How to Configure a Power Sensor as an External (PSE) Trigger
The following step-by-step instructions demonstrate how to configure a power sensor
to be used as an external power sensor trigger.
To configure a power sensor as an external power sensor (PSE) trigger
1. Connect a compatible power sensor to the "Power Sensor" interface on the front
panel of the R&S
FSW. (For details on supported sensors see
Sensor as an External Power Trigger"
2. Set up the power sensor as described in
"How to Set Up a Power Sensor"
3. In the "Power Sensor" tab of the "Input" dialog box, select the "External Power Trig-
ger" option.
4. Enter the power level at which a trigger signal is to be generated ("External Trigger
Level") and the other trigger settings for the power sensor trigger.
5. Press the [TRIG] key and then select "Trigger/ Gate Config".
6. In the "Trigger And Gate" dialog box, select "Signal Source" = "PSE".
The R&S
FSW is configured to trigger when the defined conditions for the power
sensor occur. Power measurement results are provided as usual.

Optional External Generator Control
If the R&S
FSW optional External Generator Control is installed, you can operate vari-
ous commercially available generators as an external generator with the R&S
FSW.
Thus, scalar network analysis with the R&S
FSW is possible.
