混杂型高速数据传输线缆性能测试

摘要

在LHC ATLAS实验Phase-I升级中，需要同时具有耐辐照、超细及高速传输能力的电子数据传输线。针对美国加利福利亚大学给出的混杂型高速电子数据传输线缆，设计了测试方法和方案，通过不同编码下通信速率测试、TID测试、眼图测试获得线缆通信性能数据，表明此线缆具有高速数据传输能力，旨在为线缆设计和选择提供支持。%The super-fine,radiation-resistant and high-speed electronic data transmission cable is needed in the LHC ATLAS experiment Phase-I upgrade. Hybrid cable scheme of constructed by One meter TWP and six meters Twinax Cable proposed by University of California is introduced. Test and calibration scheme are proposed for the hybrid cable. The data communication rate test,TID test and Eye diagram under different coding and signal fashions are applied into the hybrid cable measurement in order to obtain its performance. The test result shows high-speed data can be transferred by the hybrid cable and the scheme can guide cable design and selection.
