A corresponding message is displayed.

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 "Using a Power

Sensor as an External Power Trigger" on page 374).

2. Set up the power sensor as described in "How to Set Up a Power Sensor"

on page 379.

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.

8.2.4 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.
