The paper deals with the problem of estimating the information security of data exchange through the USB interface with regard to compromising electromagnetic emanations. There is proposed a specialized procedure for detecting
and measuring the intensity of informative components of compromising electromagnetic emanations. It is based on the formation of the specialized in-formation packets in the data exchange channel, their transmission being
accompanied by the appearance of radio emissions with a linear spectrum. The concentration of power generated by compromising electromagnetic emanations in a set of narrow-band radiations provided by such testing facilitates
their detection against the background of other components of compromising electromagnetic emanations having the other sources of origin. Recommendations are given on the choice of testing length in order to maximize the
probability of capturing signal samples.
