OPEN ALLIANCE TC2和TC9線束以太網(wǎng)測(cè)試標(biāo)準(zhǔn)？

聯(lián)盟中TC2汽車(chē)線束以太網(wǎng)線束定義標(biāo)準(zhǔn)：

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(lián)盟中TC9汽車(chē)線束以太網(wǎng)線束定義標(biāo)準(zhǔn)：

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(guò)OPEN聯(lián)盟這兩個(gè)協(xié)議標(biāo)準(zhǔn)來(lái)看，TC2就是100M,TC9就是1000M.除了常規(guī)使用KEYSIGHT的5071C等RF矢量網(wǎng)絡(luò)分析儀可以做。目前還有哪些設(shè)備可以滿(mǎn)足此項(xiàng)測(cè)試要求呢？
以上是實(shí)驗(yàn)室常規(guī)測(cè)試方法：

通過(guò)治具嚴(yán)格按照測(cè)試標(biāo)準(zhǔn)的方法一步步進(jìn)行測(cè)試。其步驟比較繁瑣，一步錯(cuò)，就不能保準(zhǔn)數(shù)據(jù)的準(zhǔn)確性。

目前有一種可替代的測(cè)試設(shè)備，簡(jiǎn)單易操作。

一步到位可以測(cè)試出所有的線束標(biāo)準(zhǔn)中需要的參數(shù)。

總之，隨科學(xué)技術(shù)的發(fā)展，我們的選擇行很高，不簡(jiǎn)單的局限于傳統(tǒng)的繁瑣的測(cè)試方法以及步驟。AEM線束測(cè)試儀可以完全可以替代5071C，簡(jiǎn)單易操作，隨取隨走。維信儀器作為AEM的測(cè)試平臺(tái)，希望大家過(guò)來(lái)驗(yàn)證測(cè)試。
