Connecting a Directional Power Sensor
The R&S Cable Rider ZPH controls and powers the directional power sensors via a
special interface on the top of the instrument.
Connect the power sensor cable via the USB to binder adapter to the USB port of R&S
Cable Rider ZPH. The power sensor itself is located between the source and the load
of the test setup.
For the test setup of the directional power sensor, see
"Test setup"
on page 84.
If the R&S Cable Rider ZPH 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 Cable Rider ZPH shows a
corresponding message.
