Abstract

Recently, site evaluation of anechoic chamber for EMI over 1GHz has attracted much attention because EU and VCCI start the regulation for EMI above 1GHz from October 2010. In the international standard, CISPR16-1-4 [1], SVSWR method has defined as a site evaluation method for EMI anechoic chamber over 1 GHz. The SVSWR method is specialized for validating the anechoic chamber hence the relationship between SVSWR and the EMI results is not clear. Therefore, the quantitative evaluation of site performance is difficult by the SVSWR.
