Interpreting Results
When a failure occurs, a message is displayed showing the number of failures and the
probabilitythat the failure is caused by the assembly being tested. If the probability is not
high, more measurements may be necessary to verify the failure.
The probability assigned is based on the following criteria:
Low: A failure occurred, but the signal being used for the measurement originates in
another assembly and has not been previously tested on this assembly. Low probability is
also assigned for the first measurement made to an assembly.
Medium: A failure occurred and the signal being used for the measurement originates in
another assembly and has already been measured good, but the measurement mux
(multiplex) point or digital detector has not previously been used.
High: A failure occurred and the signal being used for the measurement originated in
another assembly and has already been measured good, and the measurement mux point
or digital detector has already been used.
The RF diagnostics assign probability based on the first failure that occurs. The audio
diagnostics assign probability based on a series of measurements.
