Radiated Immunity Testing

Radiated Immunity Testing Services

Radiated immunity testing evaluates your product's ability to operate correctly when exposed to radio frequency electromagnetic fields. Compatible Electronics provides comprehensive IEC 61000-4-3 radiated immunity testing for all product categories.

What is Radiated Immunity Testing?

Radiated immunity (also called radiated susceptibility) testing determines whether your electronic product can withstand electromagnetic fields from sources like radio transmitters, wireless devices, and other RF emitters. This testing is critical for CE marking, medical device approval, and industrial equipment certification.
