Large series-connected arrays of junctions, which cannot be individually accessed, are usually tested by measurement of the current-voltage characteristic (Fig. 1). The distribution of the DC Josephson currents is determined by the curve A-B and the number of short-circuited junctions inferred from the difference between the known junction number N and the apparent number n = Vo/Vg, where Vg is the gap voltage for a single junction.
