Agilent N5245A 50 GHz PNA-X Microwave Network Analyzer

The Agilent N5245A is a 50 GHz PNA-X microwave network analyzer designed for precision characterization of RF and microwave devices across 10 MHz to 50 GHz. It consolidates multiple test instruments into a single platform, reducing measurement time and station complexity. The instrument delivers 126 dB system dynamic range and 129 dB receiver dynamic range, supporting both 2-port and 4-port configurations with dual internal sources.

Advanced measurement modes include S-parameters (CW and pulsed), noise figure, gain compression, intermodulation distortion, X-parameter characterization, and pulsed-RF analysis with narrowband detection that improves dynamic range by 40 dB for pulses narrower than 267 ns.
