摘要
辐射发射(RE)的设计和远场测试整改复杂、成本高,为了解决中小规模公司缺乏低成本、简单的近场摸底测试系统的问题,设计验证了一种基于数字示波器的近场辐射发射测试系统,可用于获取远场RE102测试的频谱走向和趋势,使产品的EMI认证成本减少1/3,试验周期缩短1/5。为远场测试整改难度大、成本高的问题提供了一种解决方案。
The design and far-field test of radiated emission(RE)are complex and costly.In order to solve the problem that small and mediumsized companies lack low-cost and simple near field testing system.This paper designs and verifies a near field radiated emission test system based on digital oscilloscope,which can be used to obtain the spectrum trend and trend of far field RE102 test,so that the cost of products in the EMI certification process can be reduced by 1/3,and the test cycle can be shortened by 1/5.It provides a solution for the difficult and high cost problems of far-field test rectification.
