The paper presents a method for the modelling of current probes, used in injection applications, up to 1 GHz. It is based on the determination of the S matrix of the probe thought as a three port network. The probe parameters are recovered by some measurements when it clamps a standard line, whose characteristics are theoretically known. The results pertaining the signal injected on a line using this model are compared with measurements and with the results obtained by a simplified probe model, based on a series transformer.

Abstract
The paper presents a method for the modelling of current probes, used in injection applications, up to 1 GHz. It is based on the determination of the S matrix of the probe thought as a three port network. The probe parameters are recovered by some measurements when it clamps a standard line, whose characteristics are theoretically known. The results pertaining the signal injected on a line using this model are compared with measurements and with the results obtained by a simplified probe model, based on a series transformer.File in questo prodotto:
