| Abstract(in English) | Establishment of the methods of the EMI measurement for industrial, scientific and medical (ISM) radio firequency equipment dates back to the times in which the radio receivers only were in use. Therefore the methods have gone unatched to the present art of technique where the compatibility therein of the information technology equipment (ITE) is essential. To improve such situation, CISPR 11 (3rd version/1997) has recommended the method of measurement in common with ITE. Nevertheless the situation of producing considerably large error when changing the ISM mounting height, measuring distance, polarization has not yet been improved. This paper describes that the basic cause stems on the "undefined measure" inherent in the current measurement system and proposes how to improve this through making free space the test site. |
