Optimization of requirements for measuring instruments at metrological service of communication tools

A method for determination of a minimal value for probability of correct estimation of measurement results (PCEMR), using conditional algorithms is developed. The novelty of the method is in the application of methods of technical diagnostics to the metrological service of communication systems. Namely, metrology and technical diagnostics are related through the fact, that the PCEMR, performed with a measuring instrument (MI) governs the value of the average time for determination of technical state of a communication tool (CT). Derived equations increase the accuracy of estimation of mathematical expectation of a deviation from the true value, which characterizes the technical state of a CT. To illustrate the capability of the method we check whether the digital multimeter Keithley 2000 as a MI is a correct choice for determination of the technical state of a controlling operational subsystem of a high-power transmitter.
