基于虚拟仪器的手机自动测试系统的设计

his paper introduces the characteristic of automatic test system and virtual instrument. The system is then stated in detail from three aspects, which are system flame, hardware construction and software design. Computer can communicate with the instrument with GPIB bus, controlling the instrument based the test sequences which used by people, completing the test data acquisition, processing, and finally displaying the test results. The schemes are consider basing on the current and expansible characteristic. So the system realizes automatism of testing, and it can easily expand and lever up in the same time.
