一、引言许多系统和设备在工作前后,需要加上各种标准波形作为激励信号,检查系统和设备是否工作正常,以确保系统现状可靠。但是在自动快速测试系统中,要求的激励源是多种多样的,因而要求有一个能在程序控制下快速改变波形的通用信号源。本文所描述的可编程任意波形发生器就是产生这类标准信号的装置。 I. INTRODUCTION Many systems and equipment need to add various standard waveforms as excitation signal before and after their work to check whether the system and equipment are working properly to ensure the system is in a reliable condition. However, in automated rapid test systems, the required sources of excitation are varied and require a universal source that can quickly change the waveform under program control. The programmable arbitrary waveform generator described in this article is the device that produces such a standard signal.
