The structure of modern electronic technology facilities include digital blocks, which consist of radio-electronic components (REC). Conducting quality control of the technical state of the digital REC depends on the method of diagnosis. A promising method of diagnosing REC is a non-contact induction method of diagnosis. Summary contactless inductive method (hereinafter - method) diagnosing digital blocks is that the parameters are used as a diagnostic signal parameters, which are induced at the terminals of the conductive parts of the measuring coil from a test unit to a digital signal. Under the current carrying element is understood the power cord digital unit (positive or cabinet). The work is accompanied by a digital unit change in the magnetic field around the wire supply feeding a diagnostic test. Is input REC test sequence xi triggers the element, respectively, with sales in its function. When this occurs on a SDS corresponding sequence of signals (feedback) ӯк.i . If the input sequence contains xi a functional screening test, the total response of the rivers can be represented as a sequence of response elements on FPT ӯфпт.i and redundant sets ӯнд.i . This total response ӯк.i.ет has reference to the case of a fully serviceable REC.
