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 680
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 681
7.3.2.3 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 7.3.2.2, "Power Sensor Set-
tings", on page 366.
The remote commands required to perform these tasks are described in Chap-
ter 8.8.5.2, "Working with Power Sensors", on page 671.
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 373.
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.
1. To display the "Power Sensor" tab of the "Input" dialog box, do one of the following:
● Select "Input" from the "Overview" .
● Select the INPUT/OUTPUT key and then the "Power Sensor Config" softkey.
2. Select the tab for the power sensor index you want to configure, e.g. "Power Sen-
sor 1" .
3. Press "Select" to analyze the power sensor data according to the current configura-
tion when power measurement is activated.
4. From the selection list with serial numbers of connected power sensors, select the
sensor you want to configure.
