The cost of electronic measuring instruments is influenced by their technical characteristics and design factors. Moreover, this influence is often complex non-linear in nature, which greatly complicates the construction of an adequate cost forecast. When justifying the composition of complex measuring systems, the error can be significant and lead to a non- optimal solution. Therefore, improving the quality of forecasts of measuring instruments cost, that are part of the system for testing special-purpose electronic equipment is an urgent task, which is considered in the presented article. When considering the main approaches to forecasting measuring instruments cost, the apparatus of economic and mathematical methods is applied: mathematical statistics, qualitative analysis of the main characteristics and factors determining the measuring instruments cost, comparative analysis of the technical level of radio-electronic equipment samples, and the analog method. As an example, additive and multiplicative models are considered for practical calculations of the cost of high-frequency signal generators and spectrum analyzers as a function of the technical characteristics of these devices. Corrective functions have been identified, the use of which significantly improves the accuracy of forecast, which proves the feasibility of using such functions in forecast models of the measuring equipment cost.
