Electronic Calibration Module, 300kHz to 20GHz, 3.5mm, 4-port

Manufacturer's part number :


Manufacturer Agilent Technologies

Keysight Technologies

Description :

The Keysight N4433A Microwave electronic calibration (ECal) module makes calibration of vector network analysers fast, easy, and accurate. ECal is a precision, single-connection calibration technique for your vector network analyser. 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 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 analyser and the software controls the rest.

ECal modules are transfer standards capable of transferring the factory calibration accuracy to your network analyser. The Keysight PNA and ENA series of network analysers controls the N4433A module directly through a USB interface. PNA Series network analysers require firmware revision 2.5 or higher.
