TEST DEVICE FOR TESTING DISC PLAYER

摘要

A test device is used for testing a disc player, the disc player includes a power terminal and an audio output terminal The power terminal outputs a supply voltage when the disc player reads a disc. The test device includes a detecting unit connected to the power terminal and the audio output terminal, the detecting unit being powered by the supply voltage to detect whether the audio output terminal outputs a digital audio signal and generate a first level signal when the detecting unit detects that the audio output terminal outputs the digital audio signal; and a processing unit responding to the first level signal by determining that the audio output terminal of the disc player successfully outputs the digital audio signal.
