This guide is aimed at users of GTEM cells. Its purpose is to help them achieve good practice in EMC emission and immunity tests with their GTEM cell. Reference is made to the IEC Standard 61000-4-20 on the EMC uses of GTEM cells.
York EMC Services Ltd and the National Physical Laboratory (NPL) undertook a project under the National Measurement System Policy Unit (NMSPU) policy to investigate the use of GTEM cells in EMC testing.
The aim of the project was to support UK industry by quantifying and reducing measurement uncertainties in the use of GTEM cells in EMC testing.
The project was divided into two parts:
The project findings are summarised in the Measurement Good Practice Guide Nº.65 “The use of GTEM cells for EMC Measurements” which can be downloaded below.
Hard copies can be purchased directly from the NPL’s online store.
This project was sponsored by the National Measurement System Policy Unit of the Department of Trade and Industry as part of the NMS Electrical Programme 2000-2003. The work was carried out by staff of the National Physical Laboratory and York EMC Services Ltd. Members of the UK GTEM Users’ Group provided input on the practical use of GTEM cells for EMC testing and EMC Hire Ltd. repeated the emission measurements in their GTEM cell.
