- Abstract:
- Firstly, a differential sampling measurement principle is introduced, then based on this principle, we have developed a precision differential sampling system to measure sine-wave sources with the use of a quantumaccurate ac programmable Josephson voltage standard. And switching measurement technology is adopted in the differential sampling system design. By analyzing the error source of the differential sampling system, a mathematical model is established and the error transfer function is derived.We have performed a variety of measurements to evaluate this differential sampling system. Firstly, the basis of FLUKE 5720A transition process is analyzed, and the selection scheme of sampling window is described. After averaging, the uncertainty obtained in the determination of FLUKE 5720A 1 VRMS amplitudesine wave at 60 Hz is 0.3 µV/V (type A), the uncertainty obtained in the determination of PJVS 1 V RMS amplitude sine wave at 60 Hz is 0.05 µV/V (type A).
