Agilent / Keysight 85056A Standard Mechanical Calibration Kit, DC to 50 GHz, 2.4 mm

The Keysight/Agilent 85056A is a standard mechanical calibration kit engineered for precision two-port VNA calibration across DC to 50 GHz using 2.4 mm connectors. This kit delivers the calibration standards, adapters, gaging tools, and accessories required to characterize and correct systematic errors in RF and microwave test systems, enabling high-accuracy network analyzer measurements.

Technical Specifications

Frequency Range: DC to 50 GHz
Connector Type: 2.4 mm
Dimensions: 15 × 12 × 9 inches
Weight: 4 lbs Calibration standards include offset opens (male and female), offset shorts (male and female), broadband loads (male and female), and sliding loads (male and female). Three 2.4 mm adapters support connector sex conversion: female-female, male-male, and male-female configurations.

Key Features Connector Gaging & Maintenance

• Male and female gage kits with included gage masters


• Centering bead for gaging 2.4 mm sliding loads


• Ensures connector integrity and dimensional compliance Calibration Tools


• 5/16 inch, 8 in-lb (90 N-cm) torque wrench for repeatable standard connections


• 7 mm open-end wrench Standards Construction

Broadband loads are metrology-grade 50 Ω terminations optimized to 50 GHz with rugged internal structure for repeatable connections, excellent stability, and controlled return loss. Offset opens and shorts feature precision-machined construction, one-piece inner conductor design for shorts, and low-dielectric-constant plastic support for opens to minimize phase errors and compensation requirements. Documentation Calibration definitions disks for Agilent 8510 and 872x platforms, PNA Series software support, user and service guide, and calibration definition data disks.

Typical Applications Full two-port VNA calibration for RF and microwave measurements requiring traceable, repeatable reference standards across the DC to 50 GHz band.

Compatibility & Integration Designed for Keysight and Agilent vector network analyzers supporting 2.4 mm interfaces for measurements to 50 GHz.
