An Overview of the Josephson Voltage Standard Interlaboratory Comparison
A majority of Josephson Voltage Standard (JVS) interlaboratory comparisons have been performed by using Zener voltage transfer standards and a protocol based on the Measurement Assurance Program (MAP) with uncertainties in the range of a few parts in 108 at 10 V that are limited by the Zener characteristics. In order to improve the uncertainty of the comparison, protocols using a compact Josephson voltage standard (CJVS) as the transfer standard have been developed. The uncertainty using the CJVS in the comparison can be in the range of a few parts in 109 at 10 V. The array to array direct comparison using the conventional JVS or programmable JVS (PJVS) can further improve the uncertainty of the comparison.
