Power Meter
R&S Cable Rider ZPH option
R&S ZPH-K9 (order number: 1321.0415.02) option is required to operate the R&S
Cable Rider ZPH in the power meter mode.
For highly accurate power measurements, you can connect a power sensor to the R&S
Cable Rider ZPH and perform measurements.

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 power sensor measures the power in the frequency range defined in the data
sheet of the power sensor. This means that you can measure both sine signals and
modulated signals precisely over a large dynamic range.
For a complete list of supported power sensors, refer to the data sheet.
If you are using one of the NRP power sensors, you also need a passive USB adapter
(R&S NRP-Z4) to connect the power sensor to the R&S Cable Rider ZPH.
For more information on the characteristics of the supported power sensors, see the
following:
●
The datasheet of the R&S Cable Rider ZPH.

The website for R&S power sensors.
