Abstract

We are integrating an AC waveform source into our Programmable Josephson Voltage Standard system (PJVS). The objective is to provide a convenient, highly automated quantum-referenced source for ac voltage metrology that does not require the use of a thermal voltage converter. The stability of the AC waveform is inferred from the DC voltage reference. The accuracy of the AC waveform is measured utilizing the differential sampling method with a PJVS step-wise synthesized waveform as a reference. Preliminary results show AC waveform stability, primarily due to voltage noise, about one order of magnitude less than measured previously with commercial calibrators.
