Trigger
Trig Slope
Controls the trigger polarity. It is set positive to trigger on a rising edge and negative to trigger on a
falling edge.
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, Line
Remote Command: :TRIGger[:SEQuence]:LINE:SLOPe POSitive|NEGative
:TRIGger[:SEQuence]:LINE:SLOPe?
Example: TRIG:LINE:SLOP NEG
Preset: POSitive
State Saved: Saved in instrument state
Backwards Compatibility Notes: The legacy :TRIGger[:SEQuence]:SLOPe command affects the slopes for the
VID, LINE, EXT1, EXT2, and RFB triggers.

Remote Command: :TRIGger[:SEQuence]:LINE:DELay <time>
:TRIGger[:SEQuence]:LINE:DELay?
:TRIGger[:SEQuence]:LINE:DELay:STATe OFF|ON|0|1
:TRIGger[:SEQuence]:LINE:DELay:STATe?
Example: TRIG:LINE:DEL:STAT ON
TRIG:LINE: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.
