摘要
This paper describes a compact, portable, high-precision voltage standard based on 1V programmable Josephson Array. The accuracy of the system is estimated to be better than 4nV. The system can realize the fully automatic measurement of voltage reference, as well as its weight and volume are reduced. In August, 2007 this system was carried to PTB, Germany to make a comparison. The difference is about 1 nV.
