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.

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.
