The Keysight (Agilent/HP) 5361B is a high-performance 40 GHz Pulse/CW Microwave Counter designed for precise characterization of radar, electronic warfare (EW), and communication signals. It combines high-speed pulse measurement with CW counting capabilities, offering advanced features like frequency profiling to capture transients, chirp modulation, and linearity without needing a separate pulse generator or computer.
