The table below explains the user-selectable parameters in detail:
Select Outputstage A/B > Setup > Rack Setup > Rack 1 > Rack Controller.
The Rack Controller window opens.
Setting Explanation
Racks per OS Number of racks belonging to the output stage
Outlet Temp. Fault Switch-off threshold with overtemperature
If this threshold is exceeded, the rack controller shuts down the transmit-
ter rack.
Value: 45 °C to 65 °C
Nominal value: 65 °C
Outlet Temp. Warning Warning threshold for overtemperature
A warning is generated if this threshold value is exceeded.
Sum Probe at Rack Used to select the transmitter rack (rack controller) to which the test
points for forward/reflected power of the entire output stage are con-
nected
Only with active and passive output-stage standby
Independent Racks Possibility of dividing the output stage logically into independent racks
– no: All racks of the output stage are controlled together and all act on
the same RF output (default setting).
– yes: The racks of the output stage can have separate RF outputs and
can be controlled individually (e.g. ON/OFF command).
