数字视频接口信号测试方法

DVI作为一种优秀的数据接口标准的提出不仅解决了显示器高分辨率和高刷新率问题,而且提高了稳定性和显示性能并进一步降低了平板显示器的成本。本文只对DVI接口的设备中的高速信号检测进行了探讨,简略介绍了标准检测的过程,重点介绍在低设备的环境下对接口电路和链路数据传输检测的一些实用方法。

A Method of Testing the Digital Visual Interface Signal

DVI was proposed as a fine data interface standard that resolved the problem of high resovation and high refresh rate of the display monitors,it not only helped to improve the stability and display performance,but also lowered the cost of flat - panel displays greatly.This article discusses the testing of high- speed signals produced by the devices that employ DVI interfaces.It briefly describes the standard test procedure by focusing on some practical methods used in the testing of interface circuit and link circuit data transfer under the low- speed equipment environments.
