| Abstract: | In-Circuit Test is widely used in electronics device performance test and fault diagnosis. The paper designs a circuit board fault testing system based on Analog Signature Analysis technology of In-Circuit Test. The testing system adopts advanced NI data acquisition card, combining with the periphery signal acquisition circuit and the upper software design, which can effectively detect cir- cuit fault. Compared to traditional Analog Signature Analysis testing system, our design has the ad- vantage of simple realization, stable operation and strong configurable ability. |
