Today at the Department of Engineering of the University of Perugia, prof. Luigi Ferrigno from Cassino University reported the results of the in-anechoic chamber measurments performed on the first prototype of the magnetic positioning system. He presented the frequency response of receiving coils considering a passband relative to the -3 dB half signal amplitude points. He also showed the results of conducted immunity tests performed with a CDN (coupling decoupling networks) coupling a multisine disturbance to the system. The CDN was used to inject the disturbance toward the receiving coils or toward the data acquisition system. These results will be useful in order to design a new prototype more accurate and more robust with respect to EM disturbances.
