AM Gain Calibration
Description
This test adjusts the gain of the AM circuitry to provide a 10 dB drop for a 1 V input signal.
First a power level is set and a one-volt signal is connected to the input. AM is enabled and
the AM DACs are adjusted for an exact 10 dB drop. The resulting DAC value is stored as a
calibration array.
