WARNING: Do not operate the oscilloscope in an explosive
atmosphere or wet and damp conditions.

The design of the instrument has been verified to conform to EN
61010-1 safety standard per the following limits:Installation (overvoltage) Category: II (Mains Supply Connector)

Degree of Pollution: IIDegree of Protection: IP20

Note:
Installation (Overvoltage) Category II refers to the local
distribution level, which is applicable to equipment connected to themains supply (AC power source).

Degree of Pollution II refers to a working environment which is dry
and non-conductive pollution occurs. Occasional temporaryconductivity caused by condensation is expected.

CAUTION: Protect the display touch screen of the scope fromexcessive impact.

CAUTION: Do not exceed the maximum specified front panel
terminal (CH1, CH2, CH3, CH4, EXT) voltage levels. Refer toSpecifications for more details.

CAUTION: Do not connect or disconnect probes or test leads
while they are connected to a voltage source.

2.3 Cooling Requirements
This instrument relies on forced air cooling with internal fans andventilation openings. Care must be taken to avoid restricting the
airflow around the apertures (fan holes) at each side of the scope.
To ensure adequate ventilation it is required to leave a 15 cm (6inch) minimum gap around the sides of the instrument.

CAUTION: Do not block the ventilation holes located on bothsides of the scope.

CAUTION: Do not allow any foreign matter to enter the scopethrough the ventilation holes, etc.

2.4 AC PowerThe instrument operates with a single-phase, 100 to 240 Vrms (+/-10%)
AC power at 50/60 Hz (+/-5%), or single-phase 100 - 120 Vrms (+/-10%)
AC power at 400Hz (+/-5%).

No manual voltage selection is required because the instrument
automatically adapts to line voltage.

Depending on the type and number of options and accessories (probes,
PC port plug-in, etc.), the instrument can consume up to 100 W of

13 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

power.

Note: The instrument automatically adapts to the AC line input within
the following ranges:
Voltage Range:

90 - 264 Vrms

90 - 132 Vrms

Frequency Range:

47 - 63 Hz

380 - 420 Hz

2.5 Power and ground connections
The instrument includes a grounded cord set containing a molded
three-terminal polarized plug and a standard IEC320 (Type C13)
connector for making line voltage and safety ground connection. The
AC inlet ground terminal is connected directly to the frame of the
instrument. For adequate protection against electrical shock hazard,
the power cord plug must be inserted into a mating AC outlet
containing a safety ground contact. Use only the power cord specified
for this instrument and certified for the country of use.

Warning: Electrical Shock Hazard!
Any interruption of the protective ground conductor within or
outside of the scope or disconnection of the safety groundterminal creates a hazardous situation.
Intentional interruption is prohibited.

The position of the oscilloscope should allow easy access to thesocket. To make the oscilloscope completely power off, unplug the
instrument power cord from the AC socket.

14 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

The power cord should be unplugged from the AC outlet if the scope is
not to be used for an extended period of time.

CAUTION: The outer shells of the front panel terminals (CH1,
CH2, CH3, CH4, EXT) are connected to the instrument’s chassis
and therefore to the safety ground.

2.6 Calibration
The recommended calibration interval is one year. Calibration should
be only performed by qualified personnel.

2.7 Cleaning
Clean only the exterior of the instrument, using a damp, soft cloth.
Do not use chemicals or abrasive elements. Under no circumstances

Vertical Scale: The scale of each grid in the vertical direction. For
example, when the vertical scale is 1.00 V/div, the full scale of theoscilloscope is 1.00 V/div*8 div=8 V.

Vertical Offset: The offset of the channel in the vertical direction.
When the vertical offset is 0, the channel offset indicator is
located in the middle of the vertical axis.

Probe Attenuation Factor: Set the probe attenuation factor to matchthe actual attenuation of the probe. The oscilloscope automaticallycalculates the vertical scale according to the probe attenuation
factor. For example, the vertical scale of the oscilloscope is
100mV/div with 1X attenuation, and 1V/div if the attenuation factor
is changed to 10X. When inserting a standard 10X passive probe with aprobe sense terminal, the oscilloscope will automatically set thefactor to 10X.

with DC offset, such as power ripple.


