Abstract :
An inexpensive, simple, and sensitive workbench setup has been developed to determine the transfer impedance Zt of shielded connectors. The injection current is measured by an inductive sensor integrated in the setup. The induced voltage is determined by a spectrum/network analyzer. The overall sensitivity is 3 μΩ or better; the frequency range is up to 1 GHz. No special calibration samples are needed. As a demonstration the Zt is measured for both a coaxial tube with a small hole in the shield which provides a mutual inductance of 0.1 pH. Improvements in the design of the shield of a telecommunication connector are presented. Results for some common connectors are given; the transfer impedances for these connectors ranges from 1 mΩ to more than 100 mΩ at 1 GHz
