碩士 === 大葉大學 === 電信工程學系碩士班 === 92 === In this thesis, it focuses on the measurement system of components and products for communication. We explore the quality and requirement of components and products, and actually provide the test system of components and products built by us. At first, this thesis would introduce the smart antenna test bed which were designed and built by ourselves. It includes the quality and advantages of smart antenna system, the idea of design to the smart antenna test bed, the method we used in hardware and software, and the discussion of the theory for test bed. Then we would use the smart antenna test bed to test kinds of antenna designed by our laboratory and to verify smart antenna test bed. In the following, this thesis introduces the pager measurement system which assisted UNICATION GROUP in design. It focuses the test of whole product, and it would introduce the method which used in hardware and the test environment of pager measurement system. It would discuss the purpose and method of software for each test item; then, test and verify for the products. At last, pager measurement system would test the products in the micro-wave chamber to isolate the interference when comparing the sensitivity to each angle; and then, we use the salt solution to fill pillar to simulate the pager with human body to test the sensitivity. And the influences of different test results are discussed in this thesis.