GND: The channel is grounded by an internal switch. GND couplingis used to observe the zero offset error of the analog channels or
determine the source of noise in the waveform (from signal or fromoscilloscope itself)

Bandwidth Limit
Full bandwidth will pass through signals with high-frequency
components, but it also means that noise with high-frequency
components can pass through. When the frequency component of a signal
is very low, better signal-to-noise ratios (SNR) can be obtained byenabling one of the available bandwidth limits. The SDS2000X Plus
provides two bandwidth limit options: 20 MHz and 200 MHz. The
bandwidth limit effectively lowers the input frequency response of
the input to the selected limit value.

Probe Attenuation
The SDS2000X Plus provides 1X, 10X, 100X and custom probe attenuation
factor options. The custom values can be between 10-6~106. The

64 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

oscilloscope will automatically convert the vertical scale according
to the current probe attenuation factor. For example, the verticalscale of the oscilloscope under 1X attenuation is 100 mV/div, and thevertical scale will be automatically set to 1 V/div if the probe
attenuation is changed to 10X. If a standard probe with readout terminal
is connected, the oscilloscope will automatically set the probe
attenuation to match the probe.

Label
Users can set the label text for channels. Open the label setting
dialog box to select the source, customize the label text, and set thedisplay. The source can be C1~C4, F1~F2, and RefA~RefD. The length ofthe label is limited to 20 characters. The characters beyond thislength will not be displayed. When the “Display” option is set to“on”, the label will be displayed on the right side of the channel
offset indicator.

Impedance

1 MΩ: When a passive probe with high impedance is connected, theimpedance must be set to 1 MΩ, otherwise the signal will not be
detected.

50 Ω: Suitable for high-frequency signals transmitted through 50
Ω coaxial cables and can minimize the amplitude distortion caused
by impedance mismatching.

Unit
Voltage unit "V" or current unit "A”. When using the current probe,
the unit should be set to "A".

Deskew
Due to the skew between channels, cables or probes, the delay ofsignals passing through different measurement paths may be
inconsistent. For example, two coaxial cables with a 1-inch
difference in length could introduce a skew of more than 100 ps. In
some scenarios (e.g. measuring the setup/hold time between clock anddata), it may be necessary to compensate the skew between channels.

The method of compensation: Probe the same signal simultaneously
using two channels (including the cables or probes that you intend touse for measurements) and adjust the deskew parameter of one channel
until the waveforms of the two channels observed on the screen

Acquisition: See the section " Acquisition" for details.

Memory Depth: The maximum memory depth that can be supported. According
to the formula "acquisition time = sample points x sample interval",setting a larger memory depth can achieve a higher sample rate for agiven time base, but more samples require more processing time,degrading the waveform update rate. With 200 Mpts memory depth,

76 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

SDS2000X Plus can still run at full sample rate (2 GSa/s) even when
set to the 10 ms/div timebase.

Note: The memory depth here is the upper limit of the memory space
allocated by the oscilloscope. The actual sample points are related tothe current timebase and may be less than memory depth. The actual
sample points information can be obtained in the timebase descriptorbox (see the section "Timebase and Trigger" for details).

The maximum memory depth in single-channel mode is 2 times that of thedual-channel mode, as the following table:

Single-channel mode (interleaving mode): Only one of C1/C2 is turned
on, and only one of C3/C4 is turned on.
Dual-channel mode (non-interleaving mode): Both C1/C2 are turned on,
or both C3/C4 are turned on.

Interpolation -- At small timebase settings, the number of original
points on the screen may be less than the number display pixels in thegrid area, so interpolation is necessary to display a continuous

waveform. For example, at 1 ns/div timebase and 2 GSa/s sample rate,
the number of original points is 20, but the grid area includes 1000
horizontal pixels. In this case, the oscilloscope needs to interpolate
the original points by 50.


X: Linear interpolation, the simplest way of interpolation,connects two original points with a straight line.

Sinc: Sin(x)/x interpolation, the original point is interpolated
according to the Nyquist reconstruction formula, which has a goodtime-domain recovery effect for sine wave. But for step signals/fastrise times, it will introduce false overshoot due to the Gibbs
phenomenon.

