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 Waveform Invert Vertical Scale Vertical Expansion Amplitude Unit Channel Label Delay Calibration DS2000 User’s Guide 2-1
RIGOL 2 To Set the Vertical System To Enable the Channel DS2000 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 Set the coupling mode to filter out the undesired signals. 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 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.
RIGOL 3 To Set the Horizontal System X-Y Mode In this mode, the oscilloscope changes the two channels from voltage-time display mode to voltage-voltage display mode. Wherein, the X axis and Y axis tracks the voltages of CH2 and CH1 respectively. The phase deviation between two signals with the same frequency can be easily measured via Lissajous method. The figure below shows the measurement schematic diagram of the phase deviation.
RIGOL 3 To Set the Horizontal System monitor the input and output signals of the circuit. Application example: measure the phase deviation of the input signals of two channels.

SCALE to ajdut the Press AUTO and enable X-Y mode.
3 To Set the Horizontal System RIGOL 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. When X-Y mode is enabled, “Delayed Sweep” will be disabled automatically.
RIGOL 3 To Set the Horizontal System 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 1.000 ks. 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 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 DS2000 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 SCALE or modifying the memory depth. HORIZONTAL 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. DS2000 provides up to 56 Mpts memory depth (option) and 14 Mpts standard memory depth.
4 To Set the Sample System RIGOL 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. The displayed waveforms will be more susceptible to aliasing when this function 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. MENU 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 Auto: No matter whether the trigger condition is met, there is always waveform display. A horizontal line is displayed when no signal is input. In this mode, the oscilloscope operates by first filling the pre-trigger buffer. It starts searching for a trigger after the pre-trigger buffer is filled and continues to flow data through this buffer while it searches for the trigger.
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.
