Chapter 2 To Set the Vertical System

DS8000-R series provides four analog input channels (CH1-CH4), and each channel is equipped with an independent vertical control system. The setting methods for the vertical systems of the four channels are the same. This chapter takes CH1 as an example to introduce the setting method for the vertical system. For this oscilloscope, only CH1 is enabled by default.

RIGOL Chapter 2 To Set the Vertical System
2-2 DS8000-R User Guide

To Enable or Disable the Analog Channel

Enable the analog channel:
Connect a signal to the channel connector of CH1, and then click the CH1 label at the bottom part of the screen to enable CH1. Then, CH1 label is illuminated in yellow. At this point, the channel setting menu is displayed at the right section of the screen and the channel is activated. The channel status label at the bottom of the screen is shown in the figure below.
The information displayed in the channel status label is related to the current channel setting but irrelevant with the on/off status of the channel. After the channel is turned on, modify the parameters such as the vertical scale, horizontal time base, trigger mode, and trigger level according to the input signal for easy observation and measurement of the waveform.
If CH1 is enabled but not activated, the channel status label is shown in the following figure. To activate the channel, click the channel number in the channel status label or the channel label at the left side of the screen.
Disable the analog channel:
If the setting menu of the channel that needs to be disabled (the current channel is activated) is displayed at the right section of the screen, click the channel status label to disable the channel. If the setting menu of the channel that needs to be disabled is not displayed at the right section of the screen, first open the setting menu of the channel to be disabled (activate the channel), then click the channel status label to disable the channel. For example, if CH1 and CH2 are enabled, and CH2 channel setting menu is displayed on the screen, then if you need to disable CH1, first activate CH1, and then click the CH1 channel status label displayed on the externally connected screen to disable CH1. If CH1 is disabled, the channel status label is shown in the following figure.

To Adjust the Vertical Scale

Vertical scale indicates the voltage value per grid in the vertical axis of the screen. It is often expressed in V/div. While you adjust the vertical scale, the display amplitude of the waveform would enlarge or reduce. The scale information of the channel status label (e.g. as shown in the following figure) at the lower section of the screen
Chapter 2 To Set the Vertical System RIGOL
DS8000-R User Guide 2-3
would change accordingly.
The adjustable range of the vertical scale is related to the currently set probe ratio and input impedance. By default, the probe ratio is 1X and the input impedance is 1 MΩ. In this case, the adjustable range of the vertical scale is from 1 mV/div to 10 V/div.
When CH1 is turned on, you can adjust the vertical scale with the following method: Click the channel status label at the bottom of the screen. The following window is
displayed. Click on the icon at the right side of the Scale input field to decrease or increase (i.g. compress or enlarge the waveforms). You can also click the
Scale input field to input a specific value with the displayed numeric keypad.

Vertical Expansion

Click the channel status label at the bottom of the screen. In the channel menu, click More, then click Expand continuously to select "Center" or "GND".
Center: when the vertical scale is changed, the waveform will be expanded or
compressed around the screen center.
GND: when the vertical scale is changed, the waveform will be expanded or
compressed around the signal ground level position.

To Adjust the Vertical Offset

Vertical offset indicates the offset of the signal ground level position of the waveform from the screen center in the vertical direction. Its unit is consistent with the currently selected amplitude unit (refer to "Amplitude Unit"). When adjusting the vertical offset, the waveforms of the corresponding channel moves up and down. The vertical offset information (as shown in the following figure) in the channel status label at the bottom of the screen will change accordingly.

The adjustable range of the vertical offset is related to the current input impedance, probe ratio, and vertical scale.
When CH1 is turned on, you can adjust the vertical offset with the following method: Click the channel status label at the bottom of the screen. The following window is
displayed. Click on the icon at the right side of the Offset input field to decrease or increase the offset. You can also click the Offset input field to input a specific value with the displayed numeric keypad.

