Abstract

The paper presents an introduction of an advanced method for calibration of high-frequency instruments, such as oscilloscopes, frequency counters and function generators that operate at the frequencies between 1 MHz and GHz range. Based on conducted thorough survey of the needs for calibration of high-frequency measurement devices in the region of Southeast Europe, and the identified calibration and measurement capability gap in comparison to the international metrology offer, the Laboratory for Electrical Measurements at Ss. Cyril and Methodius University in Skopje developed new methods, following the general recommendations of the EURAMET cg-7 Calibration Guide. An original approach in the design of the experimental procedure, and a novel data fusion concept for the evaluation of the measurement uncertainty is deployed. The paper also investigates and resolves some challenges of setting up an unbroken measurement traceability chain, and uncertainty estimation for calibration in the domain of high frequencies. The established and accredited calibration capabilities are essential for the region of Southeast Europe, where the metrology facilities for the calibration/testing of high frequency electronic devices are inadequate to meet the conformity assessment needs of the quickly growing automotive supply chain sector, and the needs of other electrical and electronic industries.
