The goal of EMI testing is to determine whether a product complies with regulations and standards that limit the amount of electromagnetic interference it can emit. EMI vs EMC testingĮMI (Electromagnetic Interference) and EMC (Electromagnetic Compatibility) testing are related but distinct concepts in the field of electrical engineering.ĮMI testing focuses on the measurement of electromagnetic radiation emitted by a device or system, and its effects on other electronic devices and systems. By complying with the FCC EMC regulations, manufacturers can help ensure that their products are robust, reliable, and safe for use in the United States. The FCC EMC regulations are an important aspect of ensuring the reliability and safety of electronic products, and are a critical aspect of product development and certification. To meet the requirements of the FCC EMC regulations, electronic products must undergo EMC testing, which involves evaluating the product’s ability to operate in a noisy electromagnetic environment without causing or being affected by harmful electromagnetic interference. The regulations specify the requirements for radiated and conducted emissions, as well as immunity to electromagnetic interference. The FCC EMC regulations apply to a wide range of electronic products, including consumer electronics, communications equipment, medical devices, and many others. The FCC (Federal Communications Commission) EMC (Electromagnetic Compatibility) is a set of regulations and standards established by the Federal Communications Commission (FCC) to ensure that electronic devices and equipment do not cause harmful interference to other electronic devices or systems. A few examples include electrostatic discharge testing, surge testing, and possible on-site evaluations. A typical testing program consists of various emissions and immunity requirements. 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. Immunity and Susceptibility are used interchangeably and 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.ĮMC testing is performed to ensure that devices are designed and specified to function in electromagnetic environments they will commonly be exposed. The two main methods of classifying these interactions is through Emissions and Immunity.Įmissions are the generated electromagnetic energy that is released into the environment and produced by a device or other source. Our streamlined testing process brings your product from development to end use efficiently in accordance with government, regulatory, military, or industry standards based on your compliance needs.Įlectromagnetic compatibility (EMC) is the interaction of electromagnetic energy generated by electronic equipment and the surrounding environment. We understand that time to market is everything which is why our global testing capabilities and custom testing solutions utilize the latest technology and automation software, helping you meet demanding time-to-market needs. We evaluate your products and systems to any number of electromagnetic conditions in our state-of-the-art EMC labs helping you bring your product from development to end use faster and more cost-effectively. Today, manufacturers face a wide set of stringent compliance challenges to ensure that products do not radiate much energy and are not susceptible to outside interference. Electromagnetic Compatibility testing analyzes the ability of electronic devices to operate as anticipated when in proximity to other electronic devices or in the presence of electromagnetic disturbances that interfere with their intended operation.
