Trigger
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.

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.

RF Burst
Pressing this key, when it is not selected, selects the RF Burst as the trigger. A new
sweep/measurement will start when an RF burst envelope signal is identified from the signal at
the RF Input connector. Pressing this key, when it is already selected, accesses the RF Burst
trigger setup menu.
In some models, a variety of burst trigger circuitry is available, resulting in various available
burst trigger bandwidths. The analyzer automatically chooses the appropriate trigger path based
on the hardware configuration and other settings of the analyzer.

dependencies
The Status Operation Register bit 5 "Waiting for Trigger" is set at the same time as the Sweeping
or Measuring bit is set. It is cleared when the trigger actually occurs (that is, after the trigger
event occurs and all the applicable trigger criteria have been met). A corresponding pop-up
message ("Waiting for trigger") is generated if no trigger signal appears after approximately 2
sec. This message goes away when a trigger signal appears.
