Agilent/Keysight 11500I

The Agilent/Keysight 11500I is an electronic calibration (ECal) module that automates VNA calibration through solid-state impedance standards, eliminating manual mechanical calibration steps. Designed for 3.5 mm connector interfaces, it delivers traceable, repeatable calibration with single-connection full one- to four-port capability, reducing operator error and test time across RF and microwave measurement workflows.
