This paper describes system setup, based on a Josephson sampling voltmeter for precision power calibration. The waveforms generated by voltage and current sources, which are applied to a power meter under test, are transformed to 1-V level voltage signals and measured by a single Josephson voltmeter with a uncertainty (k = 2) less than 0.5 µV/V.
Progress in the development of an evaluation system for thermal-transfer standard based on a Josephson waveform synthesizer at KRISS. The synthesizer adopting a Josephson junction array, which can generate arbitrary stepwise waveforms with a number of the quantum-voltage steps up to 2.5-V level amplitude. With the synthesizer, we have built a sampling voltmeter that measures the differential voltages...
