Remote command:
TRIG:SOUR GP0, see TRIGger<n>[:SEQuence]:SOURce on page 909
SWE:EGAT:SOUR RFP for gated triggering, see [SENSe:]SWEep:EGATe:SOURce
on page 854
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 on page 908
TRIGger<n>[:SEQuence]:LEVel:VIDeo on page 908
For digital input via the R&S Digital I/Q Interface, R&S FSV-B17:
TRIGger<n>[:SEQuence]:LEVel:BBPower on page 907
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"
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.
"Neg"
Edge triggering: the sweep is continued on a "0" to "1" transition for
the gate length duration after the gate delay time has elapsed.

Trigger Offset
Opens an edit dialog box to enter the time offset between the trigger signal and the
start of the sweep.
offset > 0: Start of the sweep is delayed
offset < 0: 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
max
= sweep time
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.
See Table 3-15.
