摘要
为满足工程系统综合试验对特殊不规则波形信号的需求,设计开发了一款基于PXI-6713模块的多功能形信号发生平台。以计算机作为统一的硬件平台,充分利用计算机强大的软件功能完成了信号由数字量向模拟量的最终转换输出。相比传统硬件仪器,该虚拟仪器平台操作简单,可扩展空间大,不仅能够实现多个通道同时输出三角、正弦、方波等规则的周期信号,更可以满足同步输出用户自定义的任意波形信号的要求。
Considering the requirement of special irregular waveforms in engineering system comprehensive tests,a multi-function signal generator based on PXI-6713 has been designed and developed.With a computer as the uniform hardware platform,it makes full use of powerful software function to have achieved the conversion and output of the signal from digital to analog.Compared with traditional hardware instruments,such a virtual platform is much easier at operation,and has greater scalability room.It can realise multi-channel simultaneous output of regular periodic signals including triangle,sine and square wave,etc.,and can also meet the requirement of synchronise outputs of user-defined arbitrary waveform signals.