X Interpolation

Sinc Interpolation

Acq mode -- "Fast" is the default setting. The SDS2000X Plus provides
a very high waveform update rate in fast mode. "Slow" mode will slow
down the waveform update on purpose.

Resolution -- The vertical resolution. "8-bits" is the default setting.
In "10-bits" mode, the vertical resolution is 4x better, while thebandwidth is limited to about 100 MHz.

14.2.2Acquisition

The acquisition mode is used to determine how to acquire and process
the signal.

Normal: The oscilloscope samples the signal with an equal time interval.
For most waveforms, the best display effect can be obtained using thismode.

Peak: Peak detect mode. The oscilloscope acquires the maximum andminimum values of the signal within the sample interval so that thepeak (maximum – minimum) in the interval is obtained. This mode iseffective to observe occasional narrow pulses or spurs with a low
sample rate, but the noise displayed is larger. In peak mode, theoscilloscope will display all pulses with a pulse width longer than
400 ps.

In the following example, a narrow pulse sequence with a pulse widthof 3.4 ns and a period of 200 Hz is sampled at 2 MSa/s sample rate innormal mode and peak mode. As we can see, because the sample interval(500 ns) is much larger than the pulse width (3.4 ns), it is difficult
to capture the narrow pulses in normal mode, but peak mode can ensurethat each pulse is captured.

14.2.3Roll Mode

Press the Roll button on the front panel to enter roll mode. In thismode, the waveform moves across the screen from right to left, similar
to a strip chart recorder. The horizontal delay control of the waveform
will be disabled when roll mode is active. It only operates at timebase
values of 50 ms/div and above.

If you would like to stop the display in Roll mode, press the Run/Stopbutton. To clear the display and restart an acquisition in Roll mode,press the Run/Stop button again.

14.2.4

Sequence

Touch Acquire>Sequence to recall sequence dialog box.
A. Turn on or off sequence
B. Set the segment

Sequence mode is a fast acquisition mode, which divides the memory
depth to multiple segments (up to 90,000), each of which stores asingle shot. In sequence mode, the oscilloscope only acquires andstores data without processing and displaying, until the specified
segments are acquired. As a result, the dead time between trigger
events is minimized, thus greatly improving the waveform update rate.

81 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

If sequence mode is enabled, the display will not update until all of
the sequences have been acquired. The SDS2000X Plus can achieve aminimum 2μs trigger interval in Sequence mode, corresponding to a
waveform update rate of 500,000 wfm/s.

After the acquisition is finished, the oscilloscope will map all thesegments together to the screen. If you need to view and analyze eachframe separately, history mode will help (see the section " History"
for details). History mode provides timestamp labels for each segment.

In addition to minimizing the dead time, another advantage of Sequencemode is that it can capture and record rare events over long time
periods. The oscilloscope can capture multiple events that satisfy thetrigger conditions, ignoring the periods of no interest between
adjacent events, thus maximizing the use of waveform memory. You can
use the full accuracy of the acquisition timebase to measure selected
segments.

15 Trigger
15.1 Overview
The oscilloscope only acquires waveforms of interest (i.e. the ones
that satisfy the trigger condition) and aligns all trigger events atthe trigger position to form a stable waveform display. The trigger
is one of the most important features of an oscilloscope since we canonly analyze a signal that we are able to trigger in a reliable andstable manner.

The trigger position is movable on the display. The following diagramshows the structure of the acquisition memory. The acquisition memory
is divided into pre-trigger and post-trigger buffers and the boundary
between them is the trigger position. Before the trigger event arrives,theoscilloscope

fills

the

pre-trigger

bufferfirst,

andthencontinuously updates it in FIFO mode until the trigger event arrives.
After the trigger event, the data fills the post-trigger buffer. Whenthe post-trigger buffer is full, an acquisition is completed.

SDS2000X Plus Series Digital Oscilloscope User Manual

Arm: The pre-trigger buffer is not full, and the oscilloscope does not
respond to any trigger events.
Ready: The pre-trigger buffer is full, and the oscilloscope is waiting
for the trigger event.
Trig’d: A trigger event is detected and the oscilloscope starts tofill the post-trigger buffer.

Trigger settings should be based on the features of the input signal.
For example, a sine wave with a repeatable period can be triggered on
the rising edge; for capturing hazards in a combinational logic circuit,the pulse trigger can be set. You need to have some knowledge of thesignal-under-test to quickly capture the desired waveform.

