R301 RF POWER SUPPLY OPERATOR’S MANUAL

When in Slave mode, the R301 RF Power Supply uses the common exciter input as its

frequency source.

7. Fan Exhaust

Keep fan exhaust free of obstructions, dust and dirt.

When the R301 RF Power Supply is mounted in an enclosure or

equipment rack, ensure there is an adequate air intake and hot air exhaust.

Operating the R301 at elevated temperatures or reduced airflow for long

periods of time may degrade its reliability and/or void the warranty.

8. Analog Interface Connector

The analog interface connector is located on the rear panel of the R301 Radio Frequency

Power Supply. Connector type: 25-pin female “D” sub-miniature. Control and status

signals for the RF Power Supply are available on this connector. See the table below for

descriptions of the interface connector signals.

Note:

GND, FWDRET, REFRET, FBRET, and SETRET must be referenced at the

user’s system or the unit will not operate properly

The RF Power Supply responds to input from the Analog interface when ANALOG

control has been selected. The Mains Interlock (pins 1 and 14) and External Interlock

(pins 2 and 15) are active regardless of control method selected.

Asterisk (*) denotes an active-low signal
