This paper presents the application of a measurement procedure for improving data acquisition for the characterization of soft magnetic ferrites. The approach is based on a voltamperometric technique and is aimed at better measure minor asymmetric cycles improving the quality and resolution of measurement data. Physical and mathematical conditions require the use of current and voltage signals with very different dynamic range since the major loop has to be traced together to the minor cycles. In such a way, the possibility to get the signal via two channels with different configuration is analyzed and discussed. Preliminary results are reported in the paper together to some preliminary concerns relevant to the metrological characterization of the method.

Abstract
This paper presents the application of a measurement procedure for improving data acquisition for the characterization of soft magnetic ferrites. The approach is based on a voltamperometric technique and is aimed at better measure minor asymmetric cycles improving the quality and resolution of measurement data. Physical and mathematical conditions require the use of current and voltage signals with very different dynamic range since the major loop has to be traced together to the minor cycles. In such a way, the possibility to get the signal via two channels with different configuration is analyzed and discussed. Preliminary results are reported in the paper together to some preliminary concerns relevant to the metrological characterization of the method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
