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. The figure below shows some typical defects in a
transmission system.
The R&S ZVH provides the necessary functionality to test the system equipment for its
characteristics and identify faults when it is being installed or maintained. Each
measurement provides different aspects of the test you are performing.

Test setup
A typical test setup to test cables and antennas includes the R&S ZVH, an RF cable
(e.g. R&S FSH-Z320, order no. 1309.6600.00), a calibration standard (R&S FSH-Z28
or R&S FSH-Z29, order no. 1300.7804.03 and 1300.7504.03) and the cable under test.
Cable and antenna tests also require a tracking generator which is already part of the
R&S ZVH hardware. The tracking generator transmits a reference signal through the
internal VSWR bridge to the test port.
