| Abstract(in English) | The radiated emission levels at a distance of 10 m are prescribed by the specification. Preliminary test for noise reduction is often performed at a distance of 3 m. The prediction method of the conformity test results from the preliminary ones, to which the finding method of radiated emission source is applied, has been already proposed. However that method has never been applied for a compact anechoic chamber of which antenna sweep range is limited. In this paper, we investigate the relationship between the prediction accuracy and the antenna sweep range. The relationship is verified by computer simulation and measurement with actual equipments. As a result, the prediction error is within 4 dB when the antenna maximum height is more than 3 m. In the case that the antenna sweep range is from 1 m to 2 m, the prediction accuracy is better than the 1/r prediction method. |
