Devices and systems utilized to assess the susceptibility of electronic equipment to electromagnetic fields are a crucial element in ensuring reliable operation within complex electromagnetic environments. These specialized tools generate controlled electromagnetic fields and monitor the performance of the equipment under test to determine its ability to function as intended when exposed to radiation. For example, a signal generator, amplifier, and antenna may be employed to create a radiated field, while monitoring equipment is used to identify any performance degradation in the device being tested.
The application of these test methods is vital for maintaining product integrity and regulatory compliance across various industries. The ability to withstand electromagnetic interference is paramount in sectors such as automotive, aerospace, and medical devices, where malfunctions caused by radiated emissions can have severe consequences. Historically, addressing electromagnetic compatibility (EMC) primarily focused on emissions control. However, as technology has advanced and electromagnetic environments have become more complex, the need for immunity testing has grown significantly. This evolution has led to the development of increasingly sophisticated testing methodologies and corresponding instrumentation.