Channel Coupling

The undesired signals can be filtered out by setting the coupling mode. For example, the signal under test is a square waveform with DC offset.
When the coupling mode is "DC": the DC and AC components of the signal under
test can both pass the channel.
When the coupling mode is "AC": the DC components of the signal under test
are blocked.
When the coupling mode is "GND", the DC and AC components of the signal
under test are both blocked.
Click Coupling in the channel setting menu to select the coupling mode. The available coupling modes include DC, AC, and GND. The current coupling mode is displayed in the channel status label at the bottom of the screen, as shown in the figure below.
DC AC GND
Note:
When the input impedance is set to "50 Ω", the channel coupling is set to DC
coupling by force, and the Coupling menu is grayed out and cannot be modified.
When the coupling mode is "AC", the input impedance is set to 1 MΩ by force,
Value Input Field Decrease Increase
Chapter 2 To Set the Vertical System RIGOL
DS8000-R User Guide 2-5
and the Impedance menu is grayed out and cannot be modified.

Bandwidth Limit

DS8000-R series supports the bandwidth limit function. Setting the bandwidth limit can reduce the noises in the displayed waveforms. For example, the signal under test is a pulse with high frequency oscillation.
When the bandwidth limit is disabled, the high frequency components of the
signal under test can pass the channel.
When you enable the bandwidth limit and limit it to 20 MHz, 250 MHz, or 500
MHz, the high frequency components found in the signal under test that are greater than 20 MHz, 250 MHz, or 500 MHz are attenuated.
Note: The bandwidth limit is different for different models.
Click the channel status label and select the desired bandwidth limit in the CH1 setting menu. When the bandwidth limit is enabled, the character "B" will be displayed in the channel status label at the bottom of the screen, as shown in the figure below.
The bandwidth limit that you select is based on the input impedance of your oscilloscope model, as shown in Table 2-1.
Table 2-1 Bandwidth Limit
Input Impedance of the Oscilloscope
Available Bandwidth Limit
50 Ω
DS8104-R/DS8204-R: 20 M DS8034-R: 20 MHz, 250 MHz
1 MΩ
DS8104-R/DS8204-R: 20 MHz, 250 MHz, 500 MHz; DS8034-R: 20 MHz, 250 MHz
Note: Bandwidth limit can not only reduce the noise, but also can attenuate or
eliminate the high frequency components of the signal.

Probe Ratio

DS8000-R series allows you to set the probe attenuation manually. To obtain the correct measurement results, you must set the probe ratio properly. By default, the probe ratio is 1X.
Click the CH1 channel status label to open the setting menu of CH1. Then, click Attenuation to select the desired probe ratio. The probe ratio values available are

Note: After the oscilloscope auto-recognized certain probes with a fixed attenuation
ratio, the probe ratio will also be auto recognized. You do not have to set it manually.

Input Impedance

To reduce the circuit load between the oscilloscope and the circuit under test, this oscilloscope provides two input impedance modes: 1 MΩ (default) and 50 Ω.
1 MΩ: The input impedance of the oscilloscope is very high, and the current
flowed from the circuit under test can be ignored.
50 Ω: makes the oscilloscope match the device whose input impedance is 50 Ω.

Note: This parameter is related to the instrument model and the current horizontal
time base setting. The larger the horizontal time base is, the larger the setting step will be.

Offset Cal

When you use an oscilloscope to make actual measurements, a small offset that arises from the temperature drift of the component or external environment disturbance may occur on the zero-cross voltage of the channel, which will affect the measurement results of the vertical parameters. DS8000-R allows you to set an offset calibration voltage for calibrating the zero point of the corresponding channel, so as to improve the accuracy of the measurement results.
Note: If the zero-cross voltage of the channel has a larger amplitude offset that
exceeds the adjustable offset calibration range, please perform self-calibration for the instrument manually to ensure the measurement accuracy. For details, refer to descriptions in "Self-calibration".
Click the CH1 channel status label to enter the CH1 setting menu. Click More Offset Cal, then use the pop-up numeric keypad or scroll with the mouse to set the offset calibration value.

