Keysight Technologies Inc. ECal module 26.5 GHz 4-port 3.5 mm
The Keysight N4433D is a 4-port electronic calibration (ECal) module designed for vector network analyzers (VNAs) and operates up to 26.5 GHz with 3.5 mm connectors. This module automates the calibration process, reducing the time and complexity associated with manual calibration methods. It provides repeatable, accurate calibrations for multiport measurements, supporting both full two-port and multiport calibration techniques. The N4433D is USB-controlled, allowing for direct connection to compatible Keysight VNAs, and is ideal for applications requiring high measurement accuracy and efficiency in R&D and manufacturing environments.
