Justification of the Relevance of Developing a Test Program for Special Studies of the DisplayPort Interface

The purpose of the research presented in the article is to improve the efficiency of conducting special studies of the DisplayPort interface based on the study of characteristics for the development of test programs. To do this, the possibility of intercepting the side electromagnetic radiation of this interface is investigated, the search for informative signals from the interface is carried out, and their attenuation at various distances is investigated. The parameters of the informative signal from the DisplayPort interface are analyzed on the oscilloscope in automatic mode. The relevance of the development of special programs is justified. To confirm the relevance of this study, the measurement of electromagnetic fields and the search for informative signals were carried out by various special technical means in the frequency range from 0.009 to 12000 MHz. Informative signals were detected at 10 frequencies from the investigated technical means, which indicates the existing technical channel of information leakage. To achieve the goal of the study, the amplitude and time parameters of the informative signal were analyzed using a digital oscilloscope. The result of the pulse duration and period is obtained, which is necessary for better and more efficient performance of special studies on the mode of information output to the monitor screen via the Dis-playPort interface.
