OPEN ALLIANCE TC2和TC9線束以太網測試標準？
聯盟中TC2汽車線束以太網線束定義標準：
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.
聯盟中TC9汽車線束以太網線束定義標準：
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
通過OPEN聯盟這兩個協議標準來看，TC2就是100M,TC9就是1000M.除了常規使用KEYSIGHT的5071C等RF矢量網絡分析儀可以做。目前還有哪些設備可以滿足此項測試要求呢？
以上是實驗室常規測試方法：
通過治具嚴格按照測試標準的方法一步步進行測試。其步驟比較繁瑣，一步錯，就不能保準數據的準確性。
目前有一種可替代的測試設備，簡單易操作。
一步到位可以測試出所有的線束標準中需要的參數。
總之，隨科學技術的發展，我們的選擇行很高，不簡單的局限于傳統的繁瑣的測試方法以及步驟。AEM線束測試儀可以可以替代5071C，簡單易操作，隨取隨走。維信儀器作為AEM的測試平臺，希望大家過來驗證測試。
