What is EMC?
EMC, or electromagnetic compatibility, is the interaction of electromagnetic energy generated by electronic equipment and the surrounding environment. The three main methods of classifying these interactions is through Emission, Susceptibility, and Immunity.
What are Emissions?
Emissions are the generated electromagnetic energy that is released into the environment and produced by a device or other source.
What is Susceptibility?
Susceptibility can be defined as the interference of electromagnetic energy in the surrounding environment on a device and the tendency of this electromagnetic energy to inhibit proper device functionality.
What is Immunity?
Immunity is the ability of a device to resist the electromagnetic energy in the surrounding environment and prevent interference from inhibiting proper device function.
Why perform EMC testing?
EMC testing is performed to ensure that devices are designed and specified to function in electromagnetic environments that they will commonly be exposed. Testing verifies that a device will function in the presence of electromagnetic interference (EMI), the device will not radiate unacceptable levels of electromagnetic energy, and that a device will not disrupt the function of other nearby electronic devices. A typical testing program consists of various emissions, susceptibility, and immunity requirements, in addition to electrostatic discharge testing, surge testing, and possible on-site evaluations.
