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.
