半电波暗室归一化场地衰减测试探讨
Discussion on Calculation and Measurement of Normalized Site Attenuation of Semi-Anechoic Chamber
摘要
Abstract
Basic principles and common methods of NSA (Normalized Site Attenuation) test for the performance of the semi-anechoic chamber were introduced ifrst in this paper. The theoretical value of NSA tests under the conditions of 3 m and 10 m range semi-anechoic chamber were calculated and the general test procedures of EMC (Electromagnetic Compatibility) NSA were analyzed. Then, the semi-anechoic chamber was tested preliminarily and the actual measurement data was achieved. Finally, the general factors affecting the test results were discussed. And the evaluation results showed that the chamber could work normally.关键词
