2 To Set the Vertical System RIGOL 2 To Set the Vertical System The contents of this chapter: To Enable the Channel Channel Coupling Bandwidth Limit Probe Ratio Input Impedance Waveform Invert Vertical Scale Vertical Expansion Amplitude Unit Channel Label Delay Calibration DS2000A User’s Guide 2-1
RIGOL 2 To Set the Vertical System To Enable the Channel DS2000A provides 2 analog input channels (CH1 and CH2) and provides independent vertical control system for each channel. As the vertical system setting methods of the 2 channels are completely the same, this chapter takes CH1 as an example to introduce the setting method of the vertical system.
2 To Set the Vertical System RIGOL 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.
RIGOL 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 Menu 0.01X 0.02X 0.05X 0.1X 0.2X 0.
RIGOL 2 To Set the Vertical System Waveform Invert When waveform invert is enabled, the waveform display rotates 180 degree relative to the ground potential. When waveform invert is disabled, the waveform display is normal. Press CH1 Invert to enable or disable waveform invert. Vertical Scale The vertical scale can be adjusted in “Coarse” or “Fine” mode. Press CH1 Volts/Div to select the desired mode.
RIGOL 2 To Set the Vertical System Vertical Expansion When using VERTICAL SCALE to change the vertical scale of the analog channel, you can choose to expand or compress the signal vertically around the center of the screen or the ground point of the signal. Press Utility System VerticalExp to select “Center” or “Ground” and the default is “Ground”. Center: when the vertical scale is modified, the waveform will expand or compress around the center of the screen.
RIGOL 2 To Set the Vertical System Channel Label You can modify the labels used to mark the analog channels (CH1 and CH2) at the left side of the screen. The label is the number of the channel (such as ) by default and the length of the label can not exceed 4 characters. Note: Only English input method can be used for this operation. Press CH1 Label to enter the label modification interface as shown in the figure below. Name Input Area For example, change “ Keyboard ” to “ Upper/Lower Case Switch ”.
RIGOL 2 To Set the Vertical System Delay Calibration When using an oscilloscope for actual measurement, the transmission delay of the probe cable may bring relatively greater error (zero offset). DS2000A allows users 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.
3 To Set the Horizontal System RIGOL 3 To Set the Horizontal System The contents of this chapter: Delayed Sweep Time Base Mode Horizontal Scale Horizontal Reference DS2000A User’s Guide 3-1
RIGOL 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. Note that to enable delayed sweep, the current time base mode must be “Y-T” and the “Pass/Fail test” must be disabled. In delayed sweep mode, the screen is divided into two display areas as shown in the figure below.
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. Note: Compared to the main time base, the delayed time base has increased the waveform resolution (as shown in the figure above). The delayed time base should be less than or equal to the main time base. Tip You can also press down HORIZONTAL to directly switch to delayed sweep mode.
RIGOL 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 This mode is the main time base mode and is applicable to both of the input channels. In this mode, the Y axis represents voltage and the X axis represents time. Note that only when this mode is enabled can Delayed Sweep be turned on.
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. 3 To Set the Horizontal System As shown in the figure above, the distances from the crossing points of axis and the circle to the origin of the coordinates are approximately equal. Thus, the phase deviation angle θ=±arcsin1=90°. Note: In Y-T mode, the oscilloscope could use any sample rate (within the guaranteed range) to capture waveform. The maximum sample rate of X-Y mode is 1.0 GSa/s. Generally, reducing the sample rate properly could improve the display effect of Lissajous figure.
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 and the waveform horizontal position and trigger control are not available. The range of horizontal scale adjustment is from 200.0 ms to 1000 s. Note: When Roll mode is enabled, 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 3 To Set the Horizontal System Horizontal Scale 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. Turn HORIZONTAL SCALE to adjust the horizontal scale. Turn clockwise to reduce the horizontal scale and turn counterclockwise to increase.
3 To Set the Horizontal System RIGOL Horizontal Reference Horizontal reference is the reference position according to which the screen waveform expands or compresses horizontally when adjusting HORIZONTAL SCALE. In Y-T mode (this function is not available in X-Y mode and Roll mode), press MENU HorRef in the horizontal control area (HORIZONTAL) at the front panel to select the desired reference mode and the default is “Center”. 1.

