Bringing Up RF Output: Individual PA Cabinets
STEP 1
Turn OFF the circuit breakers on all but the first PA Cabinet (if more
than one).
STEP 2
To monitor the cabinet power output the following 2 methods should be
used.
a.
Connect a power meter to a precision coupler in the cabinet output
line before any filters or combiner. The coupling factor should be
printed on the side of the coupler line section. This number would be
entered into the power meter as the offset.
b.
Use the GUI to monitor the cabinet power output. This method does
not use a precision coupler, but it should have been calibrated in the
factory. PA Currents should also be monitored if this method is used.
These reading should be re-calibrated later.
STEP 3
Turn on the exciter circuit breaker. Lower the exciter(s) power to zero.
Turn ON the Driver A circuit breaker on the lower front of the Control
Cabinet. Verify that Driver A is selected on the GUI, (Transmitter
Control screen 4.0).
STEP 4
Press the ON button on the Control Cabinet front panel.
STEP 5
Turn ON PA Supply 1 (top left) on the PA Cabinet, corresponding to PA
Modules 1 and 2, see Figure 2-9. Verify that those modules are inserted
and communicating with the transmitter (no communication fault on the
GUI). Press the transmitter ON button to activate the modules.
