7 Cable and Antenna Test Mode
The cable and antenna test (CAT) mode provides functionality to measure cables and
antennas of transmission equipment in wireless telecommunication systems.
In a perfect system, the signal would arrive at the antenna without any losses and be
transmitted with the required power and frequency. In reality, however, you can
encounter many possible mechanical defects in the system that cause a deterioration
of the transmission quality. See
for the typical defects in a transmission sys-
tem.

The R&S Cable Rider ZPH provides the necessary functionality to test the system
equipment for its characteristics and identify faults when it is being installed or main-
tained.
