Operation of NIST Josephson Array Voltage Standards

Comparison of the Josephson Voltage Standards

A comparison of the 10 V Josephson array voltage standard of the Bureau International des Poids et Mesures (BIPM) was made with that of the National Institute of Standards and Technology (NIST), USA, in March 2009. For this exercise, three different measurement methods were carried out: the two different options of the BIPM.EM-K10.b comparison protocol as well as the measurement protocol applie...

Josephson Voltage Standards Comparison between Cenam and Nist at 10 V Level

Abstract: A comparison of Josephson Voltage Standards (JVS) between the National Institute of Standards and Technology (NIST) and the Centro Nacional de Metrología (CENAM) held at CENAM from 21 to 23 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 NIS...

Bilateral Comparison of Dc Voltage References between Cenam and Nist

A comparison of Josephson Voltage Standards (JVS) between the National Institute of Standards and Technology (NIST) and the Centro Nacional de Metrología (CENAM) held at CENAM from 21 to 23 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 dif...

The Calibration of dc Voltage Standards at NIST

This document describes the procedures used at NIST to calibrate dc voltage standards in terms of the NIST volt. Three calibration services are offered by the Electricity Division: Regular Calibration Service (RCS) of client standard cells at NIST; the Volt Transfer Program (VTP) a process to determine the difference between the NIST volt and the volt as maintained by a group of standard cells ...
