8 Trigger
8.1 Trigger
IQMag | IDEMod | QDEMod | IINPut | QINPut | AIQMag | PXI | INTernal
Example
:TRIG:VID:DEL:STAT ON
:TRIG:VID:DEL 100 ms
Dependencies Only appears when Video, Line, External 1|2, RF Burst, Periodic Timer or an I/Q trigger is selected as
the Trigger Source
Couplings When FMT Trigger Criteria is INSIDE or OUTSIDE, FMT Trigger Delay State is forced to OFF
FMT Trigger Delay MaxValue is dependent on the current AcquisitionTime. The equation is: MaxValue
= 2^16 x AcqTime, but never to exceed 70 sec. Ex: In PVT View with a min PVT Acq Time of 200 us, this
Trigger Delay MaxValue is 13.26 sec. In RT Spectrum and Spectrogram with a min Acq Time of 100 us,
this Trigger Delay MaxValue is 6.55 sec. When the Acq Time is increased, this MaxValue also increases

:TRIGger[:SEQuence]:IF:DELay
:TRIGger[:SEQuence]:DELay
The legacy :TRIGger[:SEQuence]:DELay command affects the delay for the VID, LINE,
EXT1, EXT2, and RFB triggers
