A "Trigger Offset", "Trigger Polarity" and "Trigger Holdoff" (to improve the trigger stabil-
ity) can be defined for the RF trigger, but no "Hysteresis".
Remote command:
TRIG:SOUR RFP, see TRIGger[:SEQuence]:SOURce on page 854
SWE:EGAT:SOUR RFP for gated triggering, see [SENSe:]SWEep:EGATe:SOURce
on page 857
Power Sensor ← Trigger Source ← Trigger Settings
Uses an external power sensor as a trigger source. This option is only available if a
power sensor is connected and configured.
(See chapter 6.2.3.3, "How to Work With a Power Sensor", on page 328.)
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
(seechapter 6.2.3.2, "Power Sensor Settings", on page 324 ).
●
"Trigger Level" on page 430
●
"Slope" on page 432
●
"Hysteresis" on page 431
●
"Trigger Holdoff" on page 431
Note: For R&S power sensors, the "Gate Mode" Lvl is not supported. The signal sent
by these sensors merely reflects the instant the level is first exceeded, rather than a
time period. However, only time periods can be used for gating in level mode. Thus,
the trigger impulse from the sensors is not long enough for a fully gated measurement;
the measurement cannot be completed.
Remote command:
TRIG:SOUR PSE, see TRIGger[:SEQuence]:SOURce on page 854
SWE:EGAT:SOUR PSE for gated triggering, see [SENSe:]SWEep:EGATe:SOURce
on page 857
Time ← Trigger Source ← Trigger Settings
Triggers in a specified repetition interval.
Remote command:
TRIG:SOUR TIME, see TRIGger[:SEQuence]:SOURce on page 854
Trigger Level ← Trigger Settings
Defines the trigger level for the specified trigger source.
For gated measurements, this setting also defines the gate level.
For details on supported trigger levels, see the data sheet.
Remote command:
TRIGger[:SEQuence]:LEVel:IFPower on page 853
TRIGger[:SEQuence]:LEVel:IQPower on page 853

TRIGger[:SEQuence]:LEVel:RFPower on page 853
Repetition Interval ← Trigger Settings
Defines the repetition interval for a time trigger. The shortest interval is 2 ms.
