EMC testing, also known as electromagnetic compatibility (EMC) testing, refers to the comprehensive evaluation of the interference level (EMI) and anti-interference ability (EMS) of electronic products in electromagnetic fields. It is one of the most important indicators of product quality. The measurement system for electromagnetic compatibility consists of a testing site and testing instruments.
The purpose of EMC testing is to detect the impact of electromagnetic radiation generated by electrical products on the human body, public power grids, and other normal functioning electrical products.
