Correlation between Shielding Effectiveness and Transfer Impedance of Shielded Cable

摘要

The correlation between the shielding effectiveness and transfer impedance of a 50Ω shielded cables was evaluated. The methods used in the performance of the investigation to induce the currents and voltages into the wires and cables were by use of an electric dipole antenna and a current probe. A direct correlation between shielding effectiveness and transfer impedance was recorded on a BNC cable that was terminated in 50Ω at both ends.
