IF Power/BB Power ← Trg/Gate Source
Defines triggering of the measurement using the second intermediate frequency.
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 depends on the RBW and sweep type:
Sweep mode:
●
RBW > 500 kHz: 40 MHz, nominal
●
RBW ≤ 500 kHz: 6 MHz, nominal
FFT mode:
●
RBW > 20 kHz: 40 MHz, nominal
●
RBW ≤ 20 kHz: 6 MHz, nominal
Note: Be aware that in auto sweep type mode, due to a possible change in sweep
types, the bandwidth may vary considerably for the same RBW setting.
The R&S FSVA/FSV is triggered as soon as the trigger level is exceeded 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.
For digital input via the R&S Digital I/Q Interface (R&S FSV-B17), the baseband power
("BB Power") is used as the trigger source.
IF power triggers are not available together with the bandwidth extension option
R&S FSV-B160.

TRIG:SOUR IFP, see TRIGger<n>[:SEQuence]:SOURce on page 909
TRIG:SOUR BBP for digital input

Power Sensor ← Trg/Gate Source
Uses an external power sensor as a trigger function. This option is only available if the
R&S FSV-K9 Power Sensor option is installed and a power sensor is connected and
configured.
(See Chapter 3.9, "Instrument Functions - Power Sensor (R&S FSV-K9)",
on page 538.)
Power sensors are configured in the "Input/Output" menu, see Chapter 3.9.3, "Config-
uring an External Power Trigger", on page 543.
