HP / Agilent 8712B RF Network Analyzer

The HP/Agilent 8712B is a single-unit RF network analyzer combining synthesized source, transmission/reflection test set, and dual-mode receivers for production-grade S-parameter and impedance characterization. Operating from 300 kHz to 1.3 GHz, it delivers fast measurements with >100 dB narrowband dynamic range, automated calibration correction, and integrated data storage. Purpose-built for manufacturing test, incoming inspection, and field maintenance of RF components and systems.
