摘要

基于脉冲驱动约瑟夫森任意波形合成电压标准，设计了一套交流电压校准测量装置。该器件主要由交流约瑟夫森量子电压标准、锁相放大器、信号发生器和配套测量软件组成，实现1kHz 1V(均方根)交流电压测量，扩展不确定度(k = 2)不大于$5.0 \ × 10 ^{-6}$。

AC Voltage Measurement Device Based on AC Josephson Quantum Voltage Standard

Based on the pulse driven Josephson arbitrary waveform synthetic voltage standard, a set of measurement device is designed to calibrate AC voltage. The device is mainly composed of AC Josephson quantum voltage standard, phase-locked amplifier, signal generator and supporting measurement software, which realize the AC voltage measurements of 1V(root mean square)at 1kHz with expanded uncertainties (k = 2) of no more than $5.0 \times 10 ^{-6}$.
