Research Abstract

We have optimized an AC Programmable Josephson Voltage Standard(ACPJVS) system and developed the precise measurement method toward ideal AC voltage standard waveform synthesis. We developed the calibration system for commercial calibrators based on a synchronous sampling method and obtained the relative standard uncertainty value of 3.5 ppm at a frequency of 62.5 Hz. With considering the time-base error of the digital voltmeter used, we can expect further suppression of the uncertainty value down to about 1 ppm. As a result of the above experiments, we achieved our original goal of 1ppm at 60 Hz and also obtained prospects for improving uncertainty of the calibration at low frequencies in the conventional AC-DC transfer standard.
