The paper describes the theory and the experimental results for the synthesis of precision waveforms by using the pulse-width modulation of the power of the microwave, which drives the superconductor–insulator–normal metal–insulator–superconductor Josephson array. The synthesized sine waveform has a high precision. Its harmonic content was determined to be less than 0.003%. This degree of harmonic content is in agreement with the theory.
The paper describes the principles of construction of modern standards in the field of electrical units with reference to quantum effects and fundamental constants in accordance with the new definitions of the SI system of units. The description of the methods used to build a quantum standards, description of the used measurement quantum transducers, modes and operation principle the experimental setup of the reference complex studied in this work. The description of the software developed for this task is given. The method of measurements and the results obtained in the course of experimental studies, which are in good agreement with theoretical studies, are described. Conclusions and tasks for future research are formulated. Field of application – metrology of measuring instruments of electrical units.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
