Abstract :
In an extension from their original use as references for measuring dc voltage, Josephson generated voltages from programmable arrays have been employed to measure waveforms differentially. In this paper, the alternative of using these Josephson voltages as a reference for ac-dc difference measurements using thermal converters and sampling techniques is presented.
