Connectors

MODULATION INPUT

This connector provides an external modulation connection to the RF Generator.

Operating Considerations

Input impedance = 600Ω

Maximum input level = 12 V peak

Full scale input = 1 V peak

The Mod In To field of the RF GENERATOR screen sets the type of modulation (AM or FM) and sensitivity (%AM/Vpk or kHz/Vpk) for this connection.

The FM Coupling field in the RF GENERATOR, DUPLEX TEST, and various encoder modes selects ac or dc coupling of this signal for FM operation.

PAGING CHANNEL LOGGING (DCS2>)

The Paging Channel Logging port provides for logging protocol signaling from the Paging channel. Refer to Protocol Logging in the Application Guide.
