Abstract :
Various operational parameters of two different I-V binary programmable Josephson arrays are evaluated and compared within different Josephson array voltage standard (JAVS) set-ups at microwave frequencies around 70 GHz. For this purpose, the investigation of the electrical characteristics of a SINIS-type Josephson array and of an externally shunted SIS-type Josephson array is under way at ten national metrology institutes. The results of the measurements are presented and discussed.
