摘要

我们评估了基于交流可编程约瑟夫森电压标准(AC-PJVS)和改进的数字电压表(DVM)的10 Vrms波形合成的差分采样测量的不确定度。由于采样定时器的误差大大减少与外部20mhz频率参考的DVM。对校准器产生的10 Vrms正弦波进行差分采样测量时，B型不确定度要求小于1 μV/V。

Uncertainty evaluation of sampling measurement system using AC-programmable Josephson voltage standard

We have evaluated the uncertainty in the differential sampling measurement of 10 Vrms waveform synthesis based on an AC-programmable Josephson voltage standard (AC-PJVS) with a modified digital voltmeter (DVM). The error due to sampling timer is much reduced with an external 20 MHz frequency reference for the DVM. The type B uncertainty level of smaller than 1 μV/V is expected for the differential sampling measurement of a 10 Vrms sine wave generated by a calibrator.
