The Agilent/Keysight N4433AC43 is a 4-port electronic calibration module that transfers factory calibration accuracy directly to vector network analyzers. This ECal solution eliminates the complexity of mechanical calibration kits by using a single-connection technique, dramatically reducing setup time and connection count while maintaining measurement repeatability across DC to 12 GHz.
Operating as a transfer standard, the N4433AC43 stores unique S-parameter data in onboard memory. During calibration, the analyzer retrieves this data to calculate error terms automatically, minimizing operator interaction and connection-related measurement errors. USB control via compatible Keysight network analyzers streamlines the entire workflow, enabling faster test cycles and consistent results in R&D, manufacturing, and service environments.
