摘要

测试点之间的校正系数通常基于调谐后的1/2 /spl λ /偶极子的天线方向图。实际设备显示出不同的天线方向图，在不同测试地点获得的结果之间的相关性失效。本文使用开放区域试验场，半消声室，全消声室和混响固有混响室进行20 MHz和1 GHz之间的发射测量。可以观察到超过40 dB的位点之间的差异。

Radiated electromagnetic fields of actual devices measured in different test environments

Correction factors between test sites are conventionally based on the antenna pattern of a tuned 1/2 /spl lambda/ dipole. Actual devices show diverse antenna patterns and correlation between results obtained at different test sites fails. This is shown in this paper using an Open Area Test Site, a Semi-Anechoic Chamber, a Full Anechoic Chamber and a Reverberating Intrinsic Reverberation Chamber for emission measurements between 20 MHz and 1 GHz. Differences between the sites of more than 40 dB can be observed.
