27 :TRIGger Commands
:TRIGger:HOLDoff
(see page 798)
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.
