摘要:
高速电路板的上升时间是衡量其性能优劣的一个重要参数,测量上升时间需要使用多台不同性质的仪器,才能完成信号的发送、数据采集、数据存储、分析波形等任务,采用传统人工控制仪器和手工抄录数据的方式,工作质量和工作效率不高,容易受人为因素影响,造成测试过程难于准确控制. 为此针对高速电路板上升时间的测试,设计了一套自动测试系统. 采用基于虚拟仪器的技术,通过通用接口总线实现PC机与可编程仪器之间的通信,使用图形化编程语言LabVIEW完成测试软件的编译,从而实现测试仪器的有序控制的目的. 在测试过程中,测试数据实时显示在测试软件的控制界面中;同时将采集的测试数据实时保存在数据库中,以供后续分析使用,扩展了测试仪器的功能.
Abstract:
High-speed circuit board has been widely applied in various electronic equipment, the rise time of which is an important parameter to measure its performance. To measure the rise time of High-speed circuit board, multiple types of instruments were used to accomplish series of tasks, including signal sending, date recording, date storing and analyzing. The traditional measuring method adopts manual control instrument to transcribe data, which resulted in low quality and inefficiency and is affected easily by artificial factors. As a consequence, the testing process is difficult to control accurately. Therefore, we designed an automatic test system for measuring the rise time of high-speed circuit board. Based on virtual instrument technology, general-purpose interface bus was used to realize the data communication between the programmable instrument and personal computer. Then, the testing software was compiled by graphical programming language of LabVIEW. Finally, the purpose of designing a controllable automatic test system was achieved. In the process of testing, test data display in the control interface of the testing software. Meanwhile, the testing results are saved in database for the later analysis,thus the functions of testing instrument are greatly extended.
