Abstract :
This paper describes the first measurement results with a square-wave based Josephson ac voltage standard. Using a planar multijunction thermal converter as a reference the accuracy was found to be in the μV/V range at 1 V level at 62.5 Hz and 1 kHz. A systematic error of 1.3 μV/V was observed.
