本软件实现了示波器，信号发生器，频率计，万用表的功能，在音频范围内可完全替代上述仪器。这并不是仿真软件，而是实用的工具，这些虚拟仪器可以很好的工作。最简单的应用只需要两根电缆，一根输入，一根输出。-this software realize the function of oscillograph and signal befallen and cymometer and multimeter. in frequency confine can substitute for instrument so you say,this software is not a emulational software but a applied tool.these dummy instrument can do well many job.the simple application mere need two cable ,one input,the other output.
