“…Ponadto stabilizacja temperatury modułów w obudowie PXI jest niewystarczająca. Dlatego też krajowe instytuty metrologiczne, we współpracy z uczelniami lub producentami sprzętu elektronicznego, podejmują próby konstruowania własnych rozwiązań niekomercyjnych [23][24][25]. W ostatnim dziesięcioleciu niekwantowe mostki impedancyjne wdrożyły do stosowania instytuty metrologiczne m.in.…”

“…Prace nad rozbudową układu mostka cyfrowego w Laboratorium Wzorców Wielkości Elektrycznych Małej Częstotliwości Głównego Urzędu Miar w Warszawie prowadzone są we współpracy z Politechniką Śląską w ramach projektu finansowanego z programu MEiN "Polska Metrologia" w latach 2022-2024. Najważniejszą zaletą i nowością systemu, w porównaniu z alternatywnymi rozwiązaniami [14,16], jest zastosowanie dwukanałowego precyzyjnego syntetyzowanego cyfrowo źródła napięcia przemiennego [24]. Opracował je zespół badaczy z Politechniki Śląskiej w ramach międzynarodowego projektu EMPIR SIB53 AIM QuTE: Automated impedance metrology extending the quantum toolbox for electricity [23,25].…”

The article presents current trends in impedance metrology of the highest accuracy. Attention was paid to digital non-quantum impedance bridges, which have been developed in many European National Metrology Institutes over the last decade. Particular attention in the article was devoted to the digital impedance bridge currently being developed at the Central Office of Measures in Warsaw. The conceptual diagram, system implementation and the progress of work related to the development of this bridge and its implementation in the near future into the national measurement system are presented as well.

“…This facilitates the process of debugging programs and making further improvements. The second group of sources are based on constructions developed entirely by their authors [34][35]. The advantage in this case is the possibility to make an optimal selection of digital-to-analog converters and other analog elements having a significant impact on the metrological properties of the source.…”

This paper presents the concept and some aspects of the physical implementation of a virtual training laboratory in the field of primary impedance metrology. The creation of a virtual training laboratory provides a novel method of disseminating metrological knowledge and expertise in a practical way and at a low cost. It will expose new users to the live experience of operating a digital impedance bridge thus helping to encourage the uptake of this novel and useful impedance measurement technology. The virtual training laboratory was developed as part of the EMPIR projects VersICal 17RPT04, A versatile electrical impedance calibration laboratory based on digital impedance bridges, and GIQS 18SIB07, Graphene impedance quantum standard.

“…The latter are used in coaxial structures to deliver microwave power (typically from 20 to 75 GHz) to excite the array of Josephson junction chips. To achieve the high performance of devices (by good impedance matching) or to increase the accuracy of the metrological standard, multilayer constructions require precise knowledge of electrical impedance parameters such as inductance and resistance, which are one of the most important parts of the electrical metrology [ 12 , 13 , 14 ]. Furthermore, the design and optimization process requires tens of thousands of repetitions when, for example, the Monte Carlo uncertainty evaluation method is used [ 15 ].…”

This paper presents a fast and computationally stable analytical algorithm used to perform the characteristic impedance of cylindrical multilayer waveguides used in high-precision sensors and apparatuses. Most of the algorithms used for the calculation of the characteristic impedance of those waveguides are based on approximations. Their application is limited to waveguides with a certain (usually small) number of layers. There may be insufficient layers, especially when coaxial waveguides are part of a precise measurement device. This article presents a numerically stable analytical algorithm using modified scaled Bessel functions to perform the characteristic impedance and the components of cylindrical coaxial multilayer waveguides. The results achieved by the extracted algorithm were compared to the results obtained by simulation using finite element method (FEM) software and the current method, whose main drawback is the fictive sublayers, which significantly increase the computation time. The excellent agreement between the results confirmed the precision of the algorithm and the time required for the calculation was reduced several times.
