| 摘 要： | 随着现代科技的发展，信息传输系统的工作速率不断拓宽，要求用于其可靠性、稳定性评测的误码率测试设备具备超宽速率的测试图形产生能力。本文提出了一种用于误码率测试设备的超宽速率图形产生方法，该方法将50 Mb/s～60 Gb/s的超宽速率分解为四个速率段，并通过高速开关实现输出图形信号的切换。文中基于FPGA（现场可编程逻辑门阵列）+多级MUX（多路复用器）的图形产生架构［1］搭建了测试系统，通过对整个工作速率范围进行分解，最终实现了一路50 Mb/s～60 Gb/s范围内超宽速率测试图形信号的产生。

| Abstract: | With the development of modern technology,the working rate of information transmission system is constantly expanding,so Bit Error Rate Tester must have the ability of generate Ultra-wide rate test pattern for reliability and stability evaluation.The article propose a method for generate Ultra-wide rate test pattern,it break the Ultra-wide rate test pattern of 50 Mb/s～60 Gb/s down into four pieces,and use high-speed switch to choose output pattern.In the article,we built a test system based on FPGA(field-programmable gate array) + multi MUX(multiplexer) architecture,by decompose the whole range of working rate,finally generate a Ultra-wide rate test pattern of 50 Mb/s～60 Gb/s. |
