:TRIGger:HOLDoff:MODE
Command
:TRIGger:HOLDoff:MAX {FIXed | RANDom}
The Fixed mode sets the amount of time that the oscilloscope waits before
re- arming the trigger circuitry. It can be used to stabilize the display of
complex waveforms.
The RANDom mode varies the trigger holdoff from one acquisition to
another by randomizing the time values between triggers. The randomized
values can be between the values specified by the :TRIGger:HOLDoff:MAX
and :TRIGger:HOLDoff:MIN commands.
The Random holdoff mode ensures that the oscilloscope re- arms after each
acquisition in a manner that minimizes or eliminates the likelihood of
triggering at the beginning of a DDR burst. Randomizing the holdoff
increases the likelihood that the oscilloscope will trigger on different data
phases of a multiphase (8 data transfer) burst. This mode mixes up the
traffic pattern the oscilloscope triggers on and is very effective when used
on repeating patterns.
Query
:TRIGger:HOLDoff:MODE?
The query returns the current holdoff mode.