To Adjust the Horizontal Time Base

Horizontal time base, also called the horizontal scale, refers to the time of each grid in the horizontal direction of the screen. It is usually expressed in s/div. The adjustable range of the horizontal time base is from 200 ps/div to 1 ks/div.
While you change the horizontal time base, the displayed waveforms of all channels are expanded or compressed horizontally relative to the current selected horizontal reference baseline (refer to "Horizontal Expansion"). The horizontal time base at the upper-left corner of the screen will be changed accordingly, as shown in the figure below.
You can adjust the horizontal time base with the following methods:
Click the horizontal time base label at the top of the screen. The following
window is displayed. Click on the icon at the right side of the Scale input field to decrease or increase the scale (i.g. enlarge or compress the waveforms). You can also click the Scale input field to input a specific value with the displayed numeric keypad.
You can click on the function navigation icon to open the function navigation. Then click Acquisition Fine to enable or disable the fine adjustment of the horizontal time base.
Coarse adjustment: adjusts the horizontal time base of the waveforms of all
channels at 1-2-5 step within the adjustable range.
Fine adjustment: adjusts the horizontal time base of the waveforms of all
channels with a minor step value within the adjustable range.

To Adjust the Horizontal Position

Horizontal position, also called trigger position, refers to the trigger point position of the waveforms of all channels in the horizontal direction relative to the screen center. When the waveform trigger point is at the left (right) side of the screen center, the

Timebase Mode

DS8000-R series supports three available time base modes: YT mode, XY mode, and ROLL mode. By default, the time base mode is YT.
Click the function navigation icon at the lower-left corner of the externally connected screen to open the function navigation menu. Click the acquisition icon
to open the acquisition setting menu. Click Timebase Mode to select the
desired time base mode.

YT Mode

In this mode, the Y axis represents voltage, and the X axis represents time.
Note: Only when this mode is enabled, can delayed sweep be turned on. In this
mode, when the horizontal time base is equal to or greater than 200 ms/div, the instrument enters slow sweep mode. For details, refer to descriptions for slow sweep in "ROLL Mode".

XY Mode

In this mode, both the X axis and the Y axis represent the voltage. The mode changes the display from voltage-time display mode to voltage-voltage display. You can use the Lissajous method to measure the phase deviation of the two input signals whose frequencies are the same. The following figure shows the measurement schematic diagram of phase deviation.
Figure 4-1 Measurement Schematic Diagram of Phase Deviation
According to sin=A/B or C/D, is the phase deviation angle between the two

DS8000-R User Guide 4-3
channels. The definitions of A, B, C, and D are shown in the above figure. The phase deviation angle is obtained, that is:
=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 /2 to
π) or (π to 3π/2).
The XY 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 to monitor the input and output signals of the circuit.
Application example: measures the phase deviation between the input signals of two channels.
Use Lissajous method
1. Connect one sine signal to CH1, and then connect another sine signal (with the
same frequency and amplitude as the previous one but a 90° phase deviation from the previous one) to CH2.
2. In the Web Control page, click Auto at the right side of the operation interface.
After you select "XY" mode, click the label at the top of the screen to adjust the horizontal timebase for obtaining a proper sample rate to get a better view of Lissajous graph for observation and measurement.
3. Click the channel label of CH1 and CH2 at the bottom of the screen respectively
to adjust their vertical scale and offset to make the signals easy to observe. Then, a circle, as shown in the figure below, should be displayed.
4. Observe the measurement result shown in the figure above. According to the
measurement schematic diagram of the phase deviation (as shown in Figure 4-1), A/B(C/D)=1. Thus, the phase deviation angle of the two channel input
RIGOL Chapter 4 To Set the Sample System
4-4 DS8000-R User Guide
signals is =arcsin1=90°.
Note:
The maximum sample rate in XY mode is 2.5 GSa/s. In this mode, CH1 and CH2
are forced to be enabled; CH3 and CH4 are forced to be disabled. Generally, a longer sample waveform can ensure better display effect of Lissajous figure. But due to the limitation of the memory depth, you have to reduce the waveform sample rate to acquire a longer waveform (refer to the introduction in "Memory Depth"). Therefore, during the measurement, reducing the sample rate properly can achieve better display effect of Lissajous figure.
The following functions are disabled in XY mode:
"Delayed Sweep", "To Select the Display Type", "Scale", "Protocol Decoding", "Pass/Fail Test", "To Trigger the Oscilloscope", and "Waveform Recording & Playing".

