摘　　要：本文提出了一种基于虚拟仪器的雷达发射机自动测试系统的研究方案,将虚拟仪器的概念应用到标准仪器的测量控制系统中,通过编程语言LabWindows/CVI对标准仪器进行控制。该测控系统采用基于GPIB卡的主从式分布结构。在测控过程中,工控机平台成为控制环节的主节点,通过GPIB电缆连接微波信号源、脉冲信号源、数字示波器、峰值功率计4台标准仪器来进行整个系统的数据信息传递,完成发射机导引头各参数的实时采集、选择性存储、波形打印。A research scheme of Automatic Testing System for radar transmitter based On virtual instrument technique is presented in this paper. The virtual instrument technique is applied into the instrument control system, and standard instrument is controlled with the programming language LabWindows/CVI in ATS. This ATS adopts master-slaves distributed structure based on GPIB card. During the measurement and control process, the industrial control computer platform is the key point in the overall controlling system, and the data information is transmitted between the industrial control computer and instruments such as microwave signal source, pulse signal source, digital oscilloscope and peak power meter by GPIB cables. Meanwhile, every parameter is collected in real-time, selectively saved and printed.
