Trigger coupling:
Coupling mode of the current trigger source. It is only valid when the trigger source
is C1~C8, EXT, or EXT/5.
DC: All the signal’s frequency components are coupled to the trigger 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-pass filter network attenuates high
frequencies (used for triggering on low frequencies). See the datasheet for details of the cut-off
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 the
datasheet for details of the cut-off frequency.
Trigger mode
Auto: The oscilloscope will sweep without a set trigger. An internal timer triggers the sweep after
a preset timeout period so that the display refreshes continuously. This is helpful when first
analyzing unknown signals. Otherwise, Auto functions the same as Normal when a trigger
condition is found.
Normal: Sweeps only if the input signal meets the trigger condition. Otherwise, it continues to
display the last acquired waveform.
Single: Stops the acquisition and displays the last acquired waveform.
Force: Force an acquisition, regardless of whether the input signal meets the trigger conditions or
not.
Trigger level
: The source voltage level or levels that mark the threshold for the trigger to fire. Trigger
levels specified in Volts normally remain unchanged when the vertical gain or offset is modified.
Trigger type:

Coupling
DC: All of the input signal frequency components are passed to the display.
AC: The signal is capacitively coupled. DC signal components are rejected. See the datasheet for
details of the cut-off frequency.AC coupling is suitable for observing AC signals with DC offset,
such as power ripple.
SDS6000L User Manual
int. s i g l en t . c o m 55
GND: The channel is grounded by an internal switch. GND coupling is used to observe the zero-
offset error of the analog channels or determine the source of noise in the waveform (from the
signal or from the oscilloscope itself)
Bandwidth Limit
Full bandwidth passes through signals with high-frequency components, but it also means that noise
with high-frequency components can pass through. When the frequency component of the signal is
very low, better signal-to-noise ratios (SNR) can be obtained by turning on a bandwidth limit. The
SDS6000L provides two hardware bandwidth limit options: 20 MHz and 200 MHz
Probe Settings
The SDS6000L provides 1X, 10X, 100X, and custom probe attenuation factor options. The custom
values can be between 10-6~106. The oscilloscope will automatically convert the vertical scale
according to the current probe attenuation factor. For example, the vertical scale of the oscilloscope
under 1X attenuation is 100 mV/div, and the vertical scale will be automatically set to 1 V/div if the
probe attenuation is changed to 10X. If a standard probe with a readout terminal is connected, the
oscilloscope will automatically set the probe attenuation to match the probe.
The Probe Check option is provided to quickly check if the probe is correctly compensated. Connect
the probe as in section “Probes” and click Probe > Probe Check , then operate according to the
prompt.
If an active probe is connected, click Probe to show the information and setup of the active probe.
Below is the information for an SAP1000 probe.

Apply to
With this setting, some common functions such as Trigger, FFT, Simple Measure, Cursor, Search,
DVM, Histogram, Mask Test, Counter, and AWG can be quickly applied to the selected channel. Once
a function is specified, it will switch directly to the function menu and automatically set that channel as
the source.
Impedance
1 MΩ: When a passive probe with high impedance is connected, the impedance 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 or active probes.
This 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 of signals 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
SDS6000L User Manual
58 i n t . s i g l e n t . c o m
time between the clock and data), it may be necessary to compensate for the skew between channels.
The method of compensation: Probe the same signal simultaneously using two channels (including the
cables or probes that you intend to use for measurements) and adjust the deskew parameter of one
channel until the waveforms of the two channels observed on the screen coincide horizontally.
Before deskew
After deskew
Note:
When the channel with delay compensation is the trigger source, the
trigger delay indicator will not change at any time when the deskew value
changes.

Interpolation
-- At small timebase settings, the number of original points on the screen may be less
than the number of display pixels in the grid area, so interpolation is necessary to display a continuous
waveform. For example, at 1 ns/div timebase and 5 GSa/s sample rate, the number of original points
is 50, but the grid area includes 1250 horizontal pixels. In this case, the oscilloscope needs to
interpolate the original points by 25.
SDS6000L User Manual
68 i n t . s i g l e n t . c o m
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 good time-domain recovery effect for a sine wave. But for step
signals / fast rise times, it will introduce false overshoot due to the Gibbs phenomenon.
X Interpolation
Sinc Interpolation
Acq mode:
"Fast" is the default setting. The SDS6000L provides a very high waveform update rate in
fast mode. "Slow" mode will slow down the waveform update on purpose.
Memory Depth
: The 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 a given time base, but more samples require more processing time, degrading the waveform update
rate.

11.2.2 Acquisition
The acquisition mode is used to determine how to acquire and process the signal.
Normal:
The oscilloscope samples the signal with equal time intervals. For most waveforms, the best
display effect can be obtained using this mode.
Peak:
Peak detect mode. The oscilloscope acquires the maximum and minimum values of the signal
within the sample interval so the peak (maximum-minimum) in the interval is obtained. This mode is
effective to observe occasional narrow pulses or spurs with a low sample rate, but the noise displayed
is larger. In peak mode, the oscilloscope will display all pulses with a pulse width longer than 200 ps.
In the following example, a narrow pulse sequence with a pulse width of 3.4 ns and a period of 200 Hz
is sampled at a 5 MSa/s sample rate in normal mode and peak mode. As we can see, because the
sample interval (200 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 ensure that each pulse is captured.

