R&S FSV-K8
Trg/Gate Polarity
Sets the polarity of the trigger/gate 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 trigger modes with the exception of the "Free
Run", "Power Sensor" and "Time" mode.
"Pos"
"Neg"
Remote command:
TRIGger<n>[:​ S EQuence]:​ S LOPe​
Trigger Offset
Opens an edit dialog box to enter the time offset between the trigger signal and the
start of the sweep.
offset > 0:
offset < 0:
In the "External" or "IF Power" trigger mode, a common input signal is used for both
trigger and gate. Therefore, changes to the gate delay will affect the trigger delay (trig-
ger offset) as well.
Remote command:
TRIGger<n>[:​ S EQuence]:​ H OLDoff[:​ T IME]​
Trigger Hysteresis
Defines the value for the trigger hysteresis for "IF power" or "RF Power" trigger sour-
ces. The hysteresis in dB is the value the input signal must stay below the power trig-
ger level in order to allow a trigger to start the measurement. The range of the value is
between 3 dB and 50 dB with a step width of 1 dB.
Remote command:
TRIGger<n>[:​ S EQuence]:​ I FPower:​ H YSTeresis​
Trigger Holdoff
Defines the value for the trigger holdoff. The holdoff value in s is the time which must
pass before triggering, in case another trigger event happens.

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.

Start of the sweep is delayed
Sweep starts earlier (pre-trigger)
Only possible for span = 0 (e.g. I/Q Analyzer mode) and gated trigger
switched off
Maximum allowed range limited by the sweep time:
pretrigger = sweep time
max
When using the R&S Digital I/Q Interface (R&S FSV-B17) with I/Q Ana-
lyzer mode, the maximum range is limited by the number of pretrigger
samples.
