Radiated Immunity Testing

Radiated immunity testing, also known as radiated susceptibility testing, is one of the four primary EMC tests methods, along with radiated emissions, conducted immunity, and conducted emissions. This test evaluates an electronic device’s ability to resist the electromagnetic interference (EMI) that emanates from surrounding electronic devices.

EMC radiated immunity testing tells manufacturers and consumers whether a DUT can handle the stray EMI that comes from any electronic device in the vicinity. This interference comes from common sources, such as phones, computers, and power lines.

Failure within an electronic system can result in weakened performance, data loss, or complete system failure. When applied to MIL and AERO applications, this can be extremely costly. A particularly costly example would be if the inner workings of a rocket were to malfunction, causing it to blow up.
