基于FPGA和DDS技术的多通道信号源设计
A Multichannel Signal Generator Based on DDS and FPGA
摘要
Abstract
In order to solve the problem of the low frequency resolution,low frequency accuracy,the long cycle of develop-ment and update and the less signal channel,a multi-function and multi-channel signal generator which is based on DDS technolo-gy with FPGA,high-speed D/A and a low-pass filter as the core is designed and implemented. In the FPGA,the PCI interface con-troller,synchronous clock control module,SRAM controller and DDS module etc are designed. The experiment results show that the system is simple and reliable and can generate sine wave,square wave,triangular wave,saw tooth wave and arbitrary waveform sig-nal. The frequency resolution comes up to 0.01Hz and frequency accuracy is equal or lesser than ±0.1％.关键词