ROLL Mode

In this mode, the waveform scrolls from right to left to update the display. The available range of the horizontal scale is from 200 ms to 1 ks. Click the function navigation icon to select the Acquisition icon, then click More Auto ROLL to select "ON". The system automatically enters the ROLL mode, and slow sweep mode is disabled.
Note:
If the current delayed sweep is enabled, then when you enable the ROLL mode,
the delayed sweep is disabled automatically. When you re-enable the "YT" mode, the delayed sweep will be re-enabled.
The following functions cannot be set in ROLL mode:
"To Adjust the Horizontal Position" (available when the oscilloscope is in "Stop" operating status), "Delayed Sweep", "To Trigger the Oscilloscope",
"Protocol Decoding", "Pass/Fail Test", "Waveform Recording & Playing", and "To Set the Persistence Time".
Slow Sweep
It is similar to the ROLL mode. In YT mode, when the horizontal time base is set to 200 ms/div or smaller, the instrument enters the "slow sweep" mode, in which the instrument first acquires the data at the left of the trigger point and then waits for a trigger event. After the trigger occurs, the instrument continues to finish the waveform at the right of the trigger point. When observing the low-frequency signal in the slow sweep mode, it is recommended that you set "Channel Coupling" to "DC".

DS8000-R supports the following four acquisition modes: Normal, Average, Peak, and High Resolution. By default, the acquisition mode is Normal.
Click on the function navigation icon to open the navigation function. Then, click
Acquisition Acquisition to select the desired acquisition mode.

Normal

In this mode, the oscilloscope samples the signal at a specified fixed time interval to rebuild the waveform. For most of the waveforms, using this mode can produce the optimal display effects.

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. Greater number of averages can lower the noise and increase the vertical resolution; while at the same time, it will slow the response of the displayed waveform to the waveform changes.
When you select "Average" mode, click Averages and use the numeric keypad or scroll with the mouse to set the desired number of averages. When the average count value is not in Nth power-of-2, a prompt message "Truncation average error" is displayed. At this time, a value that is smaller than the one you input and the closest to the Nth power-of-2 will be input automatically. For example, if you input 9 with the numeric keypad, the average count will be input 8 automatically.
The number of averages can be set to 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, or 65536. By default, it is 2.

Figure 4-2 Waveforms before Averaging
Figure 4-3 Waveforms after 128 Times of Averaging

Peak

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 that might be lost. In this mode, signal aliasing can be prevented, but the noise displayed would be larger.
In this mode, the oscilloscope can display all the pulses whose pulse widths are at least the same as the sample period.

High Resolution

This mode uses an over-sample technique to average the neighboring points of the sample waveform. This reduces the random noise on the input signal, generates a
Chapter 4 To Set the Sample System RIGOL
DS8000-R User Guide 4-7
much smoother waveform on the screen. This is generally used when the sample rate of the digital converter is greater than the storage rate of the acquisition memory.
Note:
The "Average" and "High Res" modes use different averaging methods. The
former uses "Multi-sample Average" and the latter uses "Single-sample Average".
In "High Res" mode, the oscilloscope improves the measurement accuracy at
the cost of bandwidth. Each time the sampling rate changes, a window displaying the current bandwidth appears at the lower-left corner of the screen.
In "High Res" mode, the highest waveform refresh rate mode is not supported.

Sampling Mode

This oscilloscope only supports the real-time sampling mode. In this mode, the oscilloscope produces the waveform display from samples collected during one trigger event. The highest real-time sample rate on the analog channel of DS8000-R series is 10 GSa/s (note that for DS8034-R, it is 5 GSa/s). The current sample rate is displayed under CH SampleRate.

