To Enable or Disable the Analog Channel
Enable the analog channel:
Connect a signal to the channel connector of CH1, and then press 1 in the vertical
control area (Vertical) on the front panel to enable CH1. Then, the backlight of the
channel is illuminated. 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. You can also enable the touch
screen to tap the channel status label to enable the channel.
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, press 1 on the front panel in the vertical control area
(Vertical) or enable the touch screen to tap the waveform activation channel
displayed on 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, press the channel key 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 press the channel key to disable
the channel. You can also enable the touch screen to tap 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

status label to disable CH1. If CH1 is disabled, the channel status label is shown in
the following figure.
Chapter 2 To Set the Vertical System RIGOL
MSO5000 User Guide 2-3
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
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. The adjustable range of the vertical scale is from 500 μV/div to 10 V/div.
When CH1 is turned on, you can adjust the vertical scale with the following three
methods:
⚫ Rotate Vertical SCALE that corresponds to CH1 to adjust the vertical scale
(clockwise to reduce the scale and counterclockwise to increase).
⚫ Enable the touch screen function and adjust the vertical scale with the pinch &
stretch gesture on the touch screen. For details, refer to the "Pinch & Stretch"
section.
⚫ Enable the touch screen function, and tap the channel status label at the bottom
of the screen. The following window is displayed. Tap the icon at the
right side of the Scale input field to decrease or increase the scale. You can also
tap the Scale input field to input a specific value with the displayed numeric
keypad.
In the vertical control area (Vertical) on the front panel, press Vertical SCALE
to adjust the vertical scale in "Coarse" (by default) or "Fine" mode. You can also
press 1 → More → Fine to enable or disable fine adjustment.
⚫ Fine adjustment: Rotate Vertical SCALE to further adjust the vertical scale
within a relatively smaller range to improve vertical resolution. 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.
⚫ Coarse adjustment (take counterclockwise as an example): Rotate Vertical
SCALE to set the vertical scale at 1-2-5 step, i.e. 500 μV/div, 1 mV/div, 2 mV/div,
5 mV/div, 10 mV/div…10 V/div.

Vertical Expansion
When changing the vertical scale of the analog channel by rotating the Vertical
SCALE knob, you can select to expand or compress the waveform around the
"Center" or "GND" (Ground). By default, "GND" is selected under Expand.
Press 1 → More, then press 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 four
methods:
⚫ Rotate Vertical OFFSET that corresponds to CH1 to adjust the vertical
offset within the adjustable range. Rotate this knob clockwise to increase the
vertical offset, and rotate it counterclockwise to reduce the vertical offset.
Pressing down the knob can quickly reset the vertical offset (set the vertical
offset to 0).
⚫ Menu setting: Press 1 → More → Offset, and then the numeric keypad is
displayed. Input the offset value with the numeric keypad.
⚫ Enable the touch screen, and then adjust the vertical offset with the drag
gesture. For details, refer to the "Drag" section.
⚫ Enable the touch screen function, and tap the channel status label at the bottom
of the screen. The following window is displayed. Tap the icon at the
right side of the Offset input field to decrease or increase the offset. You can
also tap 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.
Press 1 to open the setting menu of CH1. Then, press Coupling continuously or
rotate the multifunction knob to select the desired coupling mode (by default, it
is DC). The current coupling mode is displayed in the channel status label at the
bottom of the screen, as shown in the figure below. You can also enable the touch
screen, and then touch the CH1 setting menu to select the desired coupling mode.
DC AC GND
Bandwidth Limit
MSO5000 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, 100 MHz, or 200
MHz, the high frequency components found in the signal under test that are
greater than 20 MHz, 100 MHz, or 200 MHz are attenuated.
Press 1 to open the setting menu of CH1.Then, press BW Limit continuously or
rotate the multifunction knob to select the desired bandwidth limit. Press down
the knob to select it. By default, it is OFF. When the bandwidth limit is enabled, the
character "B" will be displayed in the channel status label at the bottom of the screen,

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. MSO5000 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.
Press 1 → More → Offset Cal, rotate the multifunction knob or use the pop-up
numeric keypad to set the offset calibration value.
Note: If the zero-cross voltage of the channel has a larger amplitude offset that
exceeds the adjustable null range, please perform self-calibration for the
instrument to ensure the measurement accuracy. For details, refer to
descriptions in "Self-calibration".

