Agilent HP Keysight 85093C RF Electronic Calibration Module (ECal), 300 kHz to 9 GHz, 3.5 mm, 2 Port

The Agilent HP Keysight 85093C is a two-port RF electronic calibration module (ECal) that enables fast, accurate vector network analyzer calibrations across 300 kHz to 9 GHz. Operating through a single 3.5 mm connection, it delivers full two-port calibration in a single connection, eliminating the complexity and setup time associated with traditional mechanical calibration kits. The module functions as a NIST-traceable transfer standard, conveying factory calibration accuracy directly to compatible network analyzers via USB control.

Solid-state switching and fully traceable electronic impedance standards ensure repeatability better than 0.02 dB while reducing operator interaction and connector wear.
