  • Accurate voltage standards are crucial for scientific and technological advancements.
  • The AC programmable Josephson voltage standard (ACPJVS) is a key tool for precise voltage generation.

Purpose of the Study:

  • To evaluate a sampling digital voltmeter for comparing two independent ACPJVS systems.
  • To demonstrate the effectiveness of differential sampling for measuring small waveform differences.

Main Methods:

  • Precision measurements comparing AC and DC waveforms from two ACPJVS systems.
  • Utilizing a sampling digital voltmeter for differential measurements.
  • Testing waveform comparisons at frequencies up to 3.6 kHz.