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 related to the model type.
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 three methods:
⚫ Rotate Horizontal SCALE to adjust the horizontal time base within the
available range (clockwise to reduce the horizontal time base and
counterclockwise to increase).
⚫ Enable the touch screen function and adjust the horizontal time base with the
pinch & stretch gesture on the touch screen. For details, refer to the "Pinch &
Stretch" section.
⚫ Enable the touch screen function, and tap the horizontal time base label
at the top of the screen. The following window is displayed. Tap the
icon at the right side of the Scale input field to decrease or increase
the horizontal scale. You can also tap the Scale input field to input a specific
value with the displayed numeric keypad.
In the Horizontal control area (Horizontal), rotate the Horizontal SCALE knob
to switch the adjustment mode between "Coarse" and "Fine" (by default, it is Coarse).
You can also press Acquire → Fine to enable or disable the fine adjustment of the
horizontal time base.
⚫ Coarse adjustment: Rotate the Horizontal SCALE knob will adjust the
horizontal time base of the waveforms of all channels at 1-2-5 step within the
adjustable range. Rotate it clockwise to reduce the horizontal time base, and
counterclockwise to increase the horizontal time base.
⚫ Fine adjustment: Rotate the Horizontal SCALE knob will adjust the
horizontal time base of the waveforms of all channels with a minor step value
within the adjustable range. Rotate it clockwise to reduce the horizontal time

base, and counterclockwise to increase the horizontal time base.
Note: When the delayed sweep is enabled, rotate the Horizontal SCALE knob
to adjust the time base for the delayed sweep. The delayed sweep time base
displayed in the center of the screen will be changed accordingly, as shown in
the following figure.
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
horizontal position is a positive (negative) value.
While you change the horizontal position, the waveform trigger points and the
displayed waveforms of all channels are moved left and right. The horizontal position
at the right-upper corner of the screen changes accordingly, as shown in the figure
below.
You can adjust the horizontal position with the following three methods:
⚫ Rotate Horizontal POSITION to adjust the horizontal position of the
waveforms of all channels. When you rotate it clockwise, the waveform trigger
point moves right on the screen; when you rotate it counterclockwise, the
waveform trigger point moves left on the screen. Pressing down the knob can
quickly reset the horizontal position (reset to 0).
⚫ Enable the touch screen function and adjust the horizontal position with the drag
gesture on the touch screen. For details, refer to the "Drag" section.
⚫ Enable the touch screen function, and tap the horizontal position label
at the top of the screen. The following window is displayed. Tap the
icon at the right side of the Pos input field to decrease or increase the horizontal
position. You can also tap the Pos input field to input a specific value with the
displayed numeric keypad.
Decrease the position Increase the position
RIGOL Chapter 3 To Set the Horizontal System

Note: When the delayed sweep is enabled, rotate the Horizontal POSITION
knob to adjust the horizontal position of the delayed sweep (press down the knob to
quickly reset it). The horizontal position of the delayed sweep at the upper-right
corner of the screen changes accordingly.
Delayed Sweep
Delayed sweep can be used to enlarge a length of waveform horizontally to view
waveform details.
In the horizontal control area on the front panel, press Zoom to enable or disable
the delayed sweep. By default, it is disabled. You can also press Acquire → More →
Zoom to enable or disable the delayed sweep function.
Note: To enable the delayed sweep, you must ensure that the current time base
mode is "YT".
In delayed sweep mode, the screen is divided into two display areas as shown in
Figure 3-1.

Waveform before enlargement:
The waveform in the area that is not covered by subtransparent blue in the upper
part of the screen is the waveform before enlargement. Its horizontal time base (also
called main time base) is displayed at the upper-left corner of the screen. You can
rotate the Horizontal POSITION knob to move the area left and right or rotate
the Horizontal SCALE knob to enlarge or reduce this area.
Note: If you need to modify the horizontal time base (also called main time base) of
the normal sweep, please disable the delayed sweep function first. Rotate the
Horizontal SCALE knob to set the required main time base, and then
enable the delayed sweep function.
Waveform after enlargement:
The waveform in the lower part of the screen is the horizontally expanded delayed
sweep waveform. Its horizontal time base (also called the time base of the delayed
sweep) is displayed on the screen. Compared with the main time base, the time
based of the delayed sweep has increased the waveform resolution, as shown in
Figure 3-1. At this time, you can rotate the Horizontal SCALE knob to adjust
the time base of the delayed sweep, and rotate the Horizontal POSITION
knob to adjust the horizontal position of the delayed sweep.
Note: The time base of the delayed sweep should be smaller than or equal to the
main time base.