Sample Rate

Sampling is the process of converting the analog signal into the digital signal at a specified time interval and then restoring them in sequence. The sample rate is the reciprocal of the time interval.
The sample rate of the analog channel is related to the current channel mode. The maximum real-time sample rate in the single-channel mode of the oscilloscope is 10 GSa/s. The maximum real-time sample rate in the dual-channel mode is 5 GSa/s, and the maximum real-time sample rate in the 4-channel mode is 2.5 GSa/s.
Note: For DS8034-R, the maximum real-time sample rate in the single-channel
mode of the oscilloscope is 5 GSa/s. The maximum real-time sample rate in the dual-channel mode is 5 GSa/s, and the maximum real-time sample rate in the 4-channel mode is 2.5 GSa/s
Tip
When you click the label at the top of the screen to stop sampling, the oscilloscope will maintain its last captured graph. At this time, you can still expand or zoom the waveforms horizontally or vertically.
RIGOL Chapter 4 To Set the Sample System
4-8 DS8000-R User Guide
Note: The sample rate is displayed both in the label at the
upper part of the screen and in the CH SampleRate menu. To indirectly
modify the sample rate, click the label at the upper part of the screen. Then adjust the horizontal time base or modify the memory depth to modify the sample rate. In addition, if the triggering source selects the analog channel, it will cause the channel mode to change, affecting the sampling rate.
The impact of low sample rate on the waveform:
1. Waveform Distortion: when the sample rate is too low, some waveform
details are lost, and the sample waveform displayed is rather different from the actual waveform of the signal.
2. Waveform Aliasing: when the sample rate is twice lower than the actual
signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt from the sample data is smaller than the actual signal frequency.
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.
Tip
Single-channel mode: only one of the four channels (CH1/CH2/CH3/CH4) is enabled. Dual-channel mode: either CH1 or CH2 is enabled; and either CH3 or CH4 is enabled. 4-channel mode: CH1/CH2 are both enabled or CH3/CH4 are both enabled.

Note: In "Auto" mode, the oscilloscope selects the memory depth automatically
according to the current sample rate.

Anti-Aliasing

At a slower sweep speed, the sample rate is reduced, and a dedicated display algorithm can be used to minimize the possibility of aliasing.
In the Acquisition menu, click Anti-aliasing to enable or disable the anti-aliasing function. By default, anti-aliasing is disabled. In this case, it is more likely to generate waveform aliasing.
Note: This function should be enabled when the horizontal time base has a large
deviation from the period of the signal under test (e.g. when the horizontal time base is greater than five-fold the period of the signal under test). It is available when the timebase mode is "YT".

Horizontal Expansion

Horizontal expansion indicates the reference position that the screen waveform is referenced to when it is horizontally expanded or compressed. In YT mode, in the Acquisition menu, click More Expand and then select the desired reference position. The horizontal expansion reference supported by the oscilloscope includes Center, Left, Right, Trigger, and User. The default is "Center".
Center: when the horizontal time base is modified, the waveform will be
expanded or compressed horizontally relative to the screen center.
Left: when the horizontal time base is modified, the waveform will be expanded
or compressed horizontally relative to the leftmost position of the screen.
Right: when the horizontal time base is modified, the waveform will be
expanded or compressed horizontally relative to the rightmost position of the screen.
Trigger: when the horizontal time base is modified, the waveform will be

Chapter 5 To Trigger the Oscilloscope

As 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 the digital oscilloscope, it samples waveform continuously no matter whether it is stably triggered, but only stable trigger can be stably displayed. The trigger module ensures that every time base sweep or acquisition starts from the user-defined trigger condition, namely every sweep is synchronous with the acquisition and the waveforms acquired is overlapped so as to display the stable waveforms.
Trigger settings should be based on the features of the input signal. To quickly capture the desired waveform, you need to understand the signal under test. This oscilloscope provides abundant trigger types that help you focus on the desired waveform details.

