JOSEPHSON VOLTAGE STANDARDS COMPARISON BETWEEN CENAM AND NIST AT 10 V LEVEL

A comparison of Josephson Voltage Standards (JVS) between the National Institute of Standards and Technology (NIST) and the Centro Nacional de Metrologia (CENAM) held at CENAM from 21 st to 23 rd of March 2006 is reported. The comparison was made at the 10 V level by measuring four Zener references using the JVS of CENAM and the transportable Compact Josephson Voltage Standard (CJVS) of NIST. The difference between the measurements was -38 nV with an uncertainty of 42 nV at 95 % level of confidence.
