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.

TRIG:EXT1:SLOP NEG
This same slope is used in the Ext1 selection for the trigger source in the Trigger menu and for the
period timer sync source (in the Trigger menu and in the Gate Source menu).

:TRIGger[:SEQuence]:EXTernal:SLOPe
For backward compatibility, the parameter EXTernal is mapped to EXTernal1
:TRIGger[:SEQuence]:FRAMe:EXTernal1:SLOPe
The legacy :TRIGger[:SEQuence]:SLOPe command affects the slopes for the VID, LINE, EXT1, EXT2,
and RFB triggers.

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.
