The article aims at the following two aspects of function generator, decreasing the traditional costing and promoting the stability of low frequency of function generator. The integration of FPGA and SCM 51 is designed hereby to make various signaling functions at 0.596Hz happen. SCM 51 controls the signal frequency, waveform and amplitude, whilst LCD displays the relevant information of signaling functions. It is possible for the generator designed to maintain, to upgrade the software so as to realize more accurate signal functions and to meet the needs at different occasions. The article here also contributes to the farther reform of nowadays＇ higher education.
