1. Select the "OFS" softkey.
The R&S Cable Rider ZPH opens an input field to define the reference offset.
2. Enter the offset you require.
The R&S Cable Rider ZPH takes the offset value into account in the power (level)
and matching results.
If high powers are applied that exceed the maximum input level of the R&S FSH-Z14
or R&S FSH-Z44, a directional coupler or an attenuator has to be connected ahead of
the power sensor.
In such cases, the coupling attenuation of the directional coupler or the attenuation
value of the attenuator are entered as positive dB values (see
condiion to set cable
attenuation
) into the R&S Cable Rider ZPH to ensure true measured power readout. In
both cases, a termination or an attenuator of sufficient power-handling capacity has to
be connected to the power sensor at the load end. The matching readout is irrelevant
in such case since it is likewise corrected by taking into account the attenuation value
of the termination or attenuator.
