This document details the procedure for measuring the Shielding Effectiveness (S.E.) of coaxial cable and connectors using the Gigahertz Transverse ElectroMagnetic (GTEM) cell. More particularly, this procedure applies to measuring the S.E. of 75 Ohm braided coaxial drop cables and connectors presently used within the broadband communications industry. S.E. measurements can be performed with or without the affixing coaxial connectors removed from the measurement. 1.3. Benefits This procedure exists in order to provide a standard method of testing between laboratories performing Shielding Effectiveness tests. When utilized this procedure helps to ensure confidence in results when published. 1.4. Areas for Further Investigation or to be Added in Future Versions Future revisions of this document may build upon the work started here by increasing the understanding of: • Variability of data between GTEM Cell systems with varied “uniform field” sizes. • The affects of location differences between bare wire and shielded samples within the GTEM cell. 2. Normative References The following documents contain provisions, which, through reference in this text, constitute provisions of this document. At the time of Subcommittee approval, the editions indicated were valid. All documents are subject to revision; and while parties to any agreement based on this document are encouraged to investigate the possibility of applying the most recent editions of the documents listed below, they are reminded that newer editions of those documents might not be compatible with the referenced version.
