More Introduction

1. Introduction to Electromagnetic Compatibility Testing

The electromagnetic compatibility laboratory is a special type of laboratory established for electromagnetic compatibility tests. First, explain the basic concept of electromagnetic compatibility: it refers to the ability of electromagnetic systems and subsystems to work normally in their respective electromagnetic environments without reducing their performance due to electromagnetic interference. In order to verify whether the EMC design of electronic and electrical equipment is good, it is necessary to test the emission interference, transmission characteristics of various electromagnetic interference sources, and whether the interfered equipment can withstand the load during the whole process of research and development, and verify whether the equipment meets the relevant electromagnetic compatibility. Standards and Specifications.

Electromagnetic Compatibility Testing Items and Standards

Electromagnetic compatibility testing includes electromagnetic interference test (EMI) and electromagnetic immunity test (EMS). The electromagnetic compatibility standard requires that products related to electronic and electrical equipment must meet the radiated interference and conducted interference emission specifications, as well as the radiation tolerance and conducted tolerance specifications.

 

(1) Electromagnetic Interference (EMI, including CE and RE), the main contents of the test are: the test of the conducted interference and radiated interference emission of electronic and electrical products and equipment in various electromagnetic noise environments, and the interference during transmission of various signals. Test of transfer characteristics.

 

(2) The main contents of electromagnetic endurance (EMS, including CS and RS) test are:

1. Radiation tolerance test to electric field and magnetic field;

2. Conduction tolerance test for injected interference of power lines, control lines, signal lines, ground lines, etc.;

3. Tolerance test for electrostatic discharge and various transient electromagnetic waves (surge or electrical fast transient).
