Keysight Technologies Inc. ECal module 18 GHz 4-port
The Keysight N4432D is a 4-port Electronic Calibration (ECal) module designed for use with Keysight vector network analyzers. Operating up to 18 GHz, it enables fast, repeatable, and highly accurate calibration of multiport test setups. The N4432D automates the calibration process, reducing operator errors and setup time compared to manual calibration kits. It is USB-controlled and compatible with a wide range of Keysight network analyzers, supporting both coaxial and mixed-mode S-parameter measurements. The module is ideal for R&D and manufacturing environments requiring efficient, high-performance multiport calibration.
