The Keysight N5245BV is a specialized amplifier characterization system built on the N5245B PNA-X Microwave Network Analyzer. It integrates hardware, application software, and calibration tools to measure gain compression, intermodulation distortion, noise figure, error vector magnitude, noise power ratio, and adjacent channel power ratio using wideband modulated signals. The platform consolidates multiple measurement functions into a single test engine, reducing setup complexity and test time for R&D and manufacturing environments.
