Testing silicon TV tuners on ATE without TV signal generator

摘要

Silicon TV tuners are rapidly displacing traditional CAN tuners. There are two main challenges in testing silicon TV tuners in production: the lack of TV signal generator on stand-along ATE and the long test time of traditional test methods. In this paper, we first present a method to create TV test signals on ATE so we can develop gold standard tests for two most challenging tests: infrequent glitch detection and ATV test. We then propose a scheme that removes the need of TV test signals while performing the tests >10 times faster.
