The Keysight 83496A Clock Recovery Module extracts clock signals from high-speed NRZ data streams for waveform analysis, bit error rate testing, and jitter characterization. This plug-in module integrates with Keysight Digital Communications Analyzer (DCA) mainframes to deliver precision timing recovery across electrical and optical signal paths.
