摘　　要：文章介绍了基于LabVIEW的卫星数字电视接收机视频指标的自动测试系统,该系统是通过GPIB总线将PC和视频分析仪连接起来,利用LabVIEW图形化的编程方法,实现了仪器的自动测量,同时将测量结果传入电脑,最后通过数据读取程序,自动生成所需的测试报告。实验表明,利用该方法不仅提高了测试效率,而且可以增加测试可信度,降低人为错误。In the paper,it is introduced a kind of automatic test system with video index in satellite digital television receiver based on LabVIEW.This system makes PC connect with video analyzer by GPIB bus.It makes use of programme with LabVIEW graphics to realize instrumental measurement automatically.At the same time,it could introduce the measure result into computer,and read programme through data to create test record which was needed finally.Experiment makes show that this way not only improve test efficiency,but also increase test reliability,and reduce the contrived error.
