摘　　要：不同标准对1 GHz以上辐射发射(RE)测量要求有所不同,尤其是对测试环境(即电波暗室)的要求或者设计,需考虑多项影响因素,特别是内部净空使用高度问题。基于多年的工程经验,总结了不同标准需要注意的地方,重点解读了接收天线在高度上是否需要连续升降扫描、方向上是否需要俯仰测量等问题,并给出了相应的应用分析。Different standards have different requirements for the measurement of radiated emission(RE)above 1 GHz,especially for the requirements or design of the test environment(i.e.anechoic chamber),many factors need to be considered,especially the internal clearance height.Based on many years of engineering experience,this paper summarizes the points that need to be paid attention to in different standards,focuses on whether the receiving antenna needs continuous up and down scanning in height,whether it needs pitch measurement in direction and so on,and gives the corresponding application analysis.
