BTF Testing Lab Electromagnetic Compatibility (EMC) introduction

short description:

Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: On the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit; On the other hand, it means that the appliance has a certain degree of immunity to electromagnetic interference in the environment, that is, electromagnetic sensitivity.

Introduction to Bluetooth Technology

The EMC standard system framework of most international organizations adopts the standard classification system of the International Electrotechnical Commission (IEC), which is divided into three categories: basic standards, general standards, and product standards. Among them, product standards are further divided into series product standards and special product standards. Each type of standard includes both interference and anti-interference standards. EMC standards are adopted in accordance with the order of "special product standards → product standards → general standards".
