| 摘 要： | 简要介绍一个针对多路谱仪放大器的读出与数据采集方法与系统.该系统基于16通道门积分/选通输出电路和通用PⅪ-AQ卡构建.利用Lab Windows/CⅥ平台构建虚拟仪器,灵活地将计算机、硬件、软件结合起来,设计了一个读出与数据采集系统.在该系统中,一个ADC通道可以面对16个谱仪放大器的输出,有效地提高了系统的集成度,降低了数据采集系统的成本.该设计为利用通用型谱仪放大器构建数百参数的信号读出与数据采集系统提供了一种新的方法.通过实验验证,证明该系统具有智能化、可靠性高、实时性强、成本低等优点.

| Abstract: | A read-out and data acquisition system for the outputs of multi-channel spectroscopy amplifiers is introduced briefly in this paper.The 16-channel gating integrator/multiplexer developed by us and PXI-DAQ card are used to construct this system.A virtual instrument system for displaying,indicating,measuring and recording of output waveform is accomplished by integrating the PC,hardware,software together flexibly based on the Lab Windows/CVI platform in our read-out and data acquisition system.In this system,... |
