29 :TRIGger Commands

:TRIGger:HOLDoff

(see page 790)

Command Syntax

:TRIGger:HOLDoff <holdoff_time>

<holdoff_time> ::= 60 ns to 10 s in NR3 format

The :TRIGger:HOLDoff command defines the holdoff time value in seconds.

Holdoff keeps a trigger from occurring until after a certain amount of time

has passed since the last trigger. This feature is valuable when a waveform

crosses the trigger level multiple times during one period of the waveform.

Without holdoff, the oscilloscope could trigger on each of the crossings,

producing a confusing waveform. With holdoff set correctly, the

oscilloscope always triggers on the same crossing. The correct holdoff

setting is typically slightly less than one period.

Query Syntax

:TRIGger:HOLDoff?

The :TRIGger:HOLDoff? query returns the holdoff time value for the

current trigger mode.

Return Format

<holdoff_time><NL>

<holdoff_time> ::= the holdoff time value in seconds in NR3 format.
