Transmitter/Regenerative Translator Turn On Procedure
Instruction Manual, Rev. 2 83
NOTE: The RF System Interlock is provided on J12, a 15 position “D” connector, located on
the rear panel of the CU0TD-1 thru CU0TD-5 drawer. The RF System Interlock at J12-5
provides the customer with a means of connecting the system to protection circuits, for the
loads, thermal switches, combiners, or the antenna, in the output of your system, that will
place the system in Standby if the protection circuit opens.
The Reject Load Interlock is provided at J11, a 9 position “D” connector. J11-6 provides the
customer with a means of connecting the system to protection circuits, for the reject load in
multiple amplifier systems, which will place the system in Standby if the protection circuit
opens. If the interlocks are not used in your system, a plug with a jumper from J12-5 to
J12-15, ground, for RF system Interlock and another plug with a jumper from J11-6 to J11-
9, for Reject Load Interlock, need to be connected. These jumpers provide the RF System
and Reject Load Interlocks, which allow the system to go to operate. Without the jumpers,
the system will remain in Standby.
Adaptive Pre-Correction Set-up Procedure
Adaptive Pre-correction is available as limited One-Touch Correction (OTC) or full feature
correction. With One-Touch correction the adaptive process can be enabled for one cycle
whereas full feature correction can be set to continuously adapt or automatically adapt
when performance characteristics indicate that a change is needed.
Please refer to the Web GUI section Digital Adaptive Pre-corrector for full details.
