The Agilent/Keysight 85519A is a 4-in-1 OSLT mechanical calibration kit that delivers open, short, load, and through standards for accurate VNA calibration across DC to 18 GHz. Built with Type-N female connectors and 50-ohm impedance, this kit enables precise compensation of systematic errors in RF and microwave test systems. Its compact form factor and lightweight design support field and laboratory deployment. The integrated through standard uniquely facilitates calibration of non-insertable devices—such as female-female connectors on cables and filters—without requiring adapter configurations.
