Abstract:
Based on 89C52 SCM ( Single-Chip Microcomputer) ，we make DDS core plate /chip AD9833 by using direct digital frequency synthesis． We design one waveform generator module that has the function of frequency measurement， which can produce sine wave，triangular wave，and pulse． It has 0. 1 Hz － 10 MHz frequency of output waveform，0. 1 Hz － 20 MHz range of measurement frequency，function of automatically changing frequency measurement，and output waveform less distortion and more accuracy of frequency measurement． This module can be used as the parts of virtual instrument for wave production and frequency measurement，as well as an independent signal generator with the function of frequency measurement，or as an accessory for wave production of experimental system and frequency measurement in current SCM．
