RIGOL Chapter 2 To Set the Vertical System
To Enable the Analog Channel
MSO1000Z/DS1000Z provides 4 analog input channels (CH1-CH4). As the setting
methods of the vertical systems of the four channels are the same, this chapter takes
CH1 as an example to illustrate the setting method of the vertical system.
Connect a signal to the ch annel connect or of CH 1 and the n p ress CH1 in the vertical
control area (VERTICAL) at the front panel to enable CH1. At this point, the channel
setting menu is displaye d at the ri ght si de of the scr een and the channel status label
at the bottom of the screen (as shown in the figure below) is highlighted. The
information displayed in the channel status label is related to the current channel
setting.
After the channel is turned on, modify the parameters such as the vertical scale,
horizontal time base, trigge r mode and trigger level according to the in put signal for
easy observation and measurement of th e wav eform.
Channel Coupling
The undesire d 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 mo de 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 blo cked.
When the coupling mode is "GND": the DC and AC components of the signal
under test are both blocked.
Press CH1 Coupling and use to select the desired coupling mode (the
default is DC). The current coupling mode is displayed in the channel status label at
the bottom of the s creen a s shown in t he figure below . You can also press Coupling
continuously to switch the coupling mode.

Bandwidth Limit
MSO1000Z/DS1000Z supports the bandwidth limit function which can reduce the
display noise. 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 limiting the bandwidth to 20 MHz, the high frequency components of the
signal under test that exceed 20 MHz are attenuated.
Press CH1, then press BW Limit continuously to switch the bandwidth limit state
(the default 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.
Note: Bandwidth limit can reduce the noise as well as attenuate or eliminate the
high frequency components of the signal.

Delay Calibration of the Analog Channel
When using an oscilloscope for actual measurement, the transmission delay of the
probe cable may bring relatively greater error (zero o ffset). MSO1000Z/DS1000Z
supports user to set a delay time to calibrate the zero offset of the corresponding
channel. Zero offset is defined as the offset of the crossing point of the waveform
and trigger level line relative to the trigger position, as shown in the figure below.
Figure 2-1 Zero Offset
Press CH1 Delay-Cal and use to set the desired delay time. The range
available is from -100 ns to 100 ns. Pressing down the multifunction knob will
reset the delay time to 0.00 s.
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. Take MSO1104Z-S as an example. The step values under different horizontal

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)
If the principal axis of the ellipse is within quadrant I and III, the phase deviation
angle obtained should be within quadr ant I an d 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 s hould be wit hin qua dr ant II an d III, namel y 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: measure the phase deviation of the input signals of two
channels.
Method 1: Use Lissajous method
1. Connect a sine signal to CH1 and then connect a sine signal with the same
frequency and amplitude but a 90° phase deviation to CH2.
2. Press AUTO and then adjust the vertical positions of CH1 and CH2 to 0 V.
3. Set the time base mode to XY, press X-Y and select "CH1-CH2". Rotate
Horizontal
SCALE to adjust the sample rate properly to get better
Lissajous figure for bet t e r obs e rvation and meas urement.
4. Rotate VERTICAL SCALE of CH1 and C H 2 to make the signals eas y to
observe. At this point, the circle as shown in the figure below should be
displayed.
5. Observe the measurement result shown in the figure above. According to the
measurement schematic diagram of the phase deviation (as shown in Figure
), A/B (C/D) = 1. Thus, the phase deviation angle θ=±arcsin1=90°.

Slow Sweep
Note:
The maximum sample rate of XY mode is 500 MSa/s. Generally, longer sample
waveform can ensure better display effect of Lissajous figure. But due to the
limitation of the memory depth, you have to r educe th e waveform sample rate
to acquire longer waveform (refer to the introduction in "Memory Depth").
Therefore, during the measurement, reducing the sample rate properly can
acquire better display effect of Lissajous figure.
When XY mode is enabled, "Delayed Sweep" will be disabled automatically.
Press X-Y to select "CH1-CH2, CH1-CH3, CH1-CH4, CH2-CH3, CH2-CH4,
CH3-CH4". After you choose a ny o f t h e opt i ons, the instrument automatically
turns on the two corresponding channels and turns off the other two channels.
The X-axis tracks the vo ltage of the first channel in each option; the Y-axis
tracks the voltage of the second channel in each option.
The following functions are not available in XY mode:
"Delayed Sweep", "Vectors", "Proto c ol Decoding", "Acquisition Mode",
"Pass/Fail Test", "W aveform Record" "Digital Channel" and "To Set the

".
Roll Mode
In this mode, the waveform scrolls from right to left to update the display.
The horizontal position and trigger control of the waveform are not available. The
range of horizontal scale adjustment is from 200 ms to 50.0 s.
Note: When R oll mode is enabled, the w av eform "horizontal position", "Delayed
Sweep", "Protocol Decoding", "Pass/Fail Test", "Waveform Record", "To
Set the Persistence Time" and "To Trigger the Oscilloscope" are not available.
Slow sweep is similar to Roll mode. In YT mode, when the horizontal time base is
set to 200 ms/div or slower, the instrument enters "slow sweep" mode in which the
instrument first acquires the data at the left of the trigger point an d 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 slow sweep mode is used to
observe low frequency signal, DC "Channel Coupling" mode is recommended.

The acquisition mode is used to control how to generate waveform points from
sample points.
Press Acquire Mode at the front panel and use to select the desired
acquisition mode (the default is normal), then press down the knob to select this
mode. You can also press Mode continuously to switch the acquisition mode.
Normal
In this mode, the oscilloscope sam ples the signal at equal time int erval to rebuild th e
waveform. For most of the waveforms, the best display effect can be obtained using
this mode.
Peak Detect
In this mode, the oscilloscope acquires the maximum and minimum values of the
signal within the sample in terval to get the envel ope of the signal or the narrow pulse
of the signal that might be lost. In this mode, signal confusion can be p rev e nted but
the noise displayed would be larger.
In this mode, the oscilloscope can display all t he pulses with pulse widths at least as
wide as the sample period.
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 "Average" mode is selected, press Averages and us e to set the desired
number of averages. The number of averages can be set to 2, 4, 8, 16, 32, 64, 128,

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 neighbouring part and displays them on the
screen. For digital oscilloscope, it samples wa veform continuously n o matter wh ether
it is stably triggered, but only stable trigger can ensure stable display. The trigger
module ensures that every time base sweep or acquisition starts from the
user-defined trigger condition, namely every sweep is synchronous to the acquisition
and the waveforms acq u ired overlap to display st a ble waveform.
Trigger setting should be based on t he features of the input signal, thus you n eed to
