摘　　要：针对加载板传输速率校准测试要求,开发了一种基于LAN接口组合仪器自动测试平台,该平台基于虚拟仪器技术中的LabVIEW图形化编程开发,将多台仪器有机组合. 并采用眼图六点法检测的方式,将预估眼图面积与理想状态的眼图面积之比与阈值比较,通过这种方法对信号的传输速率质量进行评判,实现了对加载板传输速率校准的自动有序测试,自动存储,对加载板传输速率生产检验具有重大的实际工程意义.In order to test the transfer rate of loading plate, a LAN interface independent instrument integration testing platform was developed. The development of this platform is based on virtual instrument technology in LabVIEW graphical programming environment. It＇s the organic integration of multiple instruments. Eye diagram six point method detection was used to get the ratio of the estimated eye diagram area and the ideal eye diagram area. Then the ratio was compared with the threshold value. This approach is used to judge the quality of the transmission rate of the signal and has achieved a ordered automatic calibration tests of transmission rate of the loading plate and automatic storage. The transmission rate of loading plate production inspection is of great practical significance.
