Description
The isolator has an internal load connected to an RF
detector (sensor), the output from the sensor is continually
monitored by the sttion for a fault conditon (high VSWR).
Once the station detects a sensor voltage above the threshold
the transmitter is automatically de-keyed and a FAULT con-
dition is reported.
IMPORTANT:
ANTENNA SWITCH
19B235897P2
DO NOT USE ISOLATOR WITHOUT CONNECTING THE SENSOR TO THE STATION
WARNING
ISOLATOR
344A3406P1
The sensor output must be connected to
P108 on the Interface Board when the Iso-
lator is used, failure to make this connection
with the Isolator installed will cause the
isolator to be damaged under high VSWR
conditions.