15.3 Trigger Level
Both analog and digital triggers must have a correct trigger levelvalue. The oscilloscope judges whether a waveform satisfies the trigger
condition when it crosses the trigger level. If it does, the crossing
time is the trigger position. In the following figure, the trigger
condition is set as to capture a rising edge. When the signal withpositive slope crosses the trigger level, the trigger condition issatisfied and the time point the signal crosses the level is the trigger
position.

In some special trigger, the system will automatically set the trigger
level, such as using AC Line as the trigger source.

15.4 Trigger Mode
The trigger mode determines how the oscilloscope acquires waveforms.

Auto：An internal timer triggers the sweep after a preset timeout
period if no trigger has been found so that the oscilloscope

94 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manualcontinuously updates the display whether a trigger happens or not.
Auto mode is suitable for unknown signals or DC signals.
Note: In Auto mode, if the signal satisfies the trigger conditions
but cannot trigger the oscilloscope stably, it may be that interval
between two trigger events exceeds the timeout period. Try Normal
mode in this case.

Normal：Triggers and acquisitions only occur when the trigger conditions
are met. Otherwise, the oscilloscope holds the last waveform on thedisplay and waits for the next trigger. Normal mode is suitable foracquiring:

Only events specified by the trigger settings

Rare events

Single：Captures and displays a single frame which satisfies the trigger
conditions, and then stops. The following trigger events are ignored
until the Single acquisition is restarted. Single-mode is suitable for:One-shot events or periodic signals, such as power-on\off
waveforms on a power railRare events

Window Trigger

Window trigger is similar to edge trigger, except that it provides anupper and a lower trigger level. The instrument triggers when the input
signal passes through the upper level or the lower level.

There are two kinds of window types: Absolute and Relative. They havedifferent trigger level adjustment methods. Under the Absolute window
type, the lower and the upper trigger levels can be adjusted separately.
The relative window provides adjustment for the Center value to set
the window center and a Delta value to set the window range. In this106 / 342



If the lower and the upper trigger levels are both within the
waveform amplitude range, the oscilloscope will trigger on bothrising and falling edges.



If the upper trigger level is within the waveform amplitude
range while the lower trigger level is out of the waveform
amplitude range, the oscilloscope will trigger on the risingedge only.

15.7 Holdoff
Holdoff is an additional condition for triggers and can be used tostabilize the triggering of complex waveforms (such as a pulse series).
It can be set to a time or number of events.

Holdoff by Time
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 theminimum time between bursts.

For example, to achieve a stable trigger on the repetitive pulses shownin the figure below set the holdoff time (t) to 200 ns < t < 600 ns.

Holdoff by Event
The holdoff event is the number of events that the oscilloscope counts
before re-arming the trigger circuitry. The oscilloscope will not
trigger until the counter tracking holdoff events reaches the set value.
115 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

In the following figure, the holdoff event is set to 3, and the signal
is triggered on the fourth edge.

Parameter Start Holdoff On defines the initial position of holdoff.

Acq Start-- The initial position of holdoff is the first time point
satisfying the trigger condition. In the example above, each holdoff
starts from the first rising edge of the pulse sequence.

Last Trig Time--The initial position of holdoff is the time of thelast trigger. In the example above, the last trigger position is at
the second rising edge of the pulse sequence and the second holdoff
starts from that point.

15.8 Trigger Coupling
The coupling setting of a trigger is only valid when the trigger sourceis C1~C4, EXT or EXT/5.


DC: All of the signal’s frequency components are coupled to thetrigger circuit for high-frequency bursts or where the use of AC
coupling would shift the effective trigger level.



AC: The signal is capacitively coupled. DC levels are rejected. See
the datasheet for details of the

cut-off

frequency.

HFR: Signals are DC coupled to the trigger circuit and a low-passfilter network attenuates high frequencies (used for triggering on
low frequencies). See the datasheet for details of the
off



cut-

frequency.

LFR: The signal is coupled through a capacitive high-pass filter
network, DC is rejected and low frequencies are attenuated. For
stable triggering on medium to high-frequency signals. See thedatasheet for details of the cut-off

frequency.

