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.
Key Path
Trigger, Line
Remote Command
:TRIGger[:SEQuence]:LINE:SLOPe POSitive|NEGative
:TRIGger[:SEQuence]:LINE:SLOPe?
Example
TRIG:LINE:SLOP NEG
Preset
POSitive

Backwards Compatibility
Notes
The legacy :TRIGger[:SEQuence]:SLOPe command affects the slopes for the VID, LINE, EXT1,
EXT2, and RFB triggers.
Initial S/W Revision
Prior to A.02.00
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:DELay
: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.
