A16J3, a 321.4 MHz, - 25 dBm
signal can be injected directly into the input of Third Converter Assembly
A10 at blue cable
A1OW1. Set signal generator COUNTER MODE to EXPAND
XI00 (most significant digit will overflow).
3. Adjust signal generator frequency until spectrum analyzer trace is at peak. Put signal generator OUTPUT
LEVEL to position trace at top graticule line.
4. Tune signal generator until trace drops to
2 divisions above graticule baseline. Record signal generator
