Abstract :
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.
