摘要: 为方便快速地评估和选择一种用于ITER( International Theramonuclear Experimental Reactor) 软X 射线诊断的信号远传雷莫连接器,基于三维电磁仿真软件CST( Computer Simulation Technology) 建立了雷莫公司一款连接器( 插座ECG. 3B. 332. CLV 和插头FGG. 3B. 332. CLAD12) 的三维模型。仿真并分析了此款雷莫连接器的传输延时、散射参数( Scatter 参数) 、针芯拐角值及串扰等参数对传输信号完整性的影响,并与频谱分析仪等设备对连接器的传输信号串扰测试结果进行比较分析。仿真结果表明,在连接器的工作频带内,插入损耗不低于- 0. 5 dB,针芯的拐角值对应的插入损耗、回波损耗均与频率存在指数关系,串扰幅值与频率具有二次函数关系。仿真结果与串扰测试结果具有较好的一致性。后续等离子体诊断环境中其他诊断信号连接器也可通过此仿真方法进行测试和可靠性评估。

Abstract: To evaluate and select a signal remote Remo ( LEMO ) connector for ITER ( International Theramonuclear Experimental Reactor) soft X-ray diagnosis conveniently and quickly,based on the threedimensional electromagnetic simulation software CST ( Computer Simulation Technology) ,a three-dimensional model of a connector ( socket ECG. 3B. 332. CLV and plug FGG. 3B. 332. CLAD12) is established. The effects of transmission delay,scatter parameter,pin core corner value and crosstalk on transmission signal integrity are simulated and analyzed,and compared with the test results of the crosstalk of the transmission signal of the connectors by spectrum analyzer and other devices. The simulation results show that the insertion loss is not less than - 0. 5 dB. The insertion loss and return loss corresponding to the corner value of the pin core have exponential relationship with the frequency,and the crosstalk amplitude has quadratic function relationship with the frequency in the working frequency band of the Remo connector. The simulation results are in good
agreement with the crosstalk test results. The simulation method and research findings can be used to test and evaluate the reliability of other diagnostic signal connectors in the subsequent plasma diagnostic environment.

Key words: connector, crosstalk, Scatter parameter, delay, corner, computer simulation technology ( CST)
