Analog IF Input Detector Adjustment
The adjustment determines the power detected by the A8 Analog IF (AIF) input power
detector under known conditions. The detector gives a DC level which corresponds to this
power. An ADC converts this DC level to a digital value which is then stored in the A8
EEPROM.
The 321.4 MHz calibrator on the A10 Third Converter is used to provide a stable -7 dBm,
21.4 MHz signal to the A8 input. A power meter is used to measure this signal at A10J5 to
accurately set its power level.
This adjustment should be performed after replacing the A8 assembly.
