The Keysight Agilent 8720ET is a transmission/reflection (T/R) vector network analyzer designed for the cost-effective characterization of RF and microwave components from 50 MHz to 20 GHz. It integrates a synthesized source, a T/R test set, and a tuned receiver in a single compact unit, providing magnitude and phase measurements in the forward direction alongside comprehensive vector accuracy enhancements.
