Abstract

In the paper, analysis of the measurement infrastructure for examination and calibration of measuring instruments (oscilloscopes and counters) at extremely high-frequencies at the international, regional and national levels is made. The analysis is carried out within the framework of the scientific research project “Development and Upgrade of Laboratory Resources for Research and Introduction of New Analytical Methods in Electrical Metrology”, which is implemented under the program for financing scientific and research projects of public interest for 2021 by the Ministry of Education and Science of Republic of North Macedonia. The main emphasis of the paper is on the development of a procedure and calculation of measurement uncertainty for the calibration of high-frequency meters, according to Euramet Guideline No.7, Calibration of Oscilloscopes. The paper describes the newly installed reference standard measurement system in the Laboratory for Electrical Measurements at UKIM-FEEIT for calibration of instruments for high frequencies, as well as specific measurement results, evaluation of the budget of measurement uncertainties, and established traceability chain in the field of high frequencies.
