Keysight N4693D Electronic Calibration Module (ECal), 50 GHz, 2.4 mm, 2-port

The Keysight N4693D is a 2-port electronic calibration module engineered for rapid, traceable calibration of vector network analyzers operating to 50 GHz. Equipped with 2.4 mm connectors, this ECal module eliminates manual calibration kit requirements by embedding precisely characterized internal standards. It emulates full 2-port SOLT calibration (Short, Open, Load, Thru), providing high accuracy and excellent repeatability while significantly reducing systematic VNA and test system errors. The module communicates with compatible VNAs via dedicated interface, automatically loading calibration data into the network analyzer for streamlined measurement workflows in RF and microwave environments.
