R&S FSH Working with Power Sensors
Using a Directional Power Sensor
Operating Manual 1309.6275.12 - 14 118
3.2.1 Connecting a Directional Power Sensor
The R&S FSH controls and powers the directional power sensors via a special
interface on the top of the instrument.
Connect the power sensor cable to the power sensor interface and screw it into
position. The power sensor itself is located between the source and the load of the test
setup. The figure below shows the way a test setup would look like.
The power sensors for the R&S FSH have an assymetrical design. Hence, you have to
insert them into the test setup in such a way that the "Forward" arrow (1 2) on the
sensor points toward the load (= in the direction of the power flux).
If the R&S FSH recognizes a power sensor, it sets up a connection via the interface
and after a few seconds shows the results. It displays the type of the power sensor in
the display header. If an error occurs, the R&S FSH shows a corresponding message.

3.2.2 Performing and Configuring Measurements
After you have connected a power sensor, the R&S FSH immediately starts to
measure the signal power.
When measuring high powers, pay strict attention to the following instructions to avoid
personal injury and to prevent the power sensor from being destroyed
