摘要
采用SOPC技术在FPGA平台上设计出数字信号传输性能分析仪,数字信号发生器和数字信号分析各使用一块Cyclone II开发板设计实现.基带信号的码元速率可从1 bps到250 Kbps连续可调.信号分析端使用多个窄带数字滤波器分段滤波的方法获取位同步信号,并在示波器上显示眼图.测试表明,通过眼图质量可以准确的分析出数字信号传输系统的性能.
The transmission property analyzer for digital signals is designed on FPGA platforms by SOPC technology,in which digital signal generator and analyzer are implemented on each development board respectively.In the signal generator side,the rate of base band can be adjusted continuously from 1bps to 250Kbps.In the signal analyzer side,several narrow bandwidth filters are used to obtain synchronous signals,which can help show the eye pictures.Experimental test proves that the transmission property can be analyzed accurately by checking the eye picture′s quality.
