Agilent / Keysight 85050D Economy Mechanical Calibration Kit, DC to 18 GHz, 7 mm

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.
