A New Technique for Low-Cost Phase Noise Production Testing from 1-bit Signal Acquisition
Abstract
This paper introduces a new technique for low-cost phase noise production testing from 1-bit signal acquisition. The technique relies on reconstruction of phase fluctuation from the binary vector captured by a digital ATE channel. A dedicated post-processing algorithm is developed that permits phase noise evaluation from the analysis of the reconstructed time-domain phase fluctuation. The technique is validated through hardware measurements and results demonstrate an excellent agreement with conventional phase noise measurements.
