Agilent / Keysight N5235B 50 GHz PNA-L Microwave Network Analyzer

The Keysight N5235B is a 50 GHz PNA-L microwave network analyzer engineered for RF and microwave component characterization. It delivers precision S-parameter measurements from 10 MHz to 50 GHz with 122 dB dynamic range and 0.003 dB RMS trace noise. The dual-port architecture with single synthesized source, 6 dBm output power, and 6 ms best sweep time (201 points) supports rapid production testing and lab measurements without sacrificing measurement fidelity.
