RIGOL Chapter 2 To Set the Vertical System 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.
RIGOL Chapter 2 To Set the Vertical System 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 can 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.
RIGOL Chapter 2 To Set the Vertical System Probe Ratio You can set the probe attenuation ratio manually. The probe ratio values available are as shown in the table below. Table 2-1 Probe Attenuation Coefficient Attenuation Coefficient (Amplitude of Signal Under Test: Menu Amplitude of Displayed Waveform) 0.01X 1:100 0.02X 1:50 0.05X 1:20 0.1X 1:10 0.2X 1:5 0.
Chapter 2 To Set the Vertical System RIGOL Input Impedance This oscilloscope provides two input impedance modes (1 MΩ (default) and 50 Ω) to reduce the circuit load caused by the interaction of the oscilloscope and the circuit to be tested. 1MΩ: the input impedance of the oscilloscope is rather high and the current flowing into the oscilloscope from the circuit under test can be ignored. 50Ω: match the oscilloscope with a device with 50 Ω output impedance.
RIGOL Chapter 2 To Set the Vertical System 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.

Chapter 3 To Set the Horizontal System RIGOL Chapter 3 To Set the Horizontal System The contents of this chapter: Delayed Sweep Time Base Mode Horizontal Scale Horizontal Reference MSO2000A/DS2000A User’s Guide 3-1
RIGOL Chapter 3 To Set the Horizontal System Delayed Sweep Delayed sweep can be used to enlarge a length of waveform horizontally to view the waveform details. Press MENU in the horizontal control area (HORIZONTAL) at the front panel and press Delayed to enable or disable delayed sweep. In delayed sweep mode, the screen is divided into two display areas as shown in the figure below. Note: To enable delayed sweep, the current time base mode must be “Y-T” and the “Pass/Fail test” must be disabled.
Chapter 3 To Set the Horizontal System RIGOL The Waveform after Enlargement: The waveform in the lower part of the screen is the horizontally expanded waveform. Compared to the main time base, the delayed time base has increased the waveform resolution (as shown in the figure above). Note: The delayed time base should be less than or equal to the main time base and can be modified by rotating HORIZONTAL SCALE. Tip You can also press down HORIZONTAL to directly switch to delayed sweep mode.
RIGOL Chapter 3 To Set the Horizontal System Time Base Mode Press MENU in the horizontal control area (HORIZONTAL) at the front panel and then press Time Base to select the time base mode of the oscilloscope and the default is Y-T. Y-T 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 greater than or equal to 200 ms, the instrument enters slow sweep mode.
Chapter 3 To Set the Horizontal System RIGOL 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 quadrant I and IV, namely within (0 to π/2) or (3π/2 to 2π).
RIGOL 4. Chapter 3 To Set the Horizontal System 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.
Chapter 3 To Set the Horizontal System RIGOL Roll Mode In this mode, the waveform scrolls from the right to the left to update the display. The range of horizontal scale adjustment is from 200.0 ms to 1.000 ks. Note: When Roll mode is enabled, the waveform “horizontal position”, “Delayed Sweep”, “Protocol Decoding”, “Pass/Fail Test”, “Measurement Range”, “Waveform Record”, “To Set the Persistence Time” and “To Trigger the Oscilloscope” are not available.
RIGOL Chapter 3 To Set the Horizontal System Horizontal Scale Horizontal scale, namely horizontal time base, refers to the time per grid in the horizontal direction on the screen and is usually expressed as s/div. Being similar to “Vertical Scale”, the horizontal scale can be adjusted in “Coarse” or “Fine” mode. Press MENU ScaleAdjust in the horizontal control area (HORIZONTAL) at the front panel to select the desired mode.
Chapter 3 To Set the Horizontal System RIGOL Horizontal Reference Horizontal reference is the reference position according to which the screen waveform is expanded or compressed horizontally when adjusting HORIZONTAL SCALE. In Y-T mode and the delayed sweep is disabled, press MENU HorRef in the horizontal control area (HORIZONTAL) at the front panel to select the desired reference mode and the default is “Center”.

RIGOL Chapter 4 To Set the Sample System Peak Detect 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 of the signal that might be lost. In this mode, signal confusion can be prevented, but the noise displayed would be larger.
Chapter 4 To Set the Sample System RIGOL Sample Mode This oscilloscope only supports real-time sample. In this mode, the oscilloscope samples and displays waveform within a trigger event. The maximum real-time sample rate of the analog channels of MSO2000A/DS2000A is 2 GSa/s and the current sample rate is displayed under the Sa Rate menu. Tip Press RUN/STOP to stop the sample, the oscilloscope will hold the last display.
RIGOL Chapter 4 To Set the Sample System Sample Rate Sample refers to the process that the oscilloscope converts analog signals to digital signals at certain time interval and stores the signals in sequence. The sample rate is the reciprocal of the time interval. The maximum real-time sample rate of the analog channels of MSO2000A/DS2000A is 2 GSa/s.
RIGOL Chapter 4 To Set the Sample System from the sample data does not reflect all the actual signal information. Pulse disappeared LA Sample Rate LA sampling refers to the process that the oscilloscope samples the compared digital signal at a certain time interval. LA sample rate is the reciprocal of the time interval. For example, the oscilloscope with 500 MSa/s LA sample rate samples digital signals once every 2 ns. The maximum sample rate of the digital channels of the oscilloscope is 1 GSa/s.
RIGOL Chapter 4 To Set the Sample System 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. MSO2000A/DS2000A provides 14 Mpts standard memory depth and up to 56 Mpts memory depth (option).
Chapter 4 To Set the Sample System RIGOL In “Auto” mode, the oscilloscope selects the memory depth automatically according to the current sample rate. At this point, you can adjust the memory depth indirectly by rotating HORIZONTAL SCALE to adjust the sample rate. LA Memory Depth Press Acquire, you can view the current memory depth of the digital channel in LA Mem Depth. The LA Memory Depth will change with the memory depth of the analog channel and can not be set separately.
Chapter 5 To Trigger the Oscilloscope RIGOL 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 waveform continuously no matter whether it is stably triggered, but only stable trigger can ensures stable display.
RIGOL Chapter 5 To Trigger the Oscilloscope Trigger Source Press MENU Source in the trigger control area (TRIGGER) at the front panel to select the desired trigger source. Signals input from CH1/CH2, the [EXT TRIG] connector or [LOGIC D0-D15] connector as well as the AC Line can all be used as trigger source. 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.
RIGOL Chapter 5 To Trigger the Oscilloscope Trigger Mode Trigger mode affects the way in which the oscilloscope searches for the trigger. 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. Note: The acquisition memory of the oscilloscope is a cyclic buffer and the new data would overwrite the old data until the acquisition finishes.
RIGOL Chapter 5 To Trigger the Oscilloscope waveform is displayed. Otherwise, “AUTO” is displayed and unstable waveform is displayed. Note: When the horizontal time base setting is 50 ms/div or greater, you can also observe the input waveform without a trigger signal in this mode. Normal: After this mode is selected, the oscilloscope enters the wait-for-trigger state and starts searching for trigger signals that meet the specified condition.
Chapter 5 To Trigger the Oscilloscope RIGOL 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).
RIGOL Chapter 5 To Trigger the Oscilloscope Trigger Holdoff Trigger holdoff 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 condition is met during the holdoff time and will only re-arm the trigger module after the holdoff time expires.
