摘要: Calibrating automatic test equipment (ATE) includes adding jitter to a test signal to produce a jittered signal, sampling the jittered signal to produce digital values, generating a reconstructed jittered signal from the digital values, determining an amount of jitter in the reconstructed jittered signal, and calibrating the ATE based on the amount of jitter in the reconstructed jittered signal.
