    RIGOL Trigger Holdoff Use trigger Holdoff to stabilize a complex waveform, such as a pulse range. Holdoff time is the oscilloscope‟s waiting period before starting a new trigger. During Holdoff, oscilloscope will not trigger until Holdoff ends. For instance: To trigger on the first pulse on a group of them, users can set the holdoff time to Pulse cluster width.

  • Page 71: Trigger Source

    RIGOL Trigger Terms Explanation 1. Trigger Source: Trigger occurs from several sources: Input channels (CH1 and CH2), AC Line, Ext, Ext/5.  Input Channels: It is the most commonly used trigger source. The channel works when selected as a trigger source whatever displayed.
