Superior Broadcast ATVCA Amplier

5. Setting

5.1 Setting on air

1. Connect the RF output power of a suitable TV exciter (e.g. the DTVPE of

R.V.R. Elettronica) to the RF input (RF module) using a cable tted with N type

connectors. The exciter should be set to minimum output power and switched

OFF.

2. Connect the amplier’s INTERLOCK output connector to the exciter’s Interlock

input, if available (it is available in all RVR Elettronica exciters) using a twin

wire with BNC connectors.

Note: the amplier’s INTERLOCK output connector is an output signal on coaxial

BNC type connector. The operating logic is as follows: the internal conductor

is oating when the amplier works correctly, else is closed to GND. When

INTERLOCK signal is closed to GND, RF output power from exciter MUST shut

down.

3. Connect the RF output to the antenna system cable suitable to stands the

RF output power of the amplier (antenna system means RF ouput lter and

antenna feeder).

5.2 Setting on lab

1. Perform connections described in the previous chapter from point 1 to point

2. Connect the RF output to a dummy load suitable to stands the RF output power

of the amplier.
