4 To Set the Sample System RIGOL 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.
Page 81: Sample Mode
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.

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.
Page 87: To Trigger The Oscilloscope
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 guarrantee 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.
Page 88: Trigger Source
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.
Page 89: Trigger Mode
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.
Page 90 5 To Trigger the Oscilloscope RIGOL 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.
Page 91: Trigger Coupling
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.
Page 92: Trigger Holdoff
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.
Page 93: Noise Rejection
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.
