Show affiliationsA Josephson voltage standard (JVS) from the BIPM, incorporating a PTB 10 V programmable array, has been compared with a JVS from the LNE, operating with a conventional hysteretic array. The metrological characteristics of both JVSs were carefully studied. We report on the experiments performed for this comparison and on the uncertainty components. The final comparison result is (UPJVS − UJVS)/UJVS = −3.2 × 10−11 with a relative total combined standard uncertainty of 6.1 × 10−11 (k = 1).
