摘要：

A portable 10 V Josephson voltage standard as a reference for direct comparisons of stationary Josephson voltage standards is useful for checking parameters of the two systems being compared, often reducing the time necessary to achieve good results. This article presents special design features, such as superconducting filters, array parameters, and bias source construction of a portable Josephson voltage standard which can be carried as hand luggage by one person. The system has already been used for direct comparisons with uncertainties at 10(-10) level.
