Keeps the transmitter running if the R&S NetCCU800 fails

Controls data exchange between the R&S NetCCU800 and other components via CAN
bus

Monitors the outlet air temperature

Acquires measured data about the intake and outlet air temperatures

Transfers messages

Accepts and outputs rack commands (e.g. transmitter ON -> amplifier ON, cooling sys-
tem ON)

Configures the test points (mode-dependent)

Switches off the rack in the event of malfunction (e.g. fan failure)
The following equipment and modules can be connected to the rack controller:

R&S NetCCU800 via CAN bus

Exciters (1 or 2)

External cooling system (liquid-cooled transmitters)

Amplifier stages (1 or 2)