Timebase Mode
MSO5000 series supports three available time base modes: YT mode, XY mode, and
ROLL mode. By default, the time base mode is YT.
Press Acquire → Timebase Mode on the front panel, and then rotate the
multifunction knob to select the desired time base mode. Then, press down the
knob to select the mode. You can also press Timebase Mode continuously to select
the mode or enable the touch screen to tap the desired mode and select it.
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 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
Chapter 4 To Set the Sample System RIGOL
MSO5000 User Guide 4-3
According to sin=A/B or C/D, is the phase deviation angle between the two
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 (π/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. Press AUTO, after you select "XY" mode, rotate the Horizontal SCALE to
adjust the sample rate properly to obtain a better view of Lissajous graph for
observation and measurement.
3. Rotate the Vertical SCALE knob that corresponds to CH1 and CH2
respectively 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
signals is =arcsin1=90°.
RIGOL Chapter 4 To Set the Sample System
4-4 MSO5000 User Guide
Note:
⚫ In XY mode, CH1 and CH2 are forced to be enabled; CH3 and CH4 are forced to
be disabled. The maximum sample rate in XY mode is 2 GSa/s. 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", "Waveform Recording & Playing", and
"Digital Channel".
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. Press More → Auto
ROLL to select "ON". The system automatically enters the ROLL mode, and there is
no slow sweep.
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".
Chapter 4 To Set the Sample System RIGOL
MSO5000 User Guide 4-5
Acquisition Mode
The acquisition mode is used to control how to generate waveform points from the
sample points.
MSO5000 supports the following four acquisition modes: Normal, Average, Peak, and
High Resolution. By default, the acquisition mode is Normal.
Press Acquire → Acquisition on the front panel, and then rotate the multifunction
knob to select the desired acquisition mode. Then, press down the knob to
select the mode. You can also press Acquisition continuously to select the mode or
enable the touch screen to tap the desired mode and select it.
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, press Averages and rotate the multifunction
knob or use the numeric keypad to set the desired number of averages. You can
also use the pop-up numeric keypad to input the average count. When the average
count value is not in power-of-2 increments, a prompt message "Truncation average
error" will be displayed. At this time, a value that is smaller than the one you input
and the closest to power-of-2 increments 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.
RIGOL Chapter 4 To Set the Sample System
4-6 MSO5000 User Guide
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.
Chapter 4 To Set the Sample System RIGOL
MSO5000 User Guide 4-7
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
much smoother waveform on the screen and improves the vertical resolution. 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 signal bandwidth does not exceed 1/32 of the sampling
rate.
⚫ 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 MSO5000
series is 8 GSa/s. The current sample rate is displayed under CH SampleRate, and
you can press More → CH SampleRate to view it.
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 8
GSa/s. The maximum real-time sample rate in the half-channel mode is 4 GSa/s, and
the maximum real-time sample rate in the all-channel mode is 2 GSa/s.
Tip
Press RUN/STOP on the front panel to stop sampling, and then the oscilloscope
will maintain its last captured graph. You can still expand or zoom the waveforms
by using the horizontal and vertical control knobs.
RIGOL Chapter 4 To Set the Sample System
4-8 MSO5000 User Guide
Note: The sample rate is displayed both in the status bar at the upper part of the
screen and in the CH SampleRate menu. To indirectly modify the sample
rate, rotate the Horizontal SCALE knob to adjust the horizontal time
base or modify the memory depth.
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.
Half-channel mode: either CH1 or CH2 is enabled; and either CH3 or CH4 is
enabled.
All-channel mode: CH1/CH2 are both enabled or CH3/CH4 are both enabled.
Note that the currently enabled channel should be used as the trigger source at
this time.
Chapter 4 To Set the Sample System RIGOL
MSO5000 User Guide 4-9
LA Sample Rate
LA sampling is the process of sampling on the compared digital signals at a certain
time interval. LA sample rate is the reciprocal of the time interval. For example, if the
LA sample rate is 500 MSa/s, it indicates that the oscilloscope will make data
acquisition on the digital signals at an interval of 2 ns. The maximum LA sample rate
of the oscilloscope is 1 GSa/s, and its display value is related to the sample rate of the
current analog channel.
Note:
⚫ The digital signals here mentioned refers to the signal obtained from the
comparison between the input signal and the user-defined threshold level. The
rule of the comparison is that when the amplitude of the input signal is greater
than the threshold level, it is judged to be the logic high level; when the
amplitude of the input signal is smaller than the threshold level, it is judged to
be the logic low level.
⚫ LA sample rate is displayed under the LA SampleRate menu. To indirectly
modify the LA sample rate, rotate the Horizontal SCALE knob to adjust
the horizontal time base or modify the memory depth.
Memory Depth
Memory depth refers to the number of points of the oscilloscope that can store in one
trigger acquisition. It reflects the storage capability of the acquisition storage. This
oscilloscope is equipped with memory depth of up to 200 Mpts (option).

