At a later date, pulse modulation capability will be added for testing above 1GHz. 1.2 This document provides the component design and test engineers with a test procedure and the performance requirements necessary to evaluate the immunity of electronic devices to radiated electromagneticfields early in the design stage as well as pilot and production stages. Ensuring electromagnetic compatibility early in the development stage wi
