本文论述的是一个基于 VXI 总线仪器的先进的电路印制板(PCB)自动测试与故障诊断系统,与其它夹具式电路板在线测试仪所不同之处在于它既可对被测电路板进行整体功能测试,又可对单个器件进行在线测试,在对单个器件进行在线测试时无需对被测器件施加任何激励或设保护点。实践证明该系统的测试方法先进,故障定位准确。 This article discusses an advanced circuit board (PCB) automatic test and fault diagnosis system based on the VXI bus instrument, which differs from other on-board tester circuits in terms of both the board being tested Functional test, but also on-line test of a single device, in the on-line test of a single device without the need to exert any incentives on the device under test or set the protection point. Practice has proved that the system of advanced testing methods, fault location accurate.
