like:
1) The horizontal time base might be too low. Increase the horizontal time
base to increase the horizontal resolution and improve the display.
2) If the display Type is “Vectors”, the lines between the sample points may
cause ladder-like display. Set Type to “Dots” to solve the problem.
7. Fail to connect PC through USB:
Check the IO Setting in Utility to make sure whether the setting in USB Device
matches the device currently connected. If needed, restart the oscilloscope.
8. The USB storage device cannot be recognized:
1) Check whether the USB storage device can work normally.
2) Make sure whether the USB interface can work normally.
3) Make sure that the USB storage device being used is flash storage type.
This oscilloscope does not support hardware storage type.
4) Restart the instrument and then insert the USB storage device to check it.
5) If the USB storage device still cannot be used normally, please contact
SIGLENT.
