We are developing a sampling measurement system using AC-Programmable Josephson voltage standard (AC-PJVS) toward low-frequency AC voltage standard below 10 Hz. We succeeded in generating a stepwise-approximated waveform with a root-mean-squared (RMS) value of 10 V by optimizing PJVS operating conditions so far. In the present study, we have measured the sinusoidal waveform with the RMS voltage of up to 10 V using a sampling method. A relative expanded uncertainty of 9 parts in $10^7$ (k = 2) was achieved in the optimized sampling condition when measuring a 10 V RMS sine wave generated by a semiconductor AC voltage source at the frequency of 62.5 Hz. |
