Electromagnetic compatibility Test (EMC)

In order to prevent interference with other electronic equipment due to electromagnetic noise emitted from the electronic equipment, the emission amount of electromagnetic noise is controlled to be below the standard level (EMI, electromagnetic interference), and the performance of the electronic equipment is maintained even in a strong external electromagnetic noise environment (EMS, electromagnetic susceptibility) to ensure electromagnetic compatibility.

Subjected items

Computer products, USB products, Mobile phones, Wireless devices, lighting devices, Broadcast receivers, Home appliances, Multimedia devices, Navigation devices, Control devices, etc.


Automotive Test (KN41)

The after-market electronic device mounted inside the vehicle is becoming diverse due to the advancement of the technology, the electromagnetic wave generated from the product can affect other devices, and the product with low immunity in electromagnetic environment may be damaged to human life due to malfunction, so the evaluation should be done on a strict basis in the development process.
