Abstract
A description is given of a 10-m open-area test site (OATS) for measuring radiated electromagnetic emissions from computing devices. The test site, located in southeastern Minnesota, is described. Its performance is analyzed by comparing horizontal and vertical site attenuation measured at the site to a theoretical model. The impact of the ground screen is examined by analyzing site attenuation data from two OATSs. The model developed by A.A. Smith et al. (1982) is used. The effects of the ground screen's size and the termination of its edges are discussed. Three methods of edge termination are examined. The vertical polarization is more sensitive to imperfections in the ground screen; hence, the bulk of the data presented is from vertically polarized site attenuation measurements.<>
介绍了一种用于测量计算设备辐射电磁发射的10米露天试验场(OATS)。该试验场位于明尼苏达州东南部。通过将现场测得的水平和垂直场地衰减与理论模型进行比较，分析了其性能。通过分析两个oats的现场衰减数据，考察了地面屏蔽的影响。采用a.a.s mith et al.(1982)开发的模型。讨论了地屏尺寸及其边缘终止的影响。研究了三种边缘终止的方法。垂直极化对地屏缺陷更敏感;因此，所提供的大部分数据来自垂直极化站点衰减测量。
