Agilent/Keysight 8712B

The Agilent/Keysight 8712B is an RF network analyzer that integrates a synthesized source, test set, and dual-channel display for vector measurement of RF components and networks across 300 kHz to 1.3 GHz. Purpose-built for high-volume manufacturing environments, it delivers phase, complex impedance, and linear group delay measurements with two independent display channels capable of simultaneous dual-parameter visualization.
