Types of Testing and Certification
EMC/EMI Testing
Basics
- EMC = Electromagnetic Compatibility
-
EMI = Electromagnetic Interference
-
EMC testing ensures that a product:
- (emissions) does not emit excess electromagnetic energy
- (immunity) does not malfunction when exposed to excess electromagnetic energy (radio frequency interference, RFI)
-
EMC testing typically tests the following properties:
- emissions
- conducted emission
- radiated emission
- flicker and harmonic
- immunity
- conducted immunity
- radiated immunity
- emissions
Standards
Conducting the Testing
- anechoic chambers (AC)
- semi-anechoic chamber (SAC)
