Abstract

We present the first dc comparison of a programmable Josephson voltage standards and a pulse- driven Josephson arbitrary waveform synthesizer (JAWS) at 3 V. Both devices are mounted side- by-side on the cold stage of a cryocooler. The relative agreement achieved was better than 1 part in 108. This measurement allowed us to identify systematic limitations of the JAWS system. An undesired current injection from the JAWS isolation amplifier in the measurement circuit is currently responsible for an error voltage of a few nanovolts.
