PT4 Failure Description
You can determine failure results ($>0) by the individual bit settings:
BIT # PT4 Failure Description
0 ADC Timeout Error - The Timing Generator ADC was not ready for reading
when the CPU was ready to read the ADC.
1 Transmit Timeout - The Timing Generator never indicated completion of
transmission.
2 Sample Timeout - The Timing Generator never indicated completion of
sampling.
3 LCA Registers Corrupted - The contents of the Timing Generator’s
registers is corrupted.
4 Overcurrent Shutdown.
5 Overtemperture Shutdown. Not applicable to the ADFM
6 Incorrect Transducer Impedance. Could be caused by a short or an open
connection in the transmit circuit, including the transducer.
7 Low Transmit Voltage And/Or Current. The transmit voltage and/or the
transmit current was to low.
PT5 - Electronics Wrap Around
Purpose: This tests runs a through test on the ADFM electronic circuits.
Format: PT5
Description: This test sets up the ADFM in a test configuration in which
the test output lines from the Triple Board timing generator
are routed directly to the demodulators. The demodulators
then process this signal. Test failures indicate possible prob-
lems with the Receiver, Demodulator, or Timing Generator.
