【摘要】 针对电路板级测试,由于其功能的不完整性和信号的不规则性,直接搭建测试系统比较困难,文章采用和单板进行配合的辅助电路模块,提出了“功能产品”的概念,实现在其功能产品级工作状态下测量的方法,利用成熟的高速PCI总线技术和DSP技术,对其功能进行测试和利用IVI技术构成的虚拟仪器系统,对其控制信号进行测试。实现了信号的同步采集、分析、给出测试结论,具有一定的参考价值。更多还原

【Abstract】 For the non-integrality function and irregulation signal of the sect circuit, It is more difficult to directly constitute the testing system.A concept of Function product is put forward, taking advantage of high-speed PCI Bus、DSP and IVI virtual instrument technologies. A accessorial circuit module is built up which cooperates with the sect circuit, and a valuable function-test design in product-level is realized.更多还原