Trigger Source

Click on the function navigation icon at the lower-left corner of the screen to open the function navigation. Click on the trigger icon to open the trigger setting
menu. Click Source to select the desired source.
Analog channels (CH1-CH4), EXT (external trigger), or AC Line can all be selected as the trigger source.
Analog channel input:
Signals input from analog channels CH1-CH4 can all be used as trigger sources. No matter whether the channel selected is enabled, the channel can work normally.
External trigger input:
The external trigger source can be used to trigger on the fifth channel while all the other four channels are acquiring data. The trigger signal (e.g. external clock or signal of the circuit under test) will be connected to EXT trigger source via the external trigger input terminal [EXT TRIG] connector. You can set the trigger conditions within the range of the trigger level (from -5 V to +5 V).
AC line input:
The trigger signal is obtained from the AC power input of the oscilloscope. AC trigger is usually used to measure signals relevant to the AC power frequency. For example, stably triggering the waveform output from the transformer of a transformer substation. It is mainly used in related measurements of the power industry.
Chapter 5 To Trigger the Oscilloscope RIGOL

Trigger Level

The adjustment of the trigger level is related to the type of the trigger source.
When the trigger source is selected from CH1 to CH4, click on the trigger setting
label at the right-upper corner of the screen. Then, in the "Trigger Setting" window, input the trigger level with the pop-up numeric keypad into the "Level" field. You can also click the Up and Down arrow at the right of the "Level" field to increase or decrease the trigger level. During the adjustment, a trigger level line (the color of the trigger level line should be consistent with that of the channel color) and a trigger label " " are displayed on the screen, and they move up and down with the variation of the trigger level. When you stopping modifying the trigger level, the trigger level line disappears in about 2 s. The current trigger level value is displayed at the upper-right corner of the screen.
Note: In Runt Trigger, Slope Trigger, and Window trigger, you need to set the
upper and lower limits of the trigger level. In the trigger menu, you can set the specified trigger level. The difference between the current upper limit and lower limit of the trigger level is displayed at the upper-right side of the screen. Two trigger level labels ( and ) are displayed at the left side of the screen. Meanwhile, the real-time trigger level information is displayed at the lower-left side of the screen, as shown in the figure below. H indicates the upper limit of
the trigger level, L indicates the lower limit of the trigger level, and indicates the deviation of the trigger level.
When the trigger source is EXT, you can also set the trigger level in the "Trigger"
menu. The current trigger level value is displayed at the upper-right corner of the screen.
Note: For this trigger source, only the variation of the trigger level value is
displayed on the screen during the adjustment of the trigger level, without displaying the trigger level lines on the screen.
When the trigger source is AC Line, there is no trigger level.

Trigger Mode

The following is the schematic diagram of the acquisition memory. To easily understand the trigger event, we classify the acquisition memory into the pre-trigger buffer and post-trigger buffer.
Figure 5-1 Schematic Diagram of the Acquisition Memory
After the system runs, the oscilloscope operates by first filling the pre-trigger buffer. It starts searching for a trigger after the pre-trigger buffer is filled. While searching for the trigger, the data sampled will still be transmitted to the pre-trigger buffer (the new data will continuously overwrite the previous data). When a trigger is found, the pre-trigger buffer contains the data acquired just before the trigger. Then, the oscilloscope will fill the post-trigger buffer and display the data in the acquisition memory.
DS8000-R provides three trigger modes: Auto, Normal, and Single. The default is Auto. The trigger mode is displayed at the upper-right corner of the screen: A (Auto), N (Normal), and S (Single).
Auto: In this trigger mode, if the specified trigger conditions are not found,
triggers are forced and acquisitions are made so as to display the waveforms. This trigger mode should be used when the signal level is unknown or the DC should be displayed as well as when forcible trigger is not necessary as the trigger condition always occurs.
Normal: In this trigger mode, triggers and acquisitions only occur when the
specified trigger conditions are found. This trigger mode should be used when the signal is with low repetition rate or only the event specified by the trigger setting needs to be sampled as well as when auto trigger should be prevented to acquire stable display.
Single: In this trigger mode, the oscilloscope performs a single trigger and
acquisition when the specified trigger conditions are found, and then stops. This trigger mode should be used when you need to perform a single acquisition of the specified event and analyze the acquisition result (you can pan and zoom the currently displayed waveform, and the subsequent waveform data will not overwrite the current waveform). After a single trigger mode is initiated, the operating status of the oscilloscope is in "STOP" state.

