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 Input Impedance Waveform Invert Vertical Scale Vertical Expansion Amplitude Unit Channel Label Delay Calibration DS4000 User’s Guide 2-1
2 To Set the Vertical System RIGOL To Enable the Channel DS4000 provides four analog input channels (CH1 to CH4) and provides independent vertical control system for each channel. As the vertical system setting methods of the four 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 Bandwidth Limit Set the bandwidth limit to reduce display noise. For example, the signal under test is a pulse with high frequency oscillation. When bandwidth limit is disabled, the high frequency components of the signal under test can pass the channel. Enable bandwidth limit and limit the bandwidth to 20 MHz, 100 MHz or 200 MHz, the high frequency components that exceed 20 MHz, 100 MHz or 200 MHz are blocked.

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 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 DS4000 is 4 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 Sample refers to the process that the oscilloscope converts analog signals to digital signals at a certain time interval and stores the data in order. Sample rate is the reciprocal of the time interval. Sample Rate 1 /Δ t The sample rate of this oscilloscope is up to 4 GSa/s.
4 To Set the Sample System 3. RIGOL Waveform Leakage: when the sample rate is too low, the waveform rebuilt from the sample data does not reflect all the actual signal information.
4 To Set the Sample System RIGOL 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. DS4000 provides up to 140 M points 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 During work, the oscilloscope samples waveform data continuously no metter whether the trigger is stable, but only stable trigger can garrantee stable display. The trigger circuit guarantees that each sweep or sample starts from the trigger condition defined by users on the input signal, namely each sweep and sample are synchronous and the waveforms acquired overlap to display stable waveform.
5 To Trigger the Oscilloscope RIGOL 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 to CH4 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 to CH4 can all be used as the trigger source. No matter whether the input of the channel selected is enabled, the channel can work normally.
5 To Trigger the Oscilloscope RIGOL 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 in the acquisition memory is determined by the reference time point and the delay setting. Trigger Event Pre-trigger Buffer Post-trigger Buffer Acquisition memory Pre-trigger/Delayed trigger: Acquire data before/after the trigger event.
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 5 kHz). HF reject: reject the high frequency components (higher than 50 kHz).
5 To Trigger the Oscilloscope RIGOL Trigger Holdoff Trigger holdoff can be used to stabilize the display of 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 greater amplitude waveform 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.
