(-24dBm + RF Att ) ≤ Triggerlevel ≤ (+5dBm + RF Att), max. 30 dBm, for Preamp =
OFF

with
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.
Remote command:
TRIG:SOUR RFP, see
IF Power/BB Power ← Trg/Gate Source
For this purpose, the R&S FSV uses a level detector at the second intermediate fre-
quency.
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 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.
Remote command:
TRIG:SOUR IFP, see
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.
Power sensors are configured in the "Input/Output" menu, see "Configuring an External
Power Trigger" in the base unit description.
If a power sensor is selected as the trigger mode, the following softkeys are not availa-
ble; these settings are configured in the "Power Sensor Configuration" dialog box (see
the base unit description).
