Trigger

Trig Delay

Controls a time delay during which the analyzer will wait to begin a sweep after meeting the
trigger criteria. You can use negative delay to pre-trigger the instrument in time domain or FFT,
but not in swept spans.

Key Path

Trigger, External 1

Remote Command

:TRIGger[:SEQuence]:EXTernal1:DELay <time>

:TRIGger[:SEQuence]:EXTernal1:DELay?

:TRIGger[:SEQuence]:EXTernal1:DELay:STATe OFF|ON|0|1

:TRIGger[:SEQuence]:EXTernal1:DELay:STATe?

Example

TRIG:EXT1:DEL:STAT ON

TRIG:EXT1:DEL 100 ms

Notes

Video trigger delay may be set to negative values, in time domain, FFT and even swept. It makes
intuitive sense in time domain and works well in FFT mode where the bandwidth of the filter
before the video trigger is about 1.25 span. In swept spans, negative settings of Trig Delay are
treated as a zero setting within the internal hardware and the advisory message "Neg. Trig Delay
unavailable in Swept Mode, zero delay used." is generated when such a delay is set.

Compatibility SCPI

:TRIGger[:SEQuence]:EXTernal:DELay

For backward compatibility, the parameter EXTernal is mapped to EXTernal1

Backwards Compatibility
Notes

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

The legacy :TRIGger[:SEQuence]:OFFSet command is supported for the VIDeo, LINE, EXT1, and
EXT2 triggers.

Prior to A.02.00

External 2

Pressing this key, when it is not selected, selects an external input signal as the trigger. A new
sweep/measurement will start when the external trigger condition is met using the external 2
input connector. The external trigger 2 input connector is on the rear panel.

Pressing this key, when it is already selected, accesses the external 2 trigger setup menu.