Average:
The oscilloscope accumulates multiple waveform frames and calculates the average as the
result. If a stable trigger is available, the resulting average has a random noise component lower than
that of a single-shot record. The more frames that are accumulated, the lower the noise is. For the
SDS6000L, average processing is implemented by the hardware engine, so it can still maintain a high
waveform update rate when the acquisition mode is set to average.

Note:
Average acquisition is only valid for periodic signals, and it is important
to ensure that the waveform is triggering stably when using average mode.
ERES:
In this mode, the oscilloscope digitally filters the sampling points, which can reduce the
broadband random noise on the input signal and improve the signal-to-noise ratio, to improve the
effective resolution (ENOB) of the oscilloscope. The ERES processing of the SDS6000L is realized by
the hardware engine, so it can still maintain a high waveform refresh rate when ERES is turned on.

11.2.3 Memory Management
Memory Management controls how the instrument stores the acquired samples.
Auto: The default acquisition setting. After setting the maximum memory in the Auto mode, the
oscilloscope automatically adjusts the sample rate and memory depth according to the time base. The
adjustment principle is to follow the formula:
Sample rate = number of samples/time of acquisition
Where the time of acquisition is the time corresponding to the full display (i.e. 10 horizontal divisions).
Note:
The maximum memory here is the upper limit of the memory space
allocated by the oscilloscope. The actual sample points are related to the
current time base and may be less than memory depth. The actual sample
points information can be obtained in the timebase descriptor box (see the
section "Timebase and Trigger" for details).
Fixed Sample Rate: The sample rate is fixed as set, and the oscilloscope automatically adjusts
memory depth according to the time base. The time of acquisition is the time corresponding to the full
display (i.e. 10 horizontal divisions).
Fixed Memory: The memory depth is fixed as set, and the oscilloscope automatically adjusts the
sample rate according to the time base. With a small time scale (such as 1 ns/div) the memory depth
is beyond the time of the full display, so it needs to zoom out the acquired frame for viewing the
complete frame in Stop mode.
Note:
When the status is Run, the scope only processes the data on the
display, which means measure, math, decode, search, etc. only analyzes the
data on the display. This is identical to the "Auto" memory management
mode.

11.2.4 Roll Mode
Click Acquire > Roll to enter roll mode. In this mode, 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, click Acquire > Run/Stop . To clear the display
and restart an acquisition in Roll mode, perform Acquire > Run/Stop again.
Note:
Zoom is only supported after Stop in Roll mode.
11.2.5 Sequence
Click Acquire > Sequence to recall the 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 into multiple segments
(up to 80,000), each of which stores a single shot. In sequence mode, the oscilloscope only acquires
and stores data without processing and displaying it until the specified segments are acquired. As a
result, the dead time between trigger events is minimized, thus greatly improving the waveform update
rate. If sequence mode is enabled, the display will not update until all of the sequences have been
acquired. The SDS6000L can achieve a minimum 1.3 us trigger interval in Sequence mode,
corresponding to a waveform update rate of 750,000 wfm/s.
After the acquisition is finished, the oscilloscope will map all the segments together to the screen. If
you need to view and analyze each frame separately, history mode will help (see the section "History"
for details). History mode provides timestamp labels for each segment.
SDS6000L User Manual
74 i n t . s i g l e n t . c o m
In addition to minimizing the dead time, another advantage of Sequence mode is that it can capture
and record rare events over long periods. The oscilloscope can capture multiple events that satisfy the
trigger 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.
Example:
Input a pulse sequence with a period of 50 ms to C1. The rise time of the pulse is 2 ns, the fall time is
100 ns, the pulse width is 108 ns, and amplitude is 1.6 Vpp. Perform Acquire > Auto Setup .
Set the coupling mode of C1 to DC50Ω, and vertical scale to 500 mV/div, vertical offset to 0. Set the
trigger level to 0.

11.2.6 ESR
Each channel of the SIGLENT SDS6000L Oscilloscope employs a 5 GSa/s analog-to-digital-converter
(ADC). After each ADC, a 2x interpolation process is applied that provides a 10 GSa/s ESR option for
the users. The data flow and corresponding spectrum are shown in the figure below:

