Remote command:
[SENSe:]PMETer<p>:TRIGger:LEVel on page 1117
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 on page 1116
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 on page 1116
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 on page 1117
8.2.3.3 How to Work With a Power Sensor
The following step-by-step instructions demonstrate how to set up a power sensor. For
details on individual functions and settings see Chapter 8.2.3.2, "Power Sensor Set-
tings", on page 375.
The remote commands required to perform these tasks are described in Chap-
ter 14.7.6.5, "Working with Power Sensors", on page 1107.
Power sensors can also be used to trigger a measurement at a specified power level,
e.g. from a signal generator.
This is described in "How to Configure a Power Sensor as an External (PSE) Trigger"
on page 381.
How to Set Up a Power Sensor
Up to 4 external power sensors can be configured separately and used for precise
power measurement. All power sensors can be activated and deactivated individually.
The following procedure describes in detail how to configure and activate power sen-
sors.
