Measurements of transfer impedance with the line injection method on cables and connectors

In an electronic system the connection cables and the relevant connectors have been recognized as one of the main causes of interference in different apparatus. Different methods are used to evaluate the shielding effectiveness of cables and connectors. In this paper the method of the line injection is addressed and the results of measurements on a number of samples of cables and connectors are presented. The measurements on the same samples were carried out in two different laboratories in order to assure the reliability of the method.
