Abstract :
We describe the work towards a setup of a low frequency “Josephson impedance bridge” based on programmable Josephson voltage standards. Tests of ac voltage synthesis and dc voltage measurements of the two programmable Josephson standards have been performed including a direct Josephson dc voltage comparison.
