Josephson voltage standard locked sinewaves synthesizer

This paper describes a Josephson voltage standard locked synthesizer where a commercial digital to analog converter is used as a sine wave generator whose output is controlled (in phase and amplitude) by the calculable fundamental of the stepwise sinuisoidal wave generated by a SINIS array. Such a system combines the versatility of a commercial source with the stability and accuracy of the Josephson standard.
