Agilent / Keysight N5224B 43.5 GHz PNA Microwave Network Analyzer

The Keysight N5224B is a 43.5 GHz PNA Microwave Network Analyzer engineered for characterization of microwave components and active devices including amplifiers, mixers, and frequency converters. The instrument integrates internal signal sources, receivers, pulse modulators, and flexible switching to enable both linear and nonlinear measurements on a single DUT connection.
