辐射发射(Radiated Emission)测试 电磁兼容的测试项目有很多,在电磁兼容试验中,每一个测试项目都是通过模拟电磁环境中的某一种干扰或抗干扰方式对产品所进行测试,以此评价产品干扰或抗干扰的影响程度,辐射发射(RE)测试是EMC的重要测试项之一。 一、定义 辐射是能量以电磁波形式由源发射到空间的现象。虽然我们看不到摸...
This paper reports on 15 currently available sets of measurement data from the ongoing CISPR/ radiated emission round robin test (RRT), carried out at open area test sites (OATS), or in semi-anechoic rooms (SAR). In the RRT, use is made of a very tightly specified EUT and measuring ...

A technique for the extrapolation of open-site radiated-emission test data to distances greater than the distance used during test is presented. Extrapolation factors are derived which are functions of frequency and polarization, but independent of the type of the source. With these factors, field ...
3.4 Layout and Radiated Emission Test Results of the LMR160X0 Figure 9 shows the top layer and mid-layer of LMR160X0 PCB layout. In this case, we make Input GND- HS switch-Diode-Output GND loop as small as possible, also add unbroken ground in the middle layer to improve the EMI ...
