Abstract :
An ac-dc transfer measurement system based on a programmable Josephson voltage standard (PJVS) is being developed. Performance of the standard with dc and synthesized ac bias has been characterised. The first ac-dc transfer measurement results indicate agreement with conventional standards of the order of 1 muV/V at frequencies up to 40 Hz.
