Keysight N4432D RF Electronic Calibration Module

Overview

The Keysight N4432D is a precision 4-port RF electronic calibration (ECal) module designed to simplify and accelerate the calibration of Keysight vector network analyzers. ECal eliminates the need for traditional mechanical calibration kits, reducing the time required for full 4-port calibration by more than half while maintaining high accuracy. The module supports flexible connector configurations, mixing Type-N and 3.5 mm connectors in both male and female options up to 18 GHz.

The N4432D connects to vector network analyzers via USB for direct firmware control, minimizing operator interaction and the associated risk of errors. This approach also reduces wear and tear on test port connectors, lowering long-term maintenance costs.
