摘要
线缆在实际工作时通常面临的是多源干扰,论文利用CST软件的电缆求解模块,对线缆一端分别注入单源和双源时的辐射发射和串扰进行了仿真,获得了辐射发射频谱、感应电流波形,为多源同时注入电子设备时的辐射发射和串扰分析奠定了基础。通过仿真计算,得出在正弦信号注入时的辐射峰值为21.6 dBuV/m/5MHz,在三角脉冲信号注入时的辐射峰值为17.9 dBuV/m/20MHz。两种信号同时注入时,辐射峰值分别减少为15.8 dBuV/m/5MHz、12.8 dBuV/m/20MHz,相邻同轴线缆近端的串扰感应电流幅值为15uA。
It is often presented with multi-source interference for cables in practice. In this paper,based on the cable studio of CST software,the radiation emission and cross talk of cables are simulated with single source and double sources injected to the input port,respectively. Radiation spectrum and inducted current waveform are obtained,which build a foundation for radiation emission and cross talk analysis of electronic equipments with multi-sources injected. The simulated radiation peak values are 21.6 dBuV/m/5MHz with sinusoidal signal injected and 17.9 dBuV/m/20 MHz with triangular pulse signal injected. The peak values are reduced to 15.8 dBuV/m/5MHz and 12.8 dBuV/m/20 MHz with two types of sources injected simultaneously,and the induced current of cross talk for adjacent coaxial cable at the near-end is 15 uA.
