The Keysight 85091C RF electronic calibration (ECal) module makes 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 number of connections using ECal versus mechanical cal 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.

ECal modules are transfer standards capable of transferring the factory calibration accuracy to your network analyzer. The new 85091C RF electronic calibration system is now easily controlled by one of two methods depending on the network analyzer. The Keysight PNA and ENA series of network analyzers controls the module directly through a USB interface.
