electromagnetic compatibility (emc) is the branch of electrical engineering concerned with the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (emi) or even physical damage in operational equipment. the goal of emc is the correct operation of different equipment in a common electromagnetic environment.
emc pursues two main classes of issue. emission is the generation of electromagnetic energy, whether deliberate or accidental, by some source and its release into the environment. emc studies the unwanted emissions and the countermeasures which may be taken in order to reduce unwanted emissions. the second class, susceptibility is the tendency of electrical equipment, referred to as the victim, to malfunction or break down in the presence of unwanted emissions, which are known as radio frequency interference (rfi).immunity is the opposite of susceptibility, being the ability of equipment to function correctly in the presence of rfi, with the discipline of "hardening" equipment being known equally as susceptibility or immunity. a third class studied is coupling, which is the mechanism by which emitted interference reaches the victim.
emc is an important technical index for electrical and electronic equipment, which is not only associated with product safety and reliability as well as protection of electromagnetic environment. therefore, emc compliance is essential for accessing the international market.
staffed by senior emc specialists, c&k testing is able to render tailored test plans for you in a prompt and professional manner. meanwhile, debug service is also available if any problem occurring during product testing so that you can pass the test and certification smoothly. please feel free to contact us at if you have any needs or questions.
