This paper investigates a signal acquisition protocol based on level-crossings that permits the demodulation of AM analog/RF signals using only standard digital ATE. The fundamental concept is to capture the signal through the 1-bit comparator available in digital tester channels and to process the resulting bit stream to retrieve the analog/RF signal characteristics. The proposed solution is evaluated through both simulation and hardware experiments.
