摘要
该仪器用来产生超低频标准电压和标准相位。它采用数—模变换的方法产生模拟正弦信号,用参考标准直流电压确定输出电压,具有移相输出和参考输出。介绍了仪器的工作原理和所采取的技术措施,进行了误差分折。
This paper introduces a generator which is designed for gene- rating ultra-low-frequency standard voltages and phases.It generats an ana- log sinewave signal with the method of D/A converting,provides a refe- rence output and a phaseshift output.The output voltage is defined by a reference standard DC voltage.This paper introduces the principle of operation and the technical methods used by the instrument.It also provi- des the error analysis.
