The Keysight (formerly Agilent / HP) 8719C is a high-performance vector network analyzer designed to characterize RF and microwave components from 50 MHz to 13.5 GHz. It integrates a fast-sweeping synthesized source, an S-parameter test set, and a tuned receiver into a single compact package, making it highly suitable for R&D, manufacturing, and quality assurance.
