Measuring the coupling parameters of shielded cables

Methods for measuring the coupling parameters of shielded cables, transfer impedance, and transfer admittance are presented. In addition to a theoretical analysis, a simple easy-to-use low-cost measuring setup is shown. This setup permits the determination of modulus and phase of the coupling parameters. New measuring methods for the direct determination of the so-called optimizing factors, presented in an earlier paper (see ibid., vol.34, no.2, p.39-46, 1992) are also discussed. These methods are suitable for shielded cables and shielded cable harnesses as well
