Agilent/Keysight 85043C

The Agilent/Keysight 85043C is a precision electronic calibration (ECal) module that delivers fast, accurate network analyzer calibration through solid-state switching and direct software control. It functions as a transfer standard, propagating factory calibration accuracy to the network analyzer while eliminating operator errors inherent in traditional mechanical methods.

Technical Specifications

• Calibration Type: Fast, full two-port calibration with single connection; supports simple non-insertable device calibration


• Accuracy: NIST-traceable electronic impedance standards; module S-parameter data stored in onboard memory for error-term calculation


• Interface: USB connection for direct control with PNA and ENA series network analyzers


• Connectors: Mixed configurations available including 3.5 mm (precision slotless), Type-N 50 ohm, and 7-16 connectors in male or female options

Key Features

• Solid-state switching ensures reliability and long operational life


• Reduced connector wear versus mechanical calibration kits


• Minimal operator interaction required during calibration procedures


• Unique module characterization enables consistent, verifiable calibrations


• Electronic impedance standards eliminate connector insertion variability

Typical Applications

• Research and development environments requiring frequent calibration
