摘要

本文介绍了基于约瑟夫森采样电压表进行精密功率校准的系统设置。将电压源和电流源产生的波形加到被测功率计上，转换成1 V级电压信号，用单个约瑟夫森电压表测量，不确定度(k = 2)小于0.5 μV/V。

Power calibration system based on Josephson sampling voltmeter

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.
