Microwave electronic calibration (ECal) module

The Agilent N4433A Microwave 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 three- or four-port calibration takes less than half the time and a number of connections using ECal versus mechanical cal kits. Furthermore, the accuracy of the calibration is comparable to 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.Features：300kHz to 20GHz frequency rangeStandard 3.5mm (f) connectorsFast full 3- or 4-port calibration with a single connectionNIST traceable accurate calibrationsReduced connector wearUSB interface for direct control with PNA and ENA series of network analyzersReliable solid-state switching
