How to Zero the Power Sensor
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 that is assigned to the power sensor you want to zero.
3. Press the "Zeroing Power Sensor" button.
A dialog box is displayed that prompts you to disconnect all signals from the input
of the power sensor.
4. Disconnect all signals sending input to the power sensor and press [ENTER] to
continue.
5. Wait until zeroing is complete.
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.
