Agilent/Keysight 8719ES

The Agilent/Keysight 8719ES is a two-channel vector network analyzer operating from 50 MHz to 13.5 GHz, designed for S-parameter characterization and RF/microwave component testing. It integrates a synthesized source, tuned receiver, and transmission/reflection test set to measure S-parameters, insertion loss, group delay, and impedance with dynamic range up to 115 dB and frequency accuracy of 10 ppm.
