HP / Agilent 8719D 40GHz Microwave Vector Network Analyzer

The HP/Agilent 8719D is a high-performance vector network analyzer delivering precise S-parameter characterization across 50 MHz to 40 GHz. Built around a fully synthesized fast-sweeping source, integrated vector receiver, and solid-state S-parameter test set, this instrument measures magnitude, phase, group delay, insertion loss, and impedance with dynamic range up to 105 dB. The 1 Hz frequency resolution and 10 ppm accuracy support demanding RF and microwave component validation in telecommunications, aerospace, defense, and research environments.
