Using TEM waveguides according to the new IEC 61000-4-20

TEM waveguides are widely used for radiated emission and immunity testing of small EUTs. Several standards use product specific test setups with TEM waveguides. To support these TEM waveguide applications, IEC has now published the international basic standard IEC 61000-4-20 on EMC testing and measurement techniques using TEM waveguides. This article summarizes the standard, describes the validation procedure of a GTEM cell and the emission testing of a small EUT
