The Agilent/Keysight 85036B is a mechanical calibration kit for vector network analyzers operating from DC to 3 GHz with Type-N connectors and 75-ohm impedance. It delivers the essential open, short, and load calibration standards required for accurate RF measurements across this frequency range.
Technical Specifications
• Frequency Range: DC to 3 GHz
• Impedance: 75 ohms
• Connector Type: Type-N
• Connector Torque Setting: 135 N-cm ±13.5 N-cm (12 in-lb ±1.2 in-lb)
– Key Features
The kit contains male and female open and short standards, a 75-ohm load termination, three Type-N to Type-N 75-ohm adapters, and one female open center-conductor extender. All opens and shorts are machined to precision tolerances. The short’s inner conductor features one-piece construction referenced to the shorting plane for repeatability. The female open uses a separate plastic inner conductor with low dielectric constant to minimize compensation requirements.
Adapters employ dual-beaded connector geometry for stable, repeatable connections built to tight tolerances. Pin depths are controlled to specification across all standards:
• Type-N Male Connectors: 0.207 to 0.210 inch
• Type-N Female Connectors: 0.204 to 0.207 inch
• Male Short Pin Depth: 0 to -0.0020 inches
• Female Short Pin Depth: 0 to -0.004 inches
• Type-N Adapters Pin Depth: 0 to -0.0030 inches
The kit withstands repeated use and handling without degradation of connection repeatability. Storage includes a foam-lined case with protective end caps.
– Typical Applications
Calibration of vector network analyzers and RF test equipment requiring accurate S-parameter measurements across the DC to 3 GHz band.
– Compatibility & Integration
Designed specifically for Agilent/Keysight network analyzers. Use open-end wrenches when disconnecting to prevent damage. Store with end caps and maintain clean mating plane surfaces. Performance verification requires return to Keysight Technologies for recertification using specialized equipment.
