ANSI SCTE 48-3:2018 pdf download.Test Procedure for Measuring Shielding Effectiveness of Coaxial Cable and Connectors Using the GTEM Cell.
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 he 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.