15.9 Noise Reject
Noise Reject adds additional hysteresis to the trigger circuitry. By
increasing the trigger hysteresis, the noise immunity becomes betterbut the trigger sensitivity degrades.

The CS signal should be set to correct CS Type, including CS, ~CS, andClock Timeout.
CS – Active high. The CS signal needs a complete rising edge on
the screen to be regarded as active.

~CS – Active low. The ~CS signal needs a complete falling edge on
the screen to be regarded as active.



Clock Timeout – It is not necessary to specify the source and thethreshold level for the CS signal. The only parameter for the CS
signal is the timeout Limit, which is the minimum time that theclock signal must be held idle for before the oscilloscope acquires
valid data. This setting is suitable for the case where the CS
signal is not connected, or the number of oscilloscope channels is
insufficient (such as two-channel oscilloscopes).

18.1 Overview
The SDS2000X Plus features a strong automatic measurement list. These
parameters can be automatically measured without cursors and include
common measurements such as rise time, fall time, peak-peak, and period.
The SDS2000X Plus can also measure multiple channels at the same time,showing up to 5 parameter measurements with statistics while in the M1
display mode and up to 12 parameters in the M2 mode. If you wish toview more parameters on a specified channel, then the "Simple" modecan be employed. For measuring waveform of interest in a time gate,the "Gate" function is suggested.

Some parameter measurements (such as the mean) may be a value generated
by all the data in a frame.

Some parameter measurements (such as

period) accumulate all measurements in a frame, but the displayed value
is always the first value. If you want to know the distribution ofmultiple parameters in one frame, you should use the statistics
function.

18.9 Gate
Sometimes the user may want to measure parameters for a certain
specified time range of the signal and ignore signal parts that lie
outside of that range. In this case, the Gate function can be helpful.

Touch Gate in the measure dialog box, then two
horizontal cursors A and B will appear in thegrid area.

The gate setting dialog box will be

displayed on the right.
Gate cursors A and B are used to define therange of time for parameter measurements. The
oscilloscope only measures the parameters ofthe data between A and B, ignoring the data
outside the range.
The setting of gate cursors is similar to thatof ordinary cursors. See " Select and Move
Cursors" for details.

SDS2000X Plus Series Digital Oscilloscope User Manual

19.2.1

Average

The oscilloscope accumulates multiple waveform frames and calculates
the average as the result. If a stable trigger is available, theresulting average has a random noise component lower than that of asingle-shot record. The more frames that are accumulated, the lower
the noise is.

214 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

Note: Average acquisition is only valid for periodic signals, and it
is important to ensure that the waveform is triggering in a stable way
when using average mode.

19.2.2ERES

The oscilloscope filters the sample, which rejects noise in the highfrequency domain, so the signal-to-noise ratio (SNR) is improved. As
a result, the effective number of bits (ENOB) of the oscilloscope isenhanced.

215 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

ERES operation does not require the signal to be periodic, nor does it
require stable triggering, but due to the digital filtering, the system
bandwidth of the oscilloscope will degrade when acquiring data in ERES
mode. The higher the enhanced bits, the lower the bandwidth. The
following table shows the relationship between ERES bits and bandwidth:

19.3 Algebra
The SDS2000X Plus can perform algebra operations including differential(d/dt), integral (∫dt) and square root (√)

19.3.1

Differential

The differential (d/dt) operator is used to calculate the derivativeof the selected source. It is always used to measure the instantaneous
slope of the waveform, such as the slew rate of an operational amplifier.
The differential equation is:di =y (i + dx) - y(i)dxWhere:
d = Differential result
y = Values of source datai = Data point index
dx = Differential interval

The range of “dx” in the d/dt menu is 2~20. The measurement units
are point and the corresponding time difference range is 0.02~0.20 div.
“div” indicates the number of the pixel points that each division
has and is 100 for the SDS2000X Plus. If dx = 10 points, the timedifference is:0.01*10 = 0.1 div
Then the differential operator calculates the "average slope in 10

217 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

points" of the selected source and dx represents the time difference
between the 10 sampled points.

dx = 2dx = 6

Note: Differentiation is sensitive to noise.

19.3.2IntegralIntegral operation integrates the waveforms on the screen or within
the specified gate.

