Differential Transfer Impedance of Shielded Twisted Pairs
Michel Mardiguian, EMC Consultant, Saint-Rémy-lès-Chevreuse, France The concept of Shield Transfer Impedance (Zt), introduced by S. Schelkunoff in 1934, is a very convenient parameter for the prediction and control of EMI coupling through cable shields. Although widely applied to coaxial cables against EMI susceptibility problems, the Zt parameter can be easily extended to … [Read more...]
Effective EMC Troubleshooting with Handheld Probes
EMC testing is an unavoidable part of the development cycle for electronic products. As clock frequencies continue to increase, radiated emissions get harder to control. In an ideal world, the R&D engineer would test the emissions from his product early in the design stage and retest frequently as design changes were made, just ass he tests whether his product meets its … [Read more...]
