Abstract

A system includes a communication apparatus coupled to a test subsystem through a converter. The test subsystem may be configured to initiate an audio test of the communication apparatus and receive in response a set of audio test data at a predetermined constant data rate. The communication apparatus may be configured to enable output of audio test data during inactive periods of operation of an RF circuit of the communication apparatus and to disable output of audio test data during active periods of operation of the RF circuit. The converter may be configured to receive the set of audio test data from the communication apparatus and provide the set of audio test data to the test subsystem at the predetermined constant data rate during the active and the inactive periods of operation of the RF circuit.
