RF Output
The RF output signal is available from an N-type connector.
4.10.3
25-Pin Connector
A 25-pin, D-shell (``D'') connector is mounted on the rear panel. It provides power
connections and a connection from the automatic level control (ALC) circuit. The pin
connections are given in table 1.
4.10.4
9-Pin Connector
A front-panel, 9-pin, D-shell connector provides analogue voltages for testing purposes.
