Electromagnetic Compatibility
Due to the rapid development of technology, the use of electronic devices has increased and disseminated, resulting in industrial accidents such as increased concentration of electromagnetic waves and communication problems and device malfunctions. To prevent these disorders, countries around the world are tightening regulations on electromagnetic disturbances. In line with these regulations, the NTREE Testing Lab. has deployed a variety of testing equipment to provide services for electromagnetic testing.
