摘　　要：对基于PXI总线的A/D数据采集电路进行了结构划分、设计和实现。该数据采集模块主要通过PCI9052桥芯片将ISA插卡信号移植到CPCI总线上,作为PXI测试系统的一个功能模块,通过CPLD实时响应零槽控制器发出的触发信号。The article introduces PXI bus which is widely applied in the test system firstly,then makes module division,design and implemention for A/D data acquisition circuit based on PXI bus. The module of A/D data acquisition mainly plants the signals from ISA bus to CPCI bus,and becomes an important module of PXI test system via PCI9052 chip,and responds real-time trigger signals which are generated by zero pocket controller with the help of CPLD.
