基于触发以分离波形的百兆以太网物理层测试方法

摘要:

以太网是世界上最普遍、应用最广泛的一种计算机网络。其中工业上以太网的测试着重需要关注物理层的情况。本文介绍了一种百兆以太网的物理层测试方法,其关键在于使用了一种3电平眼图分解成两电平眼图的方法和一种用两个眼图的物理层测试的技术指标去等效评价百兆以太网物理层质量的方法。

Abstract:

Ethernet is the most popular and widely used computer network in the world. The testing of Ethernet in industry should focus on the physical layer. This paper introduces a physical layer test method of Fast Ethernet. The key to method are decomposition of 3-level Eye Diagram into two-level Eye Diagram and evaluating the physical layer quality of Fast Ethernet with the technical indexes of two Eye Diagrams.