Setting Offset in the integral menu provides an approach to correct
the DC offset of the source. Small DC offsets in the input signal (oreven small offset errors of the oscilloscope itself) may cause theintegral output waveform to "ramp" up or down, as shown below:

Integral without Offset

218 / 342

Integral with Offset

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

In addition, the integral operation can be performed within a specified
gate. Touch Gate area in the math dialog box, and enable Gate function,then set Gate A and Gate B to define the gate. The setting of the gatecursors is similar to that of normal cursors. See " Select and Move
Cursors" for details.

19.3.3

Square RootSquare root （√） calculates the square root of the selected source.
If the waveform value is negative (the waveform is below the groundlevel), the result is displayed as zero.

219 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

19.3.4Absolute

Absolute（|x|）calculates the absolute value of the selected trace.

19.3.5Sign

In mathematics, the sign function or signum function (from signum,
Latin for "sign") is an odd mathematical function that extracts thesign of a real number.

220 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

The sign function of a real number x is defined as follows:Sign(x) = -1

if x < 0,= 0

if x = 0,= 1

if x > 0.

19.3.6 Exp/Exp10
The exponential operation includes the exponential operation 𝑒 𝑥 basedon constant e and the exponential operation 10𝑥 based on 10.

For example: y(x) = 𝑒 𝑥 .

221 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

19.3.7 Ln/Lg
Logarithmic operation includes logarithm base e (ln) and logarithm base
10 (lg). In logarithmic operation, if the waveform value is negative(the waveform is below the ground level), the result is displayed aszero.

For example: F1 = 𝑒 𝑥 , where x is the trigonometric wave function. F2= ln (F1).

according to the selected interpolation method and interpolation
coefficient. Touch Acquire ＞ Interpolation to set the interpolation
method, and the interpolation coefficient can be set to 2, 5, 10 or 20.

FFT sample rate (Sa): FFT operation results present the first
Nyquist zone (DC ~ Sa/2) of the frequency spectrum. Be aware that
the FFT sample rate may be inconsistent with the sample rate in thetime domain. Assuming the max points is set to 2 Mpts:✓ When the number of points in the time domain, N, is less than
2 Mpts, the FFT takes the number which is an integer power of
2 closest to N. In this case, the FFT sample rate = sample ratein the time domain.
✓ When N is greater than 2 Mpts, FFT first decimates N by D andthen takes the first 2 Mpts for the calculation. In this case,
the FFT sample rate = sample rate in time domain/D.
For example, in the case of sample rate in the time domain is
1 GSa/s and the number of samples is 10 Mpts, the FFT firstdecimates the samples by 4, to 2.5 Mpts, and then takes thefirst 2 Mpts to calculate the spectrum. In this example, FFT
sample rate = 1 GSa/s ÷ 4 = 250 MSa/s.

25.5 Switching Loss
Switch loss analysis can be used to calculate the power dissipated in

Deskew Calibration
A relatively small skew can cause a large measurement error of switching
loss, especially during the on phase when the voltage is close to zeroand the non-on phase when the current is close to zero. This is atypical oscilloscope dynamic range limitation when trying to measure
weak voltage and (or) current in the presence of relatively large
switching voltage and (or) current.

To correct the skew between the oscilloscope channels or probes, thedeskew procedure should be performed once initially, and re-run when
any part of the hardware setup changes (for example, a different probe,
different oscilloscope channel, etc.) or when the ambient temperaturechanges. The deskew procedures by using the DF2001A deskew fixture is
as followed.

25.11 PSRR
The power supply rejection ratio (PSRR) test is used to determine how
the regulator suppresses ripple noise in different frequency ranges.
The oscilloscope controls the arbitrary waveform/function generator to
output a sweep signal, which is used to introduce ripple into the DC
voltage transmitted to the voltage regulator. Measure the AC RMS ratio
of input to output, and plot the relationship between the ratio andfrequency. The background noise of the oscilloscope is higher than thatof the network analyzer, and the sensitivity is lower than that of the
network analyzer, so the PSRR measured by the oscilloscope is difficult
to exceed -60 dB. The PSRR test is generally acceptable for sampling
the overall PSRR behavior of the power supply under test.

