摘要

数字合成交流电压标准的原理已经建立。本文介绍了一种新的交流电压标准，它使用可追溯的直流电压标准作为输入，并在等效均方根电压的不确定度为1ppm的情况下产生交流输出。该系统使用数字合成与所谓的1位数模转换器(DAC)。

An AC voltage standard based on a 1-bit DAC

The principle of digitally synthesised AC voltage standards is well established. This paper describes a new AC voltage standard which uses a traceable DC voltage standard as an input and produces an AC output at an equivalent r.m.s. voltage to 1 ppm uncertainty. The system works using digital synthesis with a so called 1-bit digital to analogue convertor (DAC).
