Keysight N4433D RF Electronic Calibration Module

Overview

The Keysight N4433D is a precision 4-port RF electronic calibration module extending to 26.5 GHz, designed for high-frequency vector network analyzer calibration. With optional DC extension (Option 0DC), the module covers the full range from DC to 26.5 GHz, making it ideal for broadband device modeling and time-domain signal integrity analysis. The N4433D supports flexible 3.5 mm connector configurations, allowing selection of male and female connectors per port to match specific test setups.

This ECal module provides full 4-port calibration in less than half the time of traditional mechanical kits while maintaining high accuracy. The USB interface enables direct control from Keysight network analyzers, reducing operator interaction and minimizing the risk of errors. Connector wear is significantly reduced, lowering long-term maintenance costs.
