500 MHz ≤ InputSignal ≤ 7 GHz
Note: If input values outside of this range occur (e.g. for fullspan measurements), the
sweep may be aborted and a message indicating the allowed input values is displayed
in the status bar.

IF Power ← Trigger Source
Defines triggering of the measurement via signals which are outside the measurement
channel.
For this purpose, the R&S FSVA/FSV uses a level detector at the second intermediate
frequency.
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.
The bandwidth at the intermediate frequency is 20 MHz. The R&S FSVA/FSV is trig-
gered as soon as the trigger level is exceeded within a 10 MHz range around the
selected frequency (= start frequency in the frequency sweep).
Thus, the measurement of spurious emissions, e.g. for pulsed carriers, is possible
even if the carrier lies outside the selected frequency span.
IF power triggers are not available together with the bandwidth extension option
