摘　　要：８８０２超低频标准相位产生器采用数字技术，用Ｄ／Ａ变换方法产生正弦信号，由单片机控制频率和相位，频率由晶振综合产生，相位可数字预置，频率准确度高至±５×１０￣（－６），相位准确度高至±０．０００２°。介绍了主要技术指标、工作原理、技术特点和误差分析等。In 8802 ultra-low frequency phase standard generator,digital technology is adopted,in which D/A translator is applied togenerate sine signal.Asingle chip microprocessor is used to control the frequency and phase. The fre-quency is synthesized by a crystal oscillator. The phase can be preset digitally by the keyboard on the instrument.The accuracy of frequency can be up to 5 ×10￣(-6) , the accuracy of phase can be up to 0. 000 2°,This paper introduces the instrument’s main specification,principles of operation,technical features and error analyses.
