The Keysight (Agilent) 8719A is a high-performance network analyzer for RF and microwave device characterization across 130 MHz to 13.5 GHz. Built on a fully synthesized source architecture with switching S-parameter test set capabilities, it delivers fast measurement updates and high dynamic range in a compact, production-ready platform. The instrument excels at component validation—filters, amplifiers, antennas, and transmission line structures—and serves manufacturing, incoming inspection, and final test workflows with equal effectiveness.
Technical Specifications
