High-precision automated testing system for wireless sensor network IC

This paper introduces a high precision automated test system. We built an automated testing platform using programmable test equipments and designed a series of test boards to adapt the test process. Combined virtual instrument technology and software radio technology, we realized to test the wireless sensor network IC automatically. Compared with other test system, this system has the advantages of high precision, high degree of automation and strong portability etc. It's fast and convenient to change test function and has a lowest cost of long-term use. This system can be used in the laboratory test and small batch automated test system, and also can be applied to large quantities of chip test production line.
