With the rapid development of the popularity of electronic products in people's lives, there are more and more opportunities for mutual influence and interference between electronic products, ranging from partial functional abnormalities of products to personal safety caused by product protection function failure. Therefore, the requirements and standards for electromagnetic compatibility testing of products are also becoming higher and higher. Simply understood as EMC, it refers to the ability of a device or system to operate in its electromagnetic environment in accordance with requirements without causing unbearable electromagnetic interference to any device in its environment
