在雷电远场电磁环境模拟实验中，需要产生一个与雷电波形一致的电磁场。基于LabVIEW 2012软件平台，设计开发了一种雷电波形信号发生器，该信号发生器能够产生国家推荐进行雷电试验的7种用双指数函数拟合的雷电波形和任意实测雷电波形的信号。该信号发生器改善了传统的用模拟电路构建的雷电信号源功能单一和参数调节困难等缺点，在实验中取得了理想的效果。

In the experiment of simulating remote lightning electromagnetic environment,an electromagnetic field accordant with lightning waveform needs to be produced. A lightning waveform signal generator was developed based on LabVIEW2012 software. It can produce seven signals of lightning waveform fitted by double exponential function and measured in any actual measurement,as well as recommended by relevant government department. It also overcame the defects,such as singleness and difficult parameter adjustment of lightning signal source constructed by traditional analogous circuit. This signal generator achieved expecting outcome in the experiment.
