The HP/Agilent 8722ET is a 40 GHz S-parameter Vector Network Analyzer that delivers precise RF and microwave component characterization across a wide frequency span. Engineered for design validation, development, and production testing in telecommunications, aerospace, and radar applications, this instrument combines a synthesized source, test set, and tuned receiver into a single integrated platform. The 8722ET achieves up to 104 dB system transmission dynamic range and supports advanced calibration techniques including one-port, response, and enhanced response methods for source match correction.
