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 10 % 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.

IF Power ← Trigger Source
The R&S FSV/A 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 threshold
depends on the defined trigger level, as well as on the RF attenuation and preamplifi-
cation. A reference level offset, if defined, is also considered. The trigger bandwidth at
the intermediate frequency depends on the RBW and sweep type. For details on avail-
able trigger levels and trigger bandwidths, see the instrument data sheet.
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.

I/Q Power ← Trigger Source
This trigger source is only available in the I/Q Analyzer application and in applications
that process I/Q data.
If the R&S FSV3-B1000/-B600 bandwidth extension option is active, this trigger is not
available for bandwidths
≥
400 MHz.
