The Agilent/Keysight 83495A is a clock recovery module that extracts clock signals from high-speed optical and electrical data streams for digital communication systems. It performs clock recovery and data regeneration, enabling accurate timing measurements, synchronization, and signal integrity analysis. The module integrates with Agilent 86100-series and 83480A Digital Communications Analyzers to function as a multi-rate reference receiver and generate trigger signals for waveform characterization and compliance testing.
