Behavior of multifilar connectors in electromagnetic compatibility: a new experimental transient approach

A new experimental transient approach is proposed for multifilar connector characterization and more particularly for the scattering parameters evaluation and the maximum electrical field radiation estimation. This paper describes the analysis principle used to calculate the scattering parameters (S/sub ij/) of the connector, and the method proposed for electrical field magnitude estimation. Thereafter, the experimental setup and the calibration procedure for the multifilar measurement is explained. Finally, measurements using a vector network analyzer show the efficiency of the transient test setup.
