OPEN ALLIANCE TC2和TC9线束以太网测试标准？
联盟中TC2汽车线束以太网线束定义标准：
100BASE-T1 Ethernet Channel&Components
100BASE-T1 offers a way to introduce modern signal processing in automotive,which allows optimal usage of the available channel characteristics.
TC2 goals are as follows:
Define deterministic and robust transmission channel between the Ethernet enabled electronic control units.
Specify requirements for Common Mode Choke(CMC),cables,connectors and harness manufacturing
The solution needs to be reproducible in high volumes,at high quality and meets cost targets of today’s global automotive logistics
TC1 and TC2 in combination provide for the complete 100BASE-T1 application.
联盟中TC9汽车线束以太网线束定义标准：
Automotive Ethernet Channel&Components
The goal of TC9 is to specify electrical requirements and test procedures for channel and components in conformance to the link segment requirements of IEEE 802.3 automotive Ethernet standards at various speed grades.
The scope includes:
Communication channel
Connectors,cables,cable assemblies and wiring harnesses
Measurement setup and procedures
Electrical requirements
EMC environment
通过OPEN联盟这两个协议标准来看，TC2就是100M,TC9就是1000M.除了常规使用KEYSIGHT的5071C等RF矢量网络分析仪可以做。目前还有哪些设备可以满足此项测试要求呢？
以上是实验室常规测试方法：
通过治具严格按照测试标准的方法一步步进行测试。其步骤比较繁琐，一步错，就不能保准数据的准确性。
目前有一种可替代的测试设备，简单易操作。
一步到位可以测试出所有的线束标准中需要的参数。
总之，随科学技术的发展，我们的选择行很高，不简单的局限于传统的繁琐的测试方法以及步骤。AEM线束测试仪可以完全可以替代5071C，简单易操作，随取随走。维信仪器作为AEM的测试平台，希望大家过来验证测试。