the analog channel, and cannot be set separately. The maximum LA memory depth is
25 Mpts.
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.
Press Acquire → 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).
Horizontal Expansion
Horizontal expansion indicates the reference position that the screen waveform is
referenced to when it is horizontally expanded or compressed in adjusting the
Horizontal SCALE knob. In YT mode, press Acquire → More → Expand and
then rotate the multifunction knob to select the desired reference position. Press
down the knob to select it. You can also press Expand continuously to select it or
enable the touch screen to tap the desired reference. 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. You can
quickly reset to 0.
⚫ 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
expanded or compressed horizontally relative to the trigger point.
⚫ User: when the horizontal time base is modified, the waveform displayed will be
expanded or compressed horizontally relative to the user-defined reference
position.
After you select "User", press Expand User and then rotate the multifunction
knob to set the expansion reference. Its available range is from the
rightmost position of the screen to the leftmost position of the screen. By default,

Chapter 5 To Trigger the Oscilloscope RIGOL
MSO5000 User Guide 5-1
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.

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. If the acquisition is activated via RUN/STOP, the oscilloscope will repeat
this process; if the acquisition is activated via SINGLE, the oscilloscope will stop
after finishing a single acquisition (you can pan and zoom the currently displayed
waveform).
MSO5000 provides three trigger modes: Auto, Normal, and Single. The default is
Auto.
In the trigger control area (Trigger) on the front panel, press Mode to quickly switch
the current trigger mode. The trigger mode is displayed at the upper-right corner of
the screen: A (Auto), N (Normal), and S (Single).

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.
Note: In "Normal" and "Single" trigger modes, pressing Force can generate a
trigger signal forcibly.
In addition, you can enable the touch screen to set the trigger mode. Enable the
touch screen and tap the trigger setting label at the upper-right
corner of the screen. Then the following window is displayed. Tap to select "Auto",
"Normal", or "Single" as the trigger mode.
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.
Press Menu → Coupling in the trigger control area (Trigger) on the front panel.
Then, rotate the multifunction knob to select the desired coupling mode (by
default, it is DC). You can also press Coupling continuously to select it or enable the
touch screen to select the desired coupling mode with touch gestures.
⚫ DC: allows DC and AC components to pass the trigger path.
RIGOL Chapter 5 To Trigger the Oscilloscope
5-6 MSO5000 User Guide
⚫ 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.
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 control area (Trigger) on the front panel, press Menu → Holdoff (for
some triggers, Holdoff is a sub menu under More, at this time, press Menu →
More → Holdoff) and then rotate the multifunction knob at a small step to
modify the holdoff time (the holdoff to this time when the waveforms are stably
triggered; by default, the holdoff time is 8 ns). Also, you can use the numeric keypad
to set the holdoff time. The adjustable range of holdoff time is from 8 ns to 10 s.
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.

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 control area (Trigger) on the front panel, press Menu to enter the
trigger setting menu, then press Noise Reject continuously (for some triggers,
Noise Reject is a sub menu under More, at this time, press Menu → More →
Noise Reject) to enable or disable noise rejection.
