The Anritsu 3654D is a 1.85 mm (V-connector) calibration kit designed to deliver precise calibration for Vector Network Analyzers and high-frequency test instruments operating in microwave and millimeter-wave bands. This kit provides a complete set of calibration standards—opens, shorts, loads, and through connections—engineered to characterize and remove systematic errors from VNA measurements. The precision-manufactured standards ensure accurate reference-plane correction and impedance definition across the operational frequency range.
