Research on General Test System Based on VI Technique and Boundary Scan Technique for Electrical Modules

In order to test military electrical modules effectively, according to the feature of small batch and varied type, the proper testing strategy is designed. The VI and boundary scan technique is applied, an automated general test system based on PXI test bus is established, the functional test and structural test is realized. The test system can test varied electrical modules, so it plays an important role in improving fault positioning and reducing the testing time. The test system meets the requirements of production test and maintenance test effectively.
