Abstract
Coded test signals in two or more distinct coding formats are applied sequentially to the equipment under test (EUT) according to a test sequence. The ordering, timing and source characteristics of the coded test signals are fully programmable. The output of the EUT is analyzed to verify proper decoding and detect audible artifacts. A means for comparing recorded test events allows a test engineer to detect failure modes of the autodetection system in the EUT.
