The SP926N is all-in-one RF noise figure analyzer under Prosund SP900N series, continuous frequency coverage from 10MHz to 26.5GHz in compact 2U rack-mount chassis, integrating three core functions: Y-factor noise figure measurement, spectrum analysis and IQ vector demodulation analysis, replacing traditional separate noise analyzer + spectrum analyzer combo. Target applications include 5G Sub-6G RF frontends, WiFi/Bluetooth/IoT wireless modules, 24GHz automotive radar, satellite receivers, LNAs, mixers, filters, RF receive chains, mass production FCT noise indicator testing and university RF communication lab calibration for SME R&D.
