Methods and Techniques for EMC Testing

Date：2023-07-07 15:50:00Views：239

EMC electromagnetic compatibility testing is a testing method used to evaluate whether electronic devices can function properly in electromagnetic environments. In modern society, electronic devices have become an indispensable part of people's lives and work. Due to the presence of electromagnetic interference, electronic devices may malfunction or fail to function properly. Therefore, EMC testing is particularly important.

The main purpose of EMC testing is to ensure the compatibility of electronic devices in electromagnetic environments, that is, to be able to coordinate with other devices and environments without interference or being interfered with. When conducting EMC testing, multiple factors need to be considered, such as electromagnetic field strength, frequency range, radiation, and conduction. The testing methods and techniques also need to be adjusted and optimized according to different devices and applications.

Radiation testing

Radiation testing evaluates compatibility by measuring the electromagnetic radiation generated by equipment in an electromagnetic environment. Radiation test needs to use antenna, Spectrum analyzer and other instruments, place the equipment in the EMC test room, and measure the intensity of radiated electromagnetic field of the equipment at different frequencies by adjusting the antenna and Spectrum analyzer. During testing, attention should be paid to external interference in the testing room, such as reflection and scattering of electromagnetic waves.

Conduction test

Conduction testing evaluates compatibility by measuring the sensitivity of equipment to electromagnetic fields. Conduction testing requires the use of signal generators, power amplifiers, cables, and other instruments to apply electromagnetic fields to the input and output ports of the equipment, and to evaluate the compatibility of the equipment by measuring its output signals. When testing, it is necessary to pay attention to the sensitivity of the testing instrument and the interference of the testing environment..

EMC electromagnetic compatibility testing is an important testing method that can ensure the compatibility and reliability of electronic devices in electromagnetic environments. The testing methods and techniques need to be adjusted and optimized according to different devices and applications, while also following certain standards and specifications.
