摘　　要：设计了一个多路模拟数据采集与控制测试平台,通过USB-6211数据采集卡结合LabVIEW软件进行设计,实现了多路模拟信号采集和多路数字信号输出的功能。通过对采集后信号的拆分,对每个通道数据进行分析、处理。以模拟电子技术中共射极单管放大电路作为测试对象,对系统进行验证,整个系统运行状态良好,系统具有一定的通用性和可移植性。A multi-channel data acquisition and digital control function was achieved, and a multi-channel data acquisition system based on LabVIEW was designed to complete data acquisition by USB-6211 data acquisition card. The total signal was decomposed data of each channel,which was analyzed and processed. The common emitter single transistor amplifier circuit in analog electronics technology was used as the test object to verify the system. It is proved that the function for the analog voltage signals acquisition is good, the system has certain versatility and portability.
