Abstract
The method of the current probe is used to recover the transfer parameters of coaxial cables. The measurements are carried out by means of only one current probe and using scalar instrumentation, resulting in a very simple and cheap setup compared with other techniques. This paper presents the relative theory showing that the assumption of weak coupling can be adopted; the results obtained for a typical cable are compared with that obtained by the triaxial technique and the line-injection method; a comparison is also performed with theoretical data obtained for the transfer impedance by several modelsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
