Agilent/Keysight 85563A

The Agilent/Keysight 85563A is a precision 3-in-1 OSL mechanical calibration kit engineered to calibrate Keysight network analyzers operating up to 50 GHz. Built around 2.4 mm female connectors with precision slotless connector (PSC) interfaces, this kit delivers the stable, repeatable connections essential for accurate high-frequency characterization. The kit includes three standards: offset open, offset short with one-piece inner conductor construction, and broadband 50 Ω termination—all with female 2.4 mm connectors. Load return loss ranges from 26 to 42 dB across the frequency band. Individual components are serialized to ensure traceability and measurement integrity. The compact, lightweight design prioritizes field portability without compromising calibration accuracy or connector reliability.
