Burst Audio Path Gain Calibration
Description
This test adjusts the scaling of the linear burst audio path until a -0.99 Vdc input to the
EXT1 connector results in a 40 dB drop in power relative to 0.00 Vdc input when linear
burst is activated. The AM 1 DAC value is changed until this result is achieved and its
value is stored as a calibration array.
