摘要
Abstract
In order to make the waveform generator for medical electromagnetic navigation system small and convenient,this paper introduces a sinusoidal signal generator using DDS chip AD9833 and digital potentiometer AD5252.Based on the MCU C8051F320,the frequency and phase can be controlled by MCU via SPI communication with AD9833.Besides,the amplitude can be adjusted by IIC communication with MCU and digital potentiometer AD5252.At the same time,the system has developed a host computer interface based on VB for convenient control.The experimental results show that the signal generator is reliable,easy to control with high accuracy output.关键词
