Abstract: Generally, energy emitted by any source can depend on frequency (f), time (t) and direction ().Quantity ε can be found as operator describing conversion of energy released in source (which depends only on frequency and time) into space-time-frequency distribution of energy in medium surrounding source. If direction, frequency and time features of source are independent of each other, then its emissivity ε can be presented in the form of product of three functions representing separate characteristics describing frequency, direction and time selectivity of source. A co-location system is a system that is an internally compatible system. Such a system can be called a collection of sources of electromagnetic signals and relations between them and their attributes. The relationship between the sources represents their interaction with each other (internal impact) and the impact on the environment (external impact). By co-locating system, we can name an IT or medical device made up of many electronic components with specific distinctive features. In the case of a co-located system, IT or medical devices cooperate to create the entire system. An example of a co-location system is the central unit of a PC computer, which consists of many IT components, and hardware interfaces placed in one casing creating the entire IT system. Another example of a co-location system is a cardiac monitor with the ability to write data to a USB device using a hardware interface. The cardio monitor is a specialized medical device that is used to monitor the most important vital parameters of the examined person. It is a device containing many components, and hardware interfaces placed in one casing.The article presents the method of determining the distinctive features for modern IT and medical devices located on the European Union market based on compromising emission. The article describes the method of identifying hardware interfaces of IT or medical devices that uses radiated compromising emission. In addition, the article presents the results of measurements regarding the use of the developed method to identify the USB2.0 serial interface.The developed measurement method can be applied to all hardware interfaces located in the IT and medical devices. But the article focuses on one of the selected hardware interface - USB2.0.
