Abstract

A 10 V programmable Josephson voltage standard (PJVS) system has been successfully set up at Center for Measurement Standards (CMS) in 2011. In order to evaluate the performance of this system, we indirectly compared the new PJVS system with the conventional JVS (CJVS) system by using a Zener reference. The voltage across the 10 V terminal of this Zener reference is measured by these two systems individually. Comparison result shows that the difference between the voltages measured by PJVS and CJVS systems is far smaller than the uncertainty of the CJVS system after cancelling the voltage offset of the circuit.
