Agilent / Keysight N5247B 10 MHz to 67 GHz PNA-X Microwave Network Analyzer

The Keysight N5247B PNA-X is a 10 MHz to 67 GHz microwave network analyzer engineered for R&D characterization of RF, 5G, and radar components. This integrated platform consolidates S-parameter, noise figure, and intermodulation distortion measurements into a single instrument, eliminating the need for multiple test systems. The analyzer delivers system dynamic range up to 129 dB with trace noise as low as 0.002 dB RMS, enabling high-accuracy linear and nonlinear measurements across passive and active devices.
