Enable the Channel

The SHS800X/SHS1000X provides 2 analog input channels and each channel
shares the same vertical control system. Since the vertical system setting
methods of each channel is the same, this chapter uses CH1 as an example to
introduce the setting method of the vertical system.

Connect the signal to the CH1 channel connector; and then press the CH1 button
in the vertical control area (VERTICAL) on the front panel to enable CH1.

The channel setting menu and the channel information bar are displayed at the
bottom of the screen.

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.

23

SHS800X&SHS1000X User Manual

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 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. Press the Vertical Scale button to adjust the vertical scale (V to
increase the scale and mV to reduce).

The scale information in the channel information bar at the bottom of the screen
will change accordingly during the adjustment process. The adjustable range of
the vertical scale is related to the probing ratio currently set. By default, the probe
attenuation factor is 1X and the adjustable range of the vertical scale is from 2
mV/div to 100 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
must be greater than twice the maximum frequency f
reconstruct the signal without aliasing.

Sample Rate

The maximum sample rate of the oscilloscope is 1GSa/s. The actual sample rate
of the oscilloscope is determined by the horizontal scale. Press the Horizontal
Scale Button to adjust the sample rate.

The actual sample rate is displayed in the information area at the bottom right
corner of the screen.

The effect of low sampling rate on the waveform:

1. Waveform Distortion: when the sample rate is too low, some waveform

details are lost and the waveform displayed is quite different from the actual
signal.

Pulse disappeared

2. Waveform Confusion: when the sample rate is lower than twice the actual

signal frequency (Nyquist Frequency), the waveform frequency reconstructed
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

reconstructed from the sample data cannot reflect all the actual signal
information.

Bandwidth and Sample Rate

An oscilloscope's bandwidth is typically described as the lowest frequency at
which the input sinusoidal signal is attenuated by 3 dB (- 30% amplitude error).

Under the bandwidth frequency, the required sampling rate is fS = 2fBW according
to the sampling theory. However, the theory assumes that there are no frequency
components above f
requires a system with an ideal brick wall frequency response.

(fBW in this case) in the system, which means that it

In fact, digital signals have frequency components above the fundamental
frequency (a square wave is composed of a sine wave of the fundamental
frequency and numerous odd harmonics), and generally, for oscilloscopes with a
bandwidth of 500 MHz and below, the system has a Gaussian frequency
response.

Therefore, the sampling frequency of the oscilloscope should be four or more
times the bandwidth frequency: fS = 4fBW. In this way, there is less aliasing, and
the components in the aliasing area are attenuated a lot.

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 bottom right
corner of the screen. Since the oscilloscope has two acquisition memories, when
only one channel is on, the maximal memory depth is up to 12 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 sampling. 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, and 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.

The 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 the interpolation method to fill out the gaps between points
and 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 a
square wave.

 Sinx/x: Connecting the sampling points with curves has stronger versatility.

Sinx interpolation method uses mathematical processing to calculate results
in the actual sample interval. This method bending signal waveform, and
make it produce a more realistic regular shape than pure square wave and
pulse. When the sampling frequency is 3 to 5 times the bandwidth frequency
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 intervals 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.

Figure 18 Acquisition System

44

SHS800X&SHS1000X User Manual

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 signal's envelope 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 20 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 and the higher the
vertical resolution will be. Still, 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.

Note: “Average” and “ERES” mode use different averaging methods. The
former uses “Waveform Average” and the latter uses “Dot Average”.

ERES

This mode uses a kind of ultra-sample technique to average the neighboring
points of the sample waveform to reduce the random noise on the input signal
and generate much smoother waveforms on the screen. ERES mode is generally
used when the sample rate of the digital converter is higher than the storage rate
of the acquisition memory.

ERES mode can be used on single-shot and repetitive signals and does not slow
waveform updates. 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- versus­volt 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)

49

SHS800X&SHS1000X User Manual

WWW.SIGLENT.COM

If the principal axis of the ellipse is within quadrant I and III, the phase deviation
angle obtained should be within quadrants I and IV, namely within (0 to π/2) or
(3π/2 to 2π). Suppose the principal axis of the ellipse is within quadrant II and IV.
In that case, the phase deviation angle obtained should be within quadrant II and
III, namely within (π/2 to π) or (π to 3π/2).

