Abstract

This paper analyzed a potential interference of electric equipments on radio service below 30MHz through an experiment with a PDP(Plasma Display Panel) TV and a RF(Radio Frequency) light bulb in an anechoic chamber. The radiation levels of the PDP TV and the RF light bulb are measured and a combined interference is calculated on the basis of the experimental value. As a result, the combined interference signal level is increased according to the number of interferer. The possibility of a potential interference from electric equipments on radio service below 30MHz is realized through comparison between the measured radiation value of electric equipments and the CISPR(International Special Committee on Radio Interference) 11 limit.

본 논문은 대표적인 전파응용기기로 알려진 PDP(Plasma Display Panel) TV와 RF(Radio Frequency) 전구가 30MHz 이하 무선 서비스에 대한 전자기기의 잠재적 간섭 영향을 분석한 것이다. PDP TV와 RF 전구의 방사 크기를 전자파무반사실에서 측정하였고 이를 바탕으로 다수의 간섭 신호가 존재하는 경우에 결합된 간섭신호의 크기를 계산하였다. 분석 결과, 간섭원의 수에 따라 결합된 간섭 신호의 크기가 증가되는 경향을 확인하였다. 실험을 통해 얻어진 전자기기의 방사 측정값과 CISPR(International Special Committee on Radio Interference) 11의 제한치를 비교함으로 30MHz 이하의 무선 서비스에 대한 전자기기 간섭 잠재성을 확인하였다.
