Remote Operation 5-93
TRIGger:DELay
Description: Set or return the trigger delay time in seconds with respect to the trigger. Positive values cause the
actual trigger to occur after the trigger condition is met. This places the trigger event to the left of
the trigger point on the display, and is useful for viewing events during a pulse, some fixed delay
time after the rising edge trigger. Negative trigger delay places the trigger event to the right of the
trigger point on the display, and is useful for looking at events before the trigger edge.
Syntax: TRIGger:DELay
Argument: Timebase Trigger Delay
5 nsec/div to 500 nsec/div -4 msec to +100 msec
1 usec/div to 10 msec/div 4000 divisions
20 msec/div to 3600 sec/div -40 to +100 sec
Valid Modes: Pulse and gated Statistical modes only
TRIGger:FASTtrig
Description: Set or return the Fast Trigger mode status.
Syntax: TRIGger:FASTtrig
Argument: = {OFF, ON}
Valid Modes: Pulse and gated Statistical modes only
TRIGger:HOLDoff
Description: Set or return the trigger holdoff time in seconds. Trigger holdoff is used to disable the trigger for
a specified amount of time after each trigger event. The holdoff time starts immediately after each
valid trigger edge, and will not permit any new triggers until the time has expired. When the
holdoff time is up, the trigger re-arms, and the next valid trigger event (edge) will cause a new
sweep. This feature is used to help synchronize the power analyzer with burst waveforms such as
a TDMA or GSM frame. The trigger holdoff resolution is 10 nanoseconds, and it should be set to
a time that is just slightly shorter than the frame repetition interval.
Syntax: TRIGger:HOLDoff
Argument: = 0 to 1.00000000 seconds in 10 nsec increments, 0.0 = no holdoff
Valid Modes: Pulse and gated Statistical modes only
