Evaluation of a new Prototype of Secondary Voltage Standard with a Programmable Josephson Voltage Standard
This paper evaluates the short-term and long-term performance of a new type of dc secondary voltage standard at 10 V by direct comparison to a programmable Josephson voltage standard. Allan deviation measurements indicated a noise floor of 4.5 nV, enabling potential new applications in voltage metrology and possibly reducing uncertainty along the dissemination chain from primary calibration laboratories to calibration laboratories.
