1. A method for authenticating an electronic device under test (DUT) of a type of DUT, the method comprising:
imparting, to the DUT, first voltage tones proximate a frequency of interest associated with the type of DUT;
determining, using measurement responses of the DUT to the voltage tones, an electronic signature of the DUT; and
determining that the DUT is authentic in response to the electronic signature of the DUT substantially matching an electronic signature of an authentic DUT of the type of DUT wherein the frequency of interest is identified for the type of DUT wherein the electronic signature of the DUT is determined using a plurality of frequencies of interest associated with the type of DUT and the measurement responses to the first voltage tones proximate to each of the plurality of frequencies of interest.
