RF Electronic Calibration Module (ECal), DC/300 KHz To 9 GHz, 4.3-10, 2 Port
85094D
Electronic Calibration Module
The Keysight 85094D RF electronic calibration (ECal) module makes the calibration of vector network analyzers fast, easy, and accurate. ECal is a precision, single-connection calibration technique for your vector network analyzer. Performing a full two-port calibration takes less than half the time and a number of connections using ECal versus mechanical calibration kits. Furthermore, the accuracy of the calibration is comparable between electronic and mechanical methods. Traditional mechanical calibrations require intensive operator interaction, which is prone to errors. With ECal, the operator simply connects the ECal module to the network analyzer and the software controls the rest.
