Agilent / Keysight 85052B Standard Mechanical Calibration Kit, DC to 26.5 GHz, 3.5 mm

The Keysight 85052B Standard Mechanical Calibration Kit is a precision instrument for characterizing and correcting systematic errors in network analyzers operating from DC to 26.5 GHz. Built around 3.5 mm connectors and 50 Ω impedance, this kit enables full two-port calibration and delivers traceable measurements across the entire frequency range.

Technical Specifications

• Frequency Range: DC to 26.5 GHz


• Connector Type: 3.5 mm (Precision Slotless Connectors, PSC-3.5)


• Impedance: 50 Ω


• Calibration Type: Full two-port


• Operating Temperature: +20 °C to +26 °C


• Storage Temperature: −40 °C to +75 °C


• Error-Corrected Range (Ambient Temperature Drift): ±1 °C

Key Features

• Metrology-grade calibration standards: offset opens, offset shorts, broadband loads, and sliding load terminations optimized to 26.5 GHz


• PSC-3.5 female connectors ensure stable impedance based solely on conductor geometry, independent of mating pin diameter variation


• Three 3.5 mm adapters (socket/socket, plug/socket, plug/plug) for non-insertable device measurement and connector preservation


• Complete gaging toolkit: 3.5 mm gage sets, centering bead, and 5/16 in torque wrench (90 N-cm / 8 in-lb) for connector verification and maintenance


• Includes commercial calibration certificate and documentation disk sets containing calibration definitions for 8510 and 872x systems

Typical Applications Network analyzer calibration and systematic error characterization across microwave and millimeter-wave frequencies. Suitable for S-parameter measurements, gain/phase tracking, and insertion loss verification where traceability and measurement repeatability are critical.

Compatibility & Integration Designed for Keysight network analyzer platforms including 8510 and 872x series systems. Kit documentation and data files support direct integration with these instruments.