Click on the trigger setting label at the upper-right corner of the screen. Then the following window is displayed. Click to select "Auto", "Normal", or "Single" as the trigger mode.
Note: In "Normal" and "Single" trigger modes, press Force on the front panel to
generate a trigger signal forcibly.

Trigger Coupling

Trigger coupling decides which kind of components will be transmitted to the trigger module. Please distinguish it from "Channel Coupling".
Note: Trigger coupling is only valid when the trigger type is Edge and the trigger
source is an analog channel.
In the "Trigger" menu, click Coupling to select the desired coupling mode. DS8000-R provides four coupling mode: DC, AC, LFR, and HFR. By default, it is DC.
DC: allows DC and AC components to pass the trigger path. AC: blocks the DC components and attenuates signals. LFR: blocks the DC components and rejects the low-frequency components. HFR: rejects the high frequency components.

Trigger Holdoff

Trigger holdoff can be used to stably trigger on complex repetitive waveforms that have multiple edges (or other events) between waveform repetitions (such as pulse series). Holdoff time indicates the time that the oscilloscope waits for re-arming the trigger module after generating a correct trigger. The oscilloscope will not trigger even if the trigger condition is met during the holdoff time and will only re-arm the trigger module after the holdoff time expires.
Tip
When "AC" or "LFR" is selected under Coupling, no trigger level lines and trigger icons are displayed. When you adjust the trigger level, you can only see the changes of the trigger level values at the upper-right corner of the screen.
RIGOL Chapter 5 To Trigger the Oscilloscope
5-6 DS8000-R User Guide
For example, to stably trigger the repetitive pulse series as shown in the figure below, the holdoff time should be set to a value that is greater than t1 and smaller than t2.
Figure 5-2 Schematic Diagram of Trigger Holdoff
In the "Trigger" menu, click Holdoff (for some trigger, Holdoff is a sub menu under More, at this time, click More Holdoff) and then set the holdoff time with the pop-up numeric keypad or scroll with the mouse to adjust the holdoff time. The adjustable range of holdoff time is from 8 ns to 10 s. By default, it is 8 ns.

Noise Rejection

Noise rejection can reject the high frequency noise in the signal and reduce the possibility of miss-trigger of the oscilloscope.
In the "Trigger" menu, click Noise Reject continuously (for some trigger, Noise Reject is a sub menu under More, at this time, click More Noise Reject) to enable or disable noise rejection.
Note: This function is only available when the trigger source is an analog channel.

Tip
For a better observation of the waveform details in the video signal, you can
set a larger memory depth first.
In the trigger debugging process of video signals, the frequency in different
part of the signal can be reflected by a different brightness, as RIGOL digital oscilloscope provides the intensity graded color display function. Experienced users can quickly judge the signal quality and discover abnormalities during the debugging process.

Pattern Trigger

Identifies a trigger condition by searching for a specified pattern. This pattern is a logical "AND" combination of channels. Each channel can be set to H (high), L (low), or X (don't care). A rising or falling edge (you can only specify a single edge) can be specified for one channel included in the pattern. When an edge is specified, the oscilloscope will trigger at the edge specified if the pattern set for the other channels is true (namely the actual pattern of the channel is the same as the preset pattern). If no edge is specified, the oscilloscope will trigger on the last edge that makes the pattern true. If all the channels in the pattern are set to "X", the oscilloscope will not trigger.

H: sets the pattern of the channel selected to "1", i.g. the voltage level is higher
than the trigger level of the channel.
L: sets the pattern of the channel selected to "0", i.g. the voltage level is lower
than the trigger level of the channel.
X: sets the pattern of the channel selected to "X", i.g. this channel is not used as
a part of the pattern. When all channels in the pattern are set to "X", the oscilloscope will not trigger.
Rising: sets the pattern to the rising edge ( ) of the channel selected.
