摘要
利用PC机和基于PCI总线的高速数据采集卡PCI-1711,开发出了新型PTCR伏安特性测试系统。利用采集卡的数字量输出与模拟量输入功能,配以外围接口电路,有效地实现了对电路的控制和对所需数据的采集,同时能对十工位PTCR的伏安特性进行测量。还介绍了时分复用技术在测试系统中的应用。
By using computer and high-speed data acquisition card PCI - 1711 which is based on the PCI bus, a new model of measuring system for PTCR＇ s volt-ampere characteristic was built up. Taking use of the card＇s DO/AI function and through the peripheral interface circuit, circuit controlling and data acquisition can be achieved simply and effectively. The application of time division multiplexing in this system was also introduced.
