2.4.2 AGC voltage relating to Gain
The 1200-07 IF AGC Amplifier operates over a 0 to -80 dBm input range. The Automatic Gain Control
(AGC) provides a constant -35 dBm ± 10 dBm output IF output level over the entire input range. The AGC
VOLTAGE BNC connector, J104, can be monitored to determine the approximate input level (and
corresponding gain) in AGC as Table 2.2 shows.