The X-Y function can be used to measure the phase deviation that occurred when
the signal under test passes through a circuit network. Connect the oscilloscope
to the circuit to monitor the input and output signals of the circuit.

Sequence Mode

Sequence is also a kind of acquisition mode, which does not display waveform
during the 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 YT.

Trigger

For trigger, you set certain trigger condition according to the requirement. When
a waveform in the waveform stream meets this condition, the oscilloscope
captures this waveform and the neighboring part and displays them on the
screen. Still, the digital oscilloscope displays waveform continuously no matter
whether it is stably triggered, but only stable trigger can ensure stable display.
The trigger circuit ensures that every time base sweep or acquisition starts from
the input signal and the user-defined trigger condition. 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 mentioned above in
detail and tell you how to set the trigger conditions to capture the desired
waveform.

Trigger Mode

The SHS800X/SHS1000X’s trigger mode includes auto, normal, single and Force.
Trigger mode affects how 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
before the trigger. Then, the oscilloscope fills the post- trigger buffer and
displays the acquisition memory.

Press the Trigger Setup button and Mode softkey to select the desired trigger
mode.
 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, displays the

waveform when the trigger condition is met, and stops.

The Single trigger mode is appropriate when:

56

SHS800X&SHS1000X User Manual

WWW.SIGLENT.COM

 To capture single event or a periodic signal.
 To capture burst or other unusual signals.

 In the Force trigger mode, when the trigger condition is not met, it will be

force triggered after the frame is acquired. The trigger status in the upper left
corner of the screen will be displayed as "FStop".

Trigger Level

Trigger level and slope define the trigger point,

You can adjust the trigger level for a selected analog channel by pressing the
Trigger Level button and turning the Universal Knob.

You can push the Universal Knob to set the level to the waveform's 50% value
immediately. If AC coupling is used, pushing the Universal 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.

Note: trigger coupling has nothing to do with the channel coupling.

Trigger Coupling

Press the Trigger Setup button on the front panel to enter the TRIGGER function
menu. 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 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

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 repetitive waveforms with 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 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 button and the

Horizontal Scale button to find where the waveform repeats. Measure this
time using cursors; then, set the holdoff.

2. Press the Trigger Setup button 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.

Noise Rejection

Noise Reject adds additional hysteresis to the trigger circuitry. By increasing the
trigger hysteresis band, you reduce the possibility of triggering on noise.
However, this also decreases the trigger sensitivity so that a slightly larger signal
is required to trigger the oscilloscope.

Window Trigger

Windows trigger provides a high trigger level and a low trigger level. The
instrument triggers when the input signal passes through the high trigger level or
the low trigger level.

There are two kinds of window types: Absolute and Relative. They have different
trigger level adjustment methods. Under Absolute window type, the lower and
the upper trigger levels can be adjusted respectively via the Level knob; under
Relative window type, adjust the Center value to set the window center; adjust
the Delta value to set the window range, 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
edge.

 Suppose the upper trigger level is within the waveform amplitude range

while the lower trigger level is out of the waveform amplitude range. In that
case, the oscilloscope will trigger on rising edge only.

 Suppose the lower trigger level is within the waveform amplitude range

while the upper trigger level is out of the waveform amplitude range. In that
case, the oscilloscope will trigger on falling edge only.

To set window trigger via Absolute window type:

1. Press the Trigger Setup button on the front panel to enter the TRIGGER

function menu.

2. Press the Type softkey; then use the Universal Knob to select Window and

push down the knob to confirm.

3. Press the Source softkey; turn the Universal Knob to select CH1 or CH2 as the

trigger source.

4. Press the Window Type softkey to select Absolute.

5. Press the Lower Upper softkey to select Lower or Upper trigger level; then

press the Trigger Level button and turn the Universal Knob to adjust the
