The Keysight Technologies N4693D is a high-performance, 2-port Microwave Electronic Calibration (ECal) Module. Operating over a frequency range of 10 MHz to 50 GHz, it features precision 2.4 mm connectors. This ECal module simplifies vector network analyzer (VNA) calibration by replacing traditional manual calibration kits with an automated, highly repeatable, and NIST-traceable single-connection process, reducing operator error and port wear.
