Ov. Karpov et al., Measurement of a SINIS-type Josephson junction array voltage with respect to the voltage standard based on a SIS-type Josephson junction array, INSTR EXP R, 44(5), 2001, pp. 655-661
An experimental setup for accurate measurement of the voltage difference be
tween two Josephson junction arrays irradiated at different microwave frequ
encies is described. The measurement technique is proposed and the experime
nt is performed. It is shown that the maximum accuracy is achieved at the o
ptimum measurement time depending on both the measurement conditions and no
ise behavior of the test equipment.
