Agilent/Keysight 8713B

The Agilent/Keysight 8713B is an RF network analyzer that characterizes and tests RF and microwave components from 300 kHz to 3 GHz. It combines a synthesized source, transmission/reflection test set, and dual-channel receivers in a single instrument, enabling swept frequency analysis with one connection. The analyzer delivers 100 dB system dynamic range and 50 ms sweep speed, making it suitable for high-volume manufacturing and laboratory environments requiring fast, accurate S-parameter and transmission/reflection measurements.
