一种新的任意可编辑合成信号源的设计

A New Signal Generator Design with Editorial Compound

汽车行业的EMC测试中频繁需要各种形式的信号源,传统信号发生器只能产生正弦、方波、三角波和锯齿波四种标准波,笔者在此基础上,开发了一种新的基于LabVIEW的任意可编辑合成信号发生器。该发生器利用类MATLAB Simulink库的Simulation Interface Toolkit工具包生成扫频波;通过镜像,叠加,光标获取等操作实现任意波的合成;并能指定任意子波段进行编辑,实时更新数据库。功能上大大扩展了传统信号源发生器,且成本低廉,在EMC测试部门得到了很好地应用。

Various signals need to be used in auto's EMC test.Since the traditional signal generator can only generate waves of sine,square,triangle and sawtooth,we developed a new signal generator based on the virtual instrument which can generate ehirpwave by Simulation Interface Toolkit.It can use mapping,superposition and cursor acquisition to generate a new editorial compound waveform,and it can edit its sub-waves and update database real time. With multi-functions and low cost,it applies well in the EMC test department.
