"U盘电磁兼容性检测实践与总结：方法标准与流程分析，解决问题思路与整改方案"

This essay discusses the electromagnetic compatibility (EMC) testing of USB flash drives as an example, introducing the basic knowledge of EMC and focusing on the EMC testing methods for information technology products, as well as the testing items, related standards, and procedures for CE certification. Drawing on personal experience and hands-on operations at an EMC laboratory in Shenzhen for the past three months, along with extensive reading of English-language instrument manuals, referencing numerous Chinese and English EMC standards, and consulting with engineers and testers in the laboratory, this essay aims to provide comprehensive insights. By addressing questions such as what EMC is, why EMC testing is necessary, which products require EMC testing and what items need to be tested, the essay delves into the unique requirements of EMC testing facilities and details the process of conducting EMC testing for USB flash drives. In addition to answering these questions, the essay explores the theory and methods of EMC testing for IT products in depth, analyzing the origins of electromagnetic compatibility issues and discussing various testing items and problem-solving approaches. Throughout the process of writing this essay, the author undertook tasks such as studying EMC testing standards, learning the basic operation of spectrum analyzers and measurement receivers, conducting EMC testing for USB flash drives using these instruments, summarizing the principles and procedures of EMC testing, analyzing test data, and proposing corrective measures. Keywords: Electromagnetic Compatibility (EMC), Anechoic Chamber, Radiated Emissions, Electrostatic Discharge.
