实在抱歉，这个要使用 WAVEFORM 里面的user defined.不过本人也没用过，在手册里面也没提到，还请高手出手了。 Jt5\  
    请问为什么要使用方波呢?

我看到有一篇研究关于平行微带线的串扰文章中，激励源加的是方波。在方波的上升和下降期，受干扰的线上会产生一个很窄的方波。所以我想加个方波试试看。user defined只能从外部导入已经自定义的波形文件，现在我就是不知道怎么编辑.src的文件。

user defined从外部导入已经自定义的波形文件，强行定义一个后缀为.src的文件，用记事本可以打开，将matlab等生成的数据拷贝到.src文件中，再用USER DEFINED 进行导入即可 FR*CiaD1  

我也想知道

波形文件需要matlab等生成吗

能说清楚点吗，我也想知道

我也是为此目的而注册的！说清楚点

英文版的使用手册看的头痛！

an integer, which is the number of time steps in the waveform; additional time steps will =vs]Kmm  
be zero-padded. The format of the rest of the file depends upon whether a voltage @=ro/.