The configuration of PSRR is the same as that of the bode plot, see
the chapter " Bode Plot" for details.

26 Bode Plot
26.1 Overview
The SDS2000X Plus supports an automatic bode plot function. Thisfunction provides a frequency response curve of the device-under-test
as well as the interface for output sweep parameter control and data
display settings. At this time, either the built-in waveform generator
or one of a SIGLENT SDG series arbitrary function generators aresupported. During the sweep, the oscilloscope configures the generator
output frequency and amplitude and then compares the input signal tothe output of the DUT. Gain (G) and phase (P) are measured at eachfrequency and plotted on the frequency response bode plot. When theloop response analysis is complete, you can move the markers on thechart to see the gain and phase values measured at each frequency point.
You can also adjust the scale and offset settings for the amplitude
and phase plots.

Auto Steps: In this mode, the adjustment can only be performed with
CH1 of the oscilloscope. Connect the output of AWG to CH1 of theoscilloscope, press Auto, and the AWG will start to automaticallyadjust. The scope will display “Zero adjust completed!” when theadjustment is done.



Manual Steps: The AWG can be manually calibrated through any channelon the oscilloscope. Take CH2 as an example:
1. Connect the output of AWG to CH2, open CH2, set it to DC
coupling, turn on bandwidth limit, and set the probe attenuation
to 1X.
2. Set the vertical scale of CH2 to a small scale such as 1mV/div.
Turn on measure and set the parameter to Mean of CH2.

To Default Key
The oscilloscope provides two options for the default setting. When
the Default Type is set to “Factory”, the factory default setting
will be recalled by pressing the Default button on the front panel;
When the Default Type is set to “Current”, the last setting saved by
the “To Default Key” operation will be recalled by pressing theDefault button on the front panel.

Bin2CSV Tool
The mini tool is used to convert stored binary files to CSV format forviewing with a spreadsheet program. This is ideal when collecting large
datasets. For a waveform frame with deep memory such as 200 Mpts, tosave directly as a CSV file will take long time and will occupy a large
amount of memory on a USB storage device. It’s recommended to savethe data as binary file and then convert it to CSV file on a computer.

32 Troubleshooting
The commonly encountered failures and their solutions are listed below.
When you encounter those problems, please solve them following thecorresponding steps. If the problem remains still, please contact
SIGLENT 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 tobe changed, please contact SIGLENT timely and return the
instrument to the factory for replacement by the maintenancepersonnel authorized by SIGLENT.
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 tobe tested.
339 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

5) Resample the signal.

3. The tested voltage amplitude is greater or lower than the actual
value (Note that this problem usually occurs when a probe isused):
1) Check whether the attenuation coefficient of the channel
complies with the attenuation ratio of the physical probe.
2) Disconnect the oscilloscope from the external signal and doa self-cal.

4. There is a waveform displayed but it is not stable. The waveformmoves across the display over time:1) Check the trigger signal source: Check whether the source
item at the trigger panel complies with the signal channel
actually used.
2) Check whether it is a "false wave”: When the signal
frequency is very large (more than half of the sample rate),
it is easy to appear a "false wave". At this point, a small
time base should be set to make the sample rate more than 2times of the signal frequency.
3) Check the trigger type: General signals should use “Edge”
trigger and video signals should use “Video” trigger. Only
when the proper trigger type is used, can the waveform be
displayed stably.
4) Change the trigger holdoff setting.

340 / 342

WWW.SIGLENT.COM

SDS2000X Plus Series Digital Oscilloscope User Manual

5. No display after pressing Run/Stop:
Check whether the mode at the trigger panel (TRIGGER) is on“Normal” or “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 AutoSetup could automatically finish the above
setting.

6. Touch screen does not respond to touch operation:
1) Check whether the Touch button backlight on the front panel
is lighted up. If not, the touch screen is not turned on.
Press the button to enable the touch screen
2) Restart the instrument.

7. 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 a flash
storage type (USB memory sticks, thumb drives, etc..). Thisoscilloscope does not support hardware storage types likestand-alone disk drives.
4) Make sure that the U disk system format is FAT32.
5) Restart the instrument and then insert the USB storage device
to check it.
6) If the USB storage device still cannot be used normally,please contact SIGLENT.
