摘要
为了获得测试测量中特殊信号的波形,在上位机波形编辑软件和信号发生器基础上,提出了任意信号发生器的设计方法。在MFC平台上,实现任意波形编辑软件。该软件支持手绘任意波形、高阶曲线拟合以及常用波形编辑,并可将波形数据下载至基于C8051F340单片机的信号发生器中。实验表明,本设计方案可以获得任意手绘波形、高阶拟合曲线波形、正弦波、可调占空比的三角波和方波、高斯噪声等,还实现了多通道输出和通道间有幅度或者相位关联输出,具有实际应用价值。
in order to obtain the special waveforms used in test and measurement, a method to design arbitrary wavefmxn generator（AWG） is proposed based on the waveform editing software in the PC and the signal gener- ator. The waveform editing software is designed by using VC 6.0 MFC programming, which supports any hand- drawn waveforms, high order curve fitting waveforms, and common waveform output. The waveform data can be downloaded to the AWG based on C8051 F340 MCU. Experiments show that any hand-drawn waveforms, high order curve fitting waveforms, sine, triangular or square waveform with variable duty cycle and Gaussian noise are obtained. Besides, the AWG can output mufti-channel＇ s waveforms that are completely different or waveforms with relative phases or different amplitudes. Results show that this design has practical value.
