Abstract:
This paper presents results of experiments quantifying two systematic errors associated with the calibrations by use of an AC Josephson Voltage Standard: the change in the voltage leads error with the change in the level of probe immersion in the liquid helium, and the effect of the internal inductance of a Josephson array. The measurements were performed at frequencies 100 kHz and above, however, they can be used in evaluating an error budget at lower frequencies.
