摘　　要：文章主要介绍程控正弦功率电压源和电流源校表仪的原理。该仪器采用以８９Ｃ５２为核心的单片机系统,用软件编程来产生频率可调的正弦信号,显示部分由８２７９专用键盘显示管理模块来实现人机接口,提高了校表仪智能化程度和校表仪准确度。This paper describes the principle of sin voltage source and current source that can be programme controlled. With 89C52 as the core of the single-chip system. This equipment adopts software to generate sin signals whose frequency can be regulated. The display part is implemented by 8279 specialized module to realize the man-machine interface,which has greatly improved system's intelligence and precision.