SDS6000L User Manual
int. s i g l en t . c o m 77
The 2x interpolation implemented is a classic sinx/x up-sampling processed by a high-speed Field
Programmable Gate Array (FPGA) in real-time. The following figure shows the frequency response of
the Finite Impulse Response (FIR) digital filter used in the interpolation. From the frequency response,
we can see it has no attenuation at fmax = 2 GHz, and ~70 dB attenuation at 5 GHz – fmax = 3 GHz,
which provides enough alias suppression for signals in the operating bandwidth. The aliasing
associated with signals above 2 GHz is minimized by the fast roll-off of the analog front end.
Higher measurement precision
The ADC sample rate to bandwidth ratio in the SDS6000L is 2.5:1. That means for a 2 GHz input there
are 2.5 samples/period. Without any extra interpolation, the measurements on vertical waveform
elements such as Maximum, Minimum, and Peak-peak will introduce considerable error at highfrequency input. The figure below shows an example in which a 500 MHz signal is sampled at 5 GSa/s:
Error on vertical measurement introduced by insufficient sampling
SDS6000L User Manual
78 i n t . s i g l e n t . c o m
Interpolation can significantly reduce this kind of error. Below is the same signal with an identical
sample rate but followed by the 2x interpolation technique. From this figure, we can see points inserted
between the raw data in the top/base area are closer to the real top/base of the analog input, which
reduces the error.
Error on vertical measurement after 2x interpolation
Higher ERES bandwidth
High-resolution acquisition in the SDS6000L enhances the vertical resolution but doing so results in a
decrease in the available bandwidth. The higher the resolution, the lower the bandwidth. The bandwidth
as a function of resolution and sample rate is shown in the table below:
Table: Bandwidth specifications of the SDS6000L in ERES acquisition mode

13 Trigger
13.1 Overview
The oscilloscope only acquires waveforms of interest (i.e. the ones that satisfy the trigger condition)
and aligns all trigger events at the trigger position to form a stable waveform display. The trigger is one
of the most important features of an oscilloscope since we can only analyze a signal that we can trigger
reliably and stably.
The trigger position is movable on the display. The following diagram shows 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, the oscilloscope fills
the pre-trigger buffer first, and then continuously updates it in FIFO mode until the trigger event arrives.
After the trigger event, the data fills the post-trigger buffer. When the post-trigger buffer is full, an
acquisition is completed.
Below is the definition of the states in the process of filling the acquisition memory:
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 to fill 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 the signal-under-test to
quickly capture the desired waveform.

13.3 Trigger Level
Both analog and digital triggers must have a correct trigger level value. 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 a rising edge.
When the signal with a positive slope crosses the trigger level, the trigger condition is satisfied and the
time point the signal crosses the level is the trigger position.
In some special triggers, the system will automatically set the trigger level, such as using AC Line as
the trigger source.

13.4 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 continuously 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 the display and waits for the next trigger. Normal mode is
suitable for acquiring:
Only events specified by the trigger settings
Rare events
Single:
Captures and displays a single frame that 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
Force:
The oscilloscope triggers regardless of whether the input signal meets the trigger conditions or
not.

For interlaced scanning signals (such as NTSC, PAL, 1080i/50, 1080i/60, and Custom), when the
synchronization mode is "Select", the specified line and the specified field can be selected to trigger.
The following table shows the corresponding relations between line and field for all video standards
(except for Custom)
Standard

To gain familiarization with the video trigger, try these two examples:
Trigger on a specific line of video (NTSC standard)
Use “Custom” to trigger video signals
Trigger on a Specific Line of Video
Video trigger requires that any analog channel can be used as the trigger source with a synchronization
amplitude greater than 1/2 grid. The example below sets to trigger on Field 1, Line 22 using the NTSC
video standard.
1. Open the trigger menu.
2. In the trigger menu, click Type , and select "Video".
3. Click the Source and select CH1 as the trigger source.
4. Click the Standard and select the "NTSC".
5. Click the Sync and select the "Select" to make the Field and Line optional, then select "1"
in the "Field", and set the "Line" to "22" by using the mouse wheel or the virtual keypad.

Trigger on a Specific Line of Video (NTSC)
Use "Custom" to Trigger Video Signals
Custom video trigger supports video signals with frame rates of 25, 30, 50, and 60 Hz respectively,
and the specified row is within the range of 300 to 2000. The following describes how to trigger a
"Custom" video signal.
1. Open the trigger menu.
2. In the trigger menu, click the Type , and select "Video".
3. Click the Source and select CH1 as the trigger source.
4. Click the Standard and select the "Custom".
5. Click the Custom Setting to open the custom setting menu and click the Interlace to
select the required interlace ratio (assuming that the interlace ratio is 8:1). Then set the frame
rate and select the number of lines and the number of fields.
6. Click the Sync to select the synchronization mode for the input signal:
a) Select the "Any" mode, and the signal can be triggered on any line that meets the trigger
condition.
b) Select the "Select" mode, then set the specified line and the specified field to trigger the
signal. Assuming that the "Field" is set to 8, you can select any field from 1 to 8, and
each field can choose any line from 1 to 100.

13.5.6 Window Trigger
The window trigger is similar to the edge trigger, except that it provides an upper 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 have different 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 the Delta value to set the window range. In this mode, the lower and the upper trigger levels
always move together.
If the lower and the upper trigger levels are both within the waveform amplitude range, the
oscilloscope will trigger on both rising 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 rising edge only.
If the lower trigger level is within the waveform amplitude range while the upper trigger level
is out of the waveform amplitude range, the oscilloscope will trigger on the falling edge only.
To set window trigger via the Absolute window type
Refer to "Adjust Upper/Lower Level" in the section "Slope Trigger".
