2.4.2 AGC voltage relating to Gain - The 1200-05 IF Processor operates over a 0 to -80 dBm input range
on the RX IF side. The Automatic Gain Control (AGC) provides a constant -30 dBm +5, -15 dBm output RX
IF level over the entire input range. Pin 7 of the DB9 control connector, J105, can be monitored to determine
the approximate input level (and corresponding gain) in AGC as Table 2.2 shows.
