Abstract

A two-way Josephson voltage standard (JVS) direct comparison between the National Institute of Standards and Technology (NIST) and the National Research Council (NRC) has been conducted. The process consists of two comparisons, one using NIST designed hardware and software and the other using NRC designed hardware and software. The results of the two comparisons are in agreement to within 0.7 nV and their mean indicates that the difference between the two JVSs at 10 V is -0.28 nV with a pooled combined uncertainty of 2.07 nV (k = 2).
