| Zusammenfassung | A practical dc voltage standard with output voltages UHTS from 0.1 V to 10 V using high temperature superconductor (HTS) arrays of Josephson junctions cooled to 77 K was characterized. HTS arrays with increased current margins and the voltage divider with a high stability of the divider’s coefficients enable stable and reproducible automated calibration of the new HTS standard. The direct comparison of U.Sub.HTS against the voltage generated on an array of niobium Josephson junctions cooled to 4.2 K reveals the agreement of voltages at 1 V level with a Type A uncertainty equal to a few parts in 108. |
