8.1 Using a Power Sensor
The power sensor function turns the R&S Cable Rider ZPH into a wideband power
meter. It then always measures the power of the whole signal in the frequency range of
the power sensor. In most cases, the signal shape has no effect on the measurement.
The R&S Cable Rider ZPH supports the following power sensors.

cable identified by FSH-Z144 (USB to binder adapter) is required to connect these sen-
sors on the USB port. This FSH-Z144 is an RS232 to USB converter cable.
