Agilent / Keysight 85033C 3.5mm calibration kit for 8752A, 8753

The Agilent/Keysight 85033C is a 3.5mm precision calibration kit engineered for accurate RF and microwave measurements on Agilent/Keysight network analyzers. It has a complete set of meticulously manufactured standards - open, short, load, and thru - designed to minimize systematic measurement errors and verify test setup performance. Each standard is precisely characterized across a wide RF and microwave spectrum to support high-fidelity calibration of both male and female connector configurations.

The kit reduces directivity, tracking, and reflection tracking errors, achieve measurement accuracy essential for RF circuit characterization, component verification, and system integration.

Technical Specifications

• Open Standards: Precision-characterized open circuit standards for male and female 3.5mm connectors; de-embeds fixture effects and defines reference planes


• Short Standards: High-quality short circuit standards for male and female 3.5mm connectors; critical for low-impedance measurement accuracy


• Load Standards: 50-ohm matched loads for characterizing measurement system response under terminated conditions


• Thru Standard: Low-loss, impedance-matched thru for transmission calibration Connector Interface


• Type: 3.5mm (SMA variant)


• Gender Configuration: Male and female standards included for multi-port calibration flexibility


• Impedance: 50 ohms nominal


• Precision: High-tolerance manufacturing to minimize connector repeatability errors and ensure accurate phase and amplitude response Frequency Range Operational frequency extends across the RF and microwave spectrum, determined by the paired network analyzer's capabilities.
