SWE:EGAT:SOUR EXT for gated triggering, see [SENSe:]SWEep:EGATe:SOURce
on page 1060
Video ← Trigger Source
Defines triggering by the video signal, i.e. the filtered and detected version of the input
signal (the envelope of the IF signal), as displayed on the screen.
Define a trigger level from 0 % to 100 % of the diagram height. The absolute trigger
level is indicated by a horizontal trigger line in the diagram, which you can also move
graphically to change the trigger level.
A fixed hysteresis of ±5 % of the specified trigger value (in V) is applied to the video
trigger level automatically and cannot be changed.
Video mode is only available in the time domain, and not for I/Q-based data.
Remote command:
TRIG:SOUR VID, see TRIGger[:SEQuence]:SOURce on page 1053
SWE:EGAT:SOUR VID for gated triggering, see [SENSe:]SWEep:EGATe:SOURce

IF Power ← Trigger Source
The R&S FSW starts capturing data as soon as the trigger level is exceeded around
the third intermediate frequency.
For frequency sweeps, the third IF represents the start frequency. The trigger band-
width at the third IF depends on the RBW and sweep type.
For measurements on a fixed frequency (e.g. zero span or I/Q measurements), the
third IF represents the center frequency.
This trigger source is only available for RF input.
The available trigger levels depend on the RF attenuation and preamplification. A refer-
ence level offset, if defined, is also considered.
For details on available trigger levels and trigger bandwidths, see the data sheet.
Note: Be aware that in auto sweep type mode, due to a possible change in sweep
types, the trigger bandwidth can vary considerably for the same RBW setting.
Remote command:
TRIG:SOUR IFP, see TRIGger[:SEQuence]:SOURce on page 1053
SWE:EGAT:SOUR IFP for gated triggering, see [SENSe:]SWEep:EGATe:SOURce
on page 1060
Baseband Power ← Trigger Source
Defines triggering on the baseband power (for baseband input via the optional Digital
Baseband Interface or the optional Analog Baseband interface).
Remote command:
TRIG:SOUR BBP, see TRIGger[:SEQuence]:SOURce on page 1053
RF Power ← Trigger Source
Defines triggering of the measurement via signals which are outside the displayed
measurement range.
