Abstract: A device and a method for monitoring and analysis utilize unintended electromagnetic emissions of electrically powered components, devices or systems. The emissions are received at the antenna and a receiver. A processor processes and measures change or changes in a signature of the unintended electromagnetic emissions. The measurement are analyzed to both record a baseline score for future measurements and to be used in determining status and/or health of the analyzed system or component.
