The Keysight N5245B is a high-performance 50 GHz microwave vector network analyzer (VNA) belonging to the flagship PNA-X series. Designed as a highly integrated microwave test engine, it replaces multiple racks of equipment by combining a VNA, spectrum analyzer, noise figure analyzer, and more into a single instrument. It is widely used for advanced active device characterization, including amplifiers, mixers, and frequency converters.
