PT3 Failure Description
You can determine failure results ($>0) by the individual bit settings:
BIT # PT3 Failure Description:
0,4,8,12 Low Correlation – Correlation at lag 1 is <70% (130 counts) for beams
4,3,2,1.
1,5,9,13 High Correlation - A correlation at lag 11 or above is >63 counts for
beams 4,3,2,1
2,6,10,14 High Noise Floor – Noise floor for high gain is >59 for beams 4,3,2,1.
3,7,11,15 Low Differential Gain - not applicable to the ADFM
PT4 - Transmit Path
Purpose: This test displays transmit path characteristics.
Format: PT4
Description: During the test, the ADFM pings and measures the resulting
transmit current and voltage.
For example:
>pt4
----------- BEAM 1 -----------
IXMT = 44.5 Ml Amps peak
VXMT = 5.4 Volts peak
RXMT = 120.4 Ohms
Transmit Test Results = $0 ... PASS
----------- BEAM 2 -----------
IXMT = 40.2 Ml Amps peak
VXMT = 5.5 Volts peak
RXMT = 135.8 Ohms
