The N4431B RF electronic calibration (ECal) module lets you calibrate vector network analyzers quickly, easily and accurately. ECal is an accurate, single-connection calibration technique for your vector network analyzer. A complete three- or four-port calibration takes less than half the time and number of connections with ECal compared with mechanical calibration kits. In addition, calibration accuracy is comparable between electronic and mechanical methods. Traditional mechanical calibrations require intensive operator interaction, which is prone to error. With ECal, the operator simply connects the ECal module to the network analyzer and the software handles the rest.
ECal modules are transfer standards capable of transferring factory calibration accuracy to your network analyzer. PNA and ENA series network analyzers control the N4431B module directly through a USB interface. PNA series network analyzers require firmware revision 2.5.
