The Agilent/Keysight 85050D is an economy mechanical calibration kit for 7 mm interfaces operating from DC to 18 GHz. It delivers the precision standards required for 1-port and 2-port calibrations, including Thru-Reflect-Match (TRM) procedures on network analyzers. The kit corrects directivity, source matching, and reflection tracking errors to enhance measurement accuracy across RF and microwave applications.

– Key Features
The kit contains three precision calibration standards: an open circuit with low-dielectric collet depressor flush to the outer conductor, a short circuit with one-piece collet-based shorting plane for repeatable connections, and a metrology-grade broadband load with distributed resistive element on sapphire optimized to 18 GHz. A torque wrench calibrated to 135 N-cm (12 in-lb) ensures proper connections critical for measurement integrity. Gender-change adapters and standard definitions on disk for the 8510C network analyzer are included.
– Compatibility & Integration
Designed for calibration of Keysight 8720 series and 8510C network analyzers equipped with 7 mm interfaces.
