rier or adjacent channels, the R&S Cable Rider ZPH shows the powers of each chan-
nel in a list below the marker list. The channel itself is marked by red (transmission
channels) or green (adjacent channels) vertical lines.

The predefined standards are the same as for channel power measurements (3GPP
WCDMA, cdmaOne and CDMA2000 1x systems). However, you can also customize
the settings to set up the R&S Cable Rider ZPH for other radiocommunication stand-
ards. You can define the settings directly on the R&S Cable Rider ZPH or define and
manage them using the R&S InstrumentView software.
When customizing settings, make sure to consider the following points to get valid and
accurate measurement results:
●
Reference level
Make sure not to overload the R&S Cable Rider ZPH as the power is measured
with a resolution bandwidth that is small in comparison with the signal bandwidth.
As with channel power measurements, automatically set the reference to an opti-
mal level with the "Level Adjust" softkey.
