用约瑟夫森阵列电压标准校准Fluke752A分压箱

Method to calibrate Fluke 752A divider by using Josephson voltage standard

简述了用约瑟夫森阵列电压标准校准 Ｆｌｕｋｅ７５２Ａ分压箱的方法。对于 １０：１和１００：１量程，其比例测量的不确定度分别为１×１０－７和３×１０－７。

In this paper, the method to calibrate Fluke 752A divider by using Josephson voltage standard is introduced. The measurement uncertainties of divider ratio are 1 x 10-7 for 10:l range and 3 x 10-7 for 100:l range.
