摘要
针对集成运算放大器测试平台通用性和可扩展性不足的问题,基于虚拟仪器技术提出涵盖芯片交直流指标测试的自动测试系统实验方案。按照测试规范,用Multisim软件进行测量电路仿真和数值参数计算,设计和搭建实际电路,结合ELVIS Ⅲ实验测试平台使用LabVIEW开发上位机功能软件,完成信号驱动、实验调试、实时测量和数据分析的一体化集成测试。仿真结果和实测效果表明,该实验方案可提高参数测试的完备性、灵活性和测试效率,有利于学生参与自主设计,培养综合素质和创新能力。
To overcome the lack of versatility and scalability of the integrated operational amplifier test platform, a computer based automatic test system scheme covering chip AC/DC characteristics is proposed with the aid of virtual instrument technology. According to the test standard, measurement circuit simulation and numerical parameters calculation are implemented with Multisim software firstly, and then the physical circuit is designed and built for test interface hardware. Finally, combined with semiconductor ELVIS Ⅲ platform, LabVIEW is used to develop PC application software, and then to complete the integration of signal driving, experimental debugging, real-time measurement and data analysis. The simulation and test results show that it can improve the universality, flexibility and efficiency, and cultivate students’ innovative ability of theory and practice.
