Scientists from National Measurement Institute of Switzerland (METAS, Wabern), Danish Designated Institute (Trescal, Silkeborg) and Silesian University of Technology (SUT, Gliwice, Poland) successfully implemented the high-stability digital source of sinusoidal voltage in the four-terminal pair digital sampling impedance developed at METAS. The new source enhanced the resolution of the METAS sampling bridge approximately 100 times and substantially improved the speed of the balancing procedure. The source was developed by Marian Kampik (SUT) within an individual Research Exellence Grant, realized within European project „AIM QuTE: Automated Impedance Metrology extending the Quantum Toolbox for Electricity”, granted by European Metrology Research Programme (EMRP).
