3.9.1 Using Power Sensors
Up to 4 external power sensors can be configured separately and used for precise
power measurement, as a trigger, or both. All power sensors can be activated and
deactivated individually.
The following procedure describes in detail how to configure and activate power sen-
sors.
For details on the settings in the "Power Sensor Configuration" dialog box, see Chap-
ter 3.9.5, "Power Sensor Configuration Dialog", on page 547.
1. Press INPUT/OUTPUT > "Power Sensor" to display the "Power Sensor" menu.
2. Press "Power Sensor Config" to display the configuration dialog box.
3. Select the tab for the power sensor index you want to configure, e.g. "Sensor 1".
Note: if automatic assignment is active (default) and a power sensor is already
connected to the R&S FSVA/FSV, the serial number of the sensor is indicated in
one of the tabs. In this case, you configure that particular sensor in the correspond-
ing tab. If no serial number is indicated, you can set up a configuration and assign
a sensor manually later.
4. Press "Select" to evaluate the power sensor when power measurement is activa-
ted.
5. Define the frequency of the signal whose power you want to measure.
a) To define the frequency manually, select "Frequency Manual" and enter a fre-
quency.
b) To determine the frequency automatically, select "Frequency Coupling" and
then either "Center", to use the center frequency, or "Marker", to use the fre-
quency defined by marker 1.
6. Select the "Unit" for the power result display.
