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

  聯(lián)盟中TC2汽車線束以太網(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OPEN聯(lián)盟這兩個(gè)協(xié)議標(biāo)準(zhǔn)來看,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)備可以滿足此項(xiàng)測試要求呢?

  以上是實(shí)驗(yàn)室常規(guī)測試方法:

  通過治具嚴(yán)格按照測試標(biāo)準(zhǔn)的方法一步步進(jìn)行測試。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試設(shè)備,簡單易操作。

  一步到位可以測試出所有的線束標(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,不簡單的局限于傳統(tǒng)的繁瑣的測試方法以及步驟。AEM線束測試儀可以完全可以替代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(yàn)證測試。
