Using the power sensor as an external trigger
If activated, the power sensor creates a trigger signal when a power higher than the
defined "External Trigger Level" is measured. This trigger signal can be used as an
external power trigger by the R&S
FSMR3000.
This setting is only available in conjunction with a compatible power sensor.
Remote command:
[SENSe:]PMETer<p>:TRIGger[:STATe]
TRIG:SOUR PSE
, see
External Trigger Level ← Using the power sensor as an external trigger
Defines the trigger level for the power sensor trigger.
For details on supported trigger levels, see the data sheet.
Remote command:
[SENSe:]PMETer<p>:TRIGger:LEVel
Hysteresis ← Using the power sensor as an external trigger
Defines the distance in dB to the trigger level that the trigger source must exceed
before a trigger event occurs. Setting a hysteresis avoids unwanted trigger events
caused by noise oscillation around the trigger level.
Remote command:
[SENSe:]PMETer<p>:TRIGger:HYSTeresis
Trigger Holdoff ← Using the power sensor as an external trigger
Defines the minimum time (in seconds) that must pass between two trigger events.
Trigger events that occur during the holdoff time are ignored.
Remote command:
[SENSe:]PMETer<p>:TRIGger:HOLDoff
Drop-Out Time ← Using the power sensor as an external trigger
Defines the time the input signal must stay below the trigger level before triggering
again.
Slope ← Using the power sensor as an external trigger
Defines whether triggering occurs when the signal rises to the trigger level or falls
down to it.
Remote command:
[SENSe:]PMETer<p>:TRIGger:SLOPe
