FIELD: radio engineering. ^ SUBSTANCE: invention is related to the field of equipment design, in particular to algorithms of modules installation sequence in digital radio electronic means. In process of operation of radio electronic means (REM) their serviceability may be deteriorated by effect of electromagnetic fields (EMF). Besides REM themselves and their components may be sources of EMF radiated into external space, which may affect operation of surrounding equipment and components of instruments. Method currently available can not minimise mutual effect of structural elements inside developed device, which may result in reduction of device noise immunity at high and ultrahigh frequencies. Technical result of invention is achieved by the fact that in design of electronic units of digital radio electronic means electromagnet radiation is taken into account, which is created by structural elements (modules) of these units, in the form of particular index of electromagnet interaction between modules, which is produced by measurement of electromagnet radiation spectrum produced by structural elements (modules) of units. Modules in device are installed serially, besides, for another installation from multiple uninstalled modules the one is selected, with which function is maximised, where F1i is particular index of i module connection to other modules, F2i is index of heat mode quality, F3i is particular index of electromagnet radiation between modules, R1, R2, R3 are weight coefficients. ^ EFFECT: higher noise immunity of digital radio electronic facilities. |
