Keysight Technologies Inc. RF Ecal module, DC/300 kHz to 9 GHz, 7 mm
The Keysight 85091D is an RF Electronic Calibration (ECal) module designed for vector network analyzers, covering a frequency range from DC/300 kHz to 9 GHz with 7 mm connectors. This module enables fast, repeatable, and highly accurate one- or two-port calibrations for network analyzers, significantly reducing calibration time compared to traditional mechanical calibration kits. The 85091D is USB-controlled, allowing for direct connection to a PC or compatible network analyzer, and supports automated calibration routines. It is ideal for use in laboratory and production environments where efficiency and accuracy are critical. The module is compatible with a wide range of Keysight network analyzers and is designed to improve measurement consistency and reduce operator errors.
