The Keysight Technologies 85052C is a precision 3.5 mm vector network analyzer (VNA) calibration kit operating from DC to 26.5 GHz. Designed primarily for TRL (Thru-Reflect-Line) and LRL calibration, the kit contains precision 50-ohm airlines, offset opens, offset shorts, broadband loads, precision adapters, and torque tools. It enables highly accurate 2-port calibration of compatible VNAs to ensure measurement traceability.
