Description:
The Agilent N4431B 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 three- or four-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 Agilent PNA and ENA series of network analyzers controls the N4431B module directly through a USB interface. PNA Series network analyzers require firmware revision 2.5. Note: The 9 kHz to 300 kHz performance is only applicable to the E5071C with firmware revision A.09.10 or higher.
