R&S FSV-K7/K7S
Note: The RF offline trigger is based on the I/Q data of the demodulated signal, limi-
ted to the demodulation bandwidth. For a wider trigger bandwidth and triggering based
on the currently measured RF input signal, use the more powerful
Remote command:
TRIG:SEQ:SOUR AM, see
Time ← Trigger Source
Opens an edit dialog box to define a repetition interval in which the measurement is
triggered. The shortest interval is 2 ms.
Remote command:
TRIG:SOUR
Trigger Level
Defines the trigger level as a numeric value.
In the trigger mode "Time", this softkey is not available.
Remote command:
TRIGger<n>[:SEQuence]:LEVel:IFPower
For digital input via the R&S Digital I/Q Interface, R&S FSV-B17:
TRIGger<n>[:SEQuence]:LEVel:BBPower
Trigger Polarity
Sets the polarity of the trigger source.
The sweep starts after a positive or negative edge of the trigger signal. The default set-
ting is "Pos". The setting applies to all modes with the exception of the "Free Run" and
"Time" mode.
"Pos"
"Neg"
Remote command:
TRIGger<n>[:SEQuence]:SLOPe
[SENSe:]SWEep:EGATe:POLarity
Trigger Offset
Opens an edit dialog box to enter the time offset between the trigger signal and the
start of the sweep. The time may be entered in multiples of 125 ns in the range -13 s to
13 s (default 0 s).
offset > 0:
offset < 0:

Level triggering: the sweep is stopped by the logic "0" signal and
restarted by the logical "1" signal after the gate delay time has
elapsed.
Edge triggering: the sweep is continued on a "0" to "1" transition for
the gate length duration after the gate delay time has elapsed.
