To Enable the Analog Channel

MSO2000A/DS2000A provides 2 analog input channels (CH1 and CH2) and provides independent vertical control system for each channel. As the setting methods of the vertical systems of the two 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 input connector of CH1 and then press CH1 in the vertical control area (VERTIC A L) at the fro nt panel to enable CH1.

At this point, the channel setting men u is displaye d at the right s ide of the sc reen and the channel status l abel at the bott om of t he s creen (as sh own in the figure bel ow) 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 and trigger mode according to the input signal to make the waveform display easy t o be observed and measured.

Channel Coupling

The undesired signals can be filtered out by set ting the coupling mo de. For example, the signal under test is a square waveform with DC offset.  When the coupling mode is “DC”: the DC and AC components can 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 screen as shown in the figures below. You can also press Coupling continuously to switch the coupling mode.

Vertical Scale

Vertical scale refers to the voltage value per grid in the vertical direction on the screen and is usually expressed as V/div.

Press CH1  Volts/Div to select the desired adjustment mode of the vertical scale, or press VERTICAL SCALE to switch the adjustment mode quickly.  Coarse adjustment: set the vertical scale in 1-2-5 step nam ely 500 μV/div, 1

mV/div, 2 mV/div, 5 mV/div, 10 mV/div…10 V/div (take counterclockwise as an example).

 Fine adjustment: 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.

After the adjustment mode is selected, rotate VERTICAL vertical scale (clockwise to reduce the scale and counterclockwise to increase). The scale information in the channel status label (as shown in the figure below ) at the bottom of the screen will change accordingly during the adjustment. The adjus t able range of the vertical scale is related to the probe rati o and input im pedance currently set. By default, the probe ratio is 1X, the input impedance is 1 MΩ and the adjustable range of the vertical scale is from 500 μV/div to 10 V/div.

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 II I, na mely within (π/2 to π) or (π to 3π/2).

X-Y function can be used to measure the phase deviation occurred when the signal under test passes through a ci rcuit network. Connect the oscilloscope to the ci rcuit 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 enable X -Y mode. Rotate Horizontal

sample rate properly to get better Lissajous figure for better observation and measurement.

3. Rotate VERTICAL POSITION of CH1 and CH 2 t o display the signals at t he center of the screen and rotate VERTICAL

SCALE of CH1 and CH2 to make the signals easy to observe. At this point, the circle as shown in the figure below should be displayed.

MSO2000A/DS2000A User’s Guide 3-5

RIGOL Chapter 3 To Set the Horizontal System

4. Observe the measurement result shown in the figure above. According to the measurement schematic diagram of the phase deviation (as shown in Figure 3-2

), A/B (C/D) = 1. Thus, the phase deviation angle θ=±arcsin1=90°.

Note:

 The maximum sample rate of X-Y mode is 1.0 GSa/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 reduce the wavef o rm 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 X-Y mode is enabled , “Delayed Sweep” will be disabled automatically.  The following functions are not available in X-Y mode:

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 displays wav eform continuousl y no matter whether it is stably triggered, but only stable trigger can ensures stable display. The trigger module ensures that every time base sweep or acquisition starts from the input signal and the user-defined trigger condition, na mel y eve ry s wee p is s yn chronous to the acquisition and the waveforms acquired overlap to display stable waveform.

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. This oscilloscope provides abundant advanced trigger types which can help you to focus on t he desired waveform details.

Analog channel input:

Signals input from analog channels CH1 and CH2 can all be used as the trigger source. No matter whether the channel selected is enabled, the channel can work normally.

Digital ch an n e l in p ut:

Signal input from any digital channel of D0-D15 can all be used as the trigger sou rce. No matter whether the channel selected is enabled, the channel can work normally.

External trigger input:

Signals (such as external clock and signal of the circuit to be tested) input from the [EXT TRIG] connector can be us ed as the t ri g ger source. When this type of trigger source is selected, you can set the trigger level within -4 V to +4 V by rotating

TRIGGER

External trigger source can be used to connect external trigger signal to the [EXT TRIG] channel when both of the two channels are sampling data.

AC line:

The trigger signal is obtained f rom the AC power input o f the oscilloscope. AC trig ger is usually used to measure signals relev ant t o the AC power fre quency. For example, stably trigge r the wa vefor m output from the transf ormer of a tr ansforme r substat ion; it is mainly used in related measurements of the power industry.

Pre-trigger/Delayed trigger:

Acquire data before/after the trigger event. The trigger position is usually at the horizontal center of the screen. In full-screen display, seven-grid pre-trigger and delayed trigger information are displayed respectively. You can adjust the horizontal position of the waveform through HORIZONTAL pre-trigger information or delayed trigger information, through which the signal information before/after the trigger (such as captu r e the glitch generated by the circuit and analyze the pre-trigger data to find out the reasons for glitch) can be obtained.

Trigger Coupling

Trigger coupling decides which kind of components will be transmitted to the trigger module. Please distinguish it with “Channel Coupling”.

 DC: allow DC and AC components into the trigger path.  AC: block all the DC components and attenuate signals lower than 75 Hz.  LF Reject: block the DC components and reject the low frequency components

(lower than 75 kHz).

 HF Reject: reject the high frequency components (higher than 75 kHz).

Press MENU  Setting  Coupling in the trigger control area (TRIGGER) at the front panel to select the desired coupling type (the default is DC).

Trigger Holdoff

Trigger hol d o ff can be used to stably trigger the complex waveforms. Holdoff time is the amount of time that the oscilloscope waits before re-arming the trigger module. The oscilloscope will not trigger even if the trigger c ondition is met during the holdoff time and will only re-arm the trigger module after the holdoff time expires.

To capture the periodi c sig nal as sh own in the f ollowing figure (b), you nee d t o set a proper holdoff time to make each trigger is on the same position. Otherwise, the signal captured by the oscilloscope might be as shown in the figure (a).
