Abstract

A comparison between the National Institute of Metrology (NIM) and the Beijing Institute of Radio Metrology and Measurement (BIRMM) Programmable Josephson Voltage Standards (PJVS) at 1 V level was carried out at Changping campus of NIM from November 16 to November 17, 2009. The measured difference voltage between the two PJVS is 2×10^-10 in direct comparison and 4×10^-9 in indirect comparison. The results of this comparison have demonstrated excellent agreement between the NIM and the BIRMM PJVSs.
