Electromagnetic compatibility (EMC) is the branch of electrical engineering that focuses on protecting electronic devices from the interference of electromagnetic energy. The unintentional generation or reception of electromagnetic energy may cause electromagnetic interference (EMI) and damage the equipment. Along with the steep and continuous increase in electronic device usage comes a corresponding increase in the possibility of interference, making EMC testing more crucial than ever.

The four types of EMC testing include: conducted immunity, conducted emissions, radiated immunity, and radiated emissions. Specific standards have been developed to ensure safety and repeatable results when testing equipment that must be followed. IEC (International Electrotechnical Commission), ISO (International Organization for Standardization), and CISPR (International Special Committee on Radio Interference) work individually and together to create these standards in order to provide solutions to current global change. Our EMC and EMI testing equipment has been designed to fulfill these specific test standards such as MIL-STD-461, EN/IEC-61000-4, and CISPR.

Developers of automotive, medical, defense, aerospace, and consumer electronics technology all rely on EMC testing to ensure devices meet strict industry requirements.

Avalon Test Equipment carries a wide variety of EMC test equipment ranging from ESD guns and RF amplifiers to immunity testers. Browse our inventory by category to fulfill specific testing requirements and Test With Confidence®.
