1. An apparatus that determines a state and/or a condition of an unpowered electrical or electronic device, comprising:

  • a waveform generator that generates a waveform;

    a first antenna that transmits electromagnetic energy containing said waveform in a direction of the electrical or electronic device;

    a second antenna that receives electromagnetic artifact(s) that are re-emitted from the electrical or electronic device due to excitation thereof with said waveform;

    an RF receiver; and

    a controller that controls said RF receiver, said controller comprising;

    one or more processors, andnon-transitory computer readable medium containing executable or computational instructions that cause said one or more processors to perform the steps of;

    developing an electromagnetic emission signature of the electrical or electronic device, said electromagnetic emission signature containing said electromagnetic artifact(s),analyzing said developed electromagnetic emission signature, anddetermining the state and/or condition of the electrical or electronic device based on said electromagnetic artifact(s) present in said electromagnetic emission signature.
