The Agilent/Keysight 85033D is a 3.5 mm mechanical calibration kit for precise network analyzer calibration across DC to 6 GHz. It delivers metrology-grade performance through offset opens, offset shorts, broadband load terminations, and dual-beaded adapters—each engineered to minimize phase error and maximize connection repeatability.
Technical Specifications
• Model: 85033D
• Manufacturer: Agilent / Keysight
• Connector Type: 3.5 mm (male and female)
• Impedance: 50 ohms

– Key Features
• Broadband Load Terminations: Distributed resistive element on sapphire substrate ensures stability and return loss performance to 6 GHz.
• Offset Opens: Low-dielectric-constant plastic support with tightly controlled pin depth minimizes phase errors and compensation requirements.
• Offset Shorts: One-piece inner conductor design with integrated shorting plane delivers extremely repeatable connections and controlled phase response.
• Dual-Beaded Adapters: Connector architecture optimizes stability and minimizes return loss; nominal electrical lengths matched for non-insertable device calibration.
• OSL Holders: Two storage and measurement assemblies enable single-load calibration cycles for same-sex connectors.
• Calibration Definitions Disk: Nominal device definitions load directly into compatible network analyzers.
• 2.5 mm Hex Key: Included for secure fastening of calibration devices within holders.
– Typical Applications
Precision characterization of RF and microwave components with 3.5 mm connectors. Network analyzer system calibration. High-accuracy S-parameter and transmission measurements across broadband frequency spans.
– Compatibility & Integration
Designed for systems requiring 50 ohm calibration standards. Component pairing (male and female) supports both device port configurations. Calibration definitions are compatible with network analyzers accepting standard definition formats.