RIGOL 4 To Set the Sample System Acquisition Mode The acquisition mode is used to control how to generate waveform points from sample points. Press Acquire Acquisition in the function menu 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 Acquisition continuously to switch the acquisition mode. Normal In this mode, the oscilloscope samples the signal at equal time interval to rebuild the waveform.
4 To Set the Sample System RIGOL The Waveform before Average: The Waveform after 256 Averages: DS2000A User’s Guide 4-3
RIGOL 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. In this mode, the oscilloscope can display all the pulses with pulse widths at least as wide as the sample period.
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 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. At this point, you can still use the vertical control and horizontal control to pan and zoom the waveform.
RIGOL 4 To Set the Sample System Sample Rate The sample rate of this oscilloscope is up to 2 GSa/s. Note that the sample rate is displayed in the status bar at the upper side of the screen and in the Sa Rate menu and can be changed by adjusting the horizontal time base (s/div) through HORIZONTAL SCALE or modifying the Memory Depth. The influence on the waveform when the sample rate is too low: 1.
RIGOL 4 To Set the Sample System 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.
RIGOL 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. DS2000A provides up to 56 Mpts memory depth (option) and 14 Mpts standard memory depth.
4 To Set the Sample System RIGOL 70kPoints, 700kPoints, 7MPoints and 28MPoints (option). In “Auto” mode, the oscilloscope selects the memory depth automatically according to the current sample rate. Antialiasing At slower sweep speed, the sample rate is reduced and a dedicated display algorithm is used to minimize the possibility of aliasing. Press Acquire Anti_Aliasing to enable or disable the antialiasing function. By default, antialiasing is disabled.
5 To Trigger the Oscilloscope RIGOL 5 To Trigger the Oscilloscope 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 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. Siganls input from CH1/CH2 and the [EXT TRIG] 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 input of the channel selected is enabled, the channel can work normally.
RIGOL 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 that the acquisition memory of the oscilloscope is a cyclic buffer and the new data would overwrite the old data until the acquisition finishes.
RIGOL 5 To Trigger the Oscilloscope the oscilloscope overflows the pre-trigger buffer and the first data put into the buffer is first pushed out (First Input First Out, FIFO). When a trigger is found, the pre-trigger buffer would contain the data acquired just before the trigger. If no trigger is found, the oscilloscope will trigger forcefully.
5 To Trigger the Oscilloscope RIGOL Trigger Coupling Trigger coupling decides which kind of components will be transmitted to the trigger circuit. 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 8 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 5 To Trigger the Oscilloscope Trigger Holdoff Trigger holdoff can be used to stably trigger the complex waveforms (such as pulse series). Holdoff time is the amount of time that the oscilloscope waits before re-arming the trigger circuitry. The oscilloscope will not trigger until the holdoff time expires.
5 To Trigger the Oscilloscope RIGOL Noise Rejection Noise Rejection adds additional hysteresis to the trigger circuitry. Noise rejection reduces the possibility of noise trigger but also reduces the trigger sensitivity; therefore, a larger signal is required to trigger the oscilloscope. Press MENU Setting Noise Reject in the trigger control area (TRIGGER) at the front panel to enable or disable noise rejection.

16 Troubleshooting RIGOL 16 Troubleshooting The commonly encountered failures and their solutions are listed below. When you encounter those problems, please solve them following the corresponding steps. If the problem remains still, please contact RIGOL and provide your device information (Utility System System Info). 1. The screen is still dark (no display) after power on: (1) Check whether the power is correctly connected. (2) Check whether the power switch is really on.
RIGOL 16 Troubleshooting (3) Check the trigger level: adjust the trigger level to the middle of the signal. (4) Change the trigger holdoff setting. 5. No display after pressing RUN/STOP: Check whether the MODE at the trigger panel (TRIGGER) is on “Normal” or “Single” and whether the trigger level exceeds the waveform range. If yes, set the trigger level to the middle or set the MODE to “Auto”. Note: Using AUTO could automatically finish the above setting. 6.
