Test setup
Connect the power sensor cable to the USB port of R&S Cable Rider ZPH. If the power
sensor is having the binder connector (i.e R&S FSH-Z14, R&S FSH-Z44), the FSH-
Z144 adaptor cable is needed. Insert the directional power sensor between the source
and the load.
The power sensors for the R&S Cable Rider ZPH have an asymmetrical 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).
1 = Directional power sensor R&S FSH-Z14 or Z44
2 = Source
3 = Load
4 = USB binder adaptor (R&S FSH-Z144)
5 = USB port connector
Measuring the power
1. Press the MODE key.
2. Select the "Power Meter" softkey.
As soon as the R&S Cable Rider ZPH recognizes the power sensor, it displays the
