The Keysight N4433A is a 4-port Electronic Calibration (ECal) module operating from 300 kHz to 20 GHz. Designed for fast, highly accurate, and repeatable calibrations of vector network analyzers (VNAs), it features 3.5 mm RF connectors and is controlled directly via a USB connection, minimizing the risk of operator error and connector wear compared to manual calibration kits.
