EMI And EMC Testing

Image
EMI and EMC EMI (Electromagnetic Interference) means disrupting the operation of an electronic device placed close to the electromagnetic energy of an external electrical source (natural or man-made). Disruption may cause the failure of the device, or the device may not be able to function properly. EMI is, sometimes, referred to as RFI (Radio Frequency Interference).  EMI sources can be natural or man-made. Natural sources include solar radiation, electrical storms, etc., while man-made sources include other electrical devices like switch-mode power supply, the internal circuitry of personal computers, etc. EMC (Electromagnetic Compatibility) means enabling a device to function properly in its intended environment in the presence of EMI sources. This device is known as EMC compliant. EMI or EMC Testing Testing is essential as it ensures that a device caters to the required standards. EMC pre-compliance and compliance testing are performed by companies to ensure EMC/EMI complianc...
