CST MWS如何导入外部激励源

请学会使用软件的帮助文件。
CST MWS帮助文件《Excitation Functions》：
Import: Enables you to import a two-column table from an ASCII file which contains the time and signal data. Please note that the data of an imported signal is always interpreted in the unit seconds.

我最后弄好了，因为我在第一行加了Time这个标注，所以就不行，我给删啦，然后就行啦
