ISOMET
Gate (active high enables the RF amplifier)
TTL compatible input
Default condition is RF Off.
A high level (1.7V < V < 5V) will gate the RF
ON
.
A low level (0V < V < 0.8V), or not connected will gate the RF
OFF.
Analog Modulation (0 - 10V)
Provides high speed proportional amplitude control of the RF output.
Lower limit: an input voltage of less than 0.4V will drive the RF Off.
Upper limit: an input of 10V will result in the maximum RF output,
(For RFA2120D type, modulation control is On:Off and requires a 5V CMOS / TTL compatible input).
The amplitude level is defined by the selected RF power adjustment POT.
RF Power Adjustment (POT set level)
The maximum RF power limit is set using a manual adjust multi-turn potentiometer ‘PWR ADJ’.
Maximum RF power = fully clockwise
