The Keysight 85031B is a precision 7 mm calibration kit designed for vector network analyzers (VNAs) operating in the DC to 6 GHz frequency range. This kit features high-performance APC-7 genderless connectors and is primarily used to perform full one-port or two-port calibrations (SOLT method) to minimize systematic measurement errors.
