Work is presented showing the usefulness of the parallel plate method to evaluate connector cable assemblies across a broadband range of 100 KHz to 40 GHz. The desktop method offers the advantage to separate connector emissions apart from cable emissions for a given sample. The automated measurement setup is explained in detail with test results presented for a few products. In principle, the parallel-transmission-line-plate [PTLP] method is a three- conductor problem. Simulation is required to determine the makeup of the principle mode of propagation traveling between the circular symmetric plates to better understand interaction with test sample. Field plots and correlation to measurement will be presented.
