PT3 Failure Description:
Low Correlation – Correlation at lag 1 is <70% (130 counts) for beams
4,3,2,1.
High Correlation - A correlation at lag 11 or above is >63 counts for
beams 4,3,2,1
High Noise Floor – Noise floor for high gain is >59 for beams 4,3,2,1.
Low Differential Gain - not applicable to the ADFM
This test displays transmit path characteristics.
PT4
During the test, the ADFM pings and measures the resulting
transmit current and voltage.
