The Keysight (Agilent) 85059A is a precision 1.0 mm calibration and verification kit engineered for vector network analyzer systems operating across DC to 110 GHz. This kit delivers the calibration standards and verification components required to establish accurate, traceable measurements in RF and microwave test setups. The 85059A enables two distinct calibration methodologies: Open-Short-Load-Thru (OSLT) calibration from 45 MHz to 50 GHz, and offset-shorts calibration extending to 110 GHz, ensuring optimal VNA performance across the full frequency span.
