Study Of Multi-function Development & Performance Optimization For Dielectric Spectrum Testing System

With the development of the testing instruments, the requirement of the testing instruments has also been improved. The multifunctional dielectric spectrum testing system has been designed by focusing on high integration, high intelligence and high humanization in this paper. The main research contents are as follows:(1)Optimizing of the dielectric spectroscopy testing system from hardware, software and the connection of the software and hardware. The system has been developed by the function expanded, the compatibility enhanced, the intelligence improved and the man-machine interface perfected. It's better for the industrialization design and the commercialization promotion of the system.(2)Considering that the testing atmosphere will directly affect the defect structure and electrical performance of the materials, a new type of testing system for dielectric temperature characteristic of dielectrics in various atmospheres has been designed and developed. The test system provides the automated measurement of dielectric characteristics with temperature in different atmosphere. The experimental results show that dielectric properties are strongly dependent on the atmospheres. The method provides a simple and effective route for the synthesis of complicated structural defects and polarization mechanism.(3)Based on Visual Basic programming language, a variable temperature frequency spectrum system has been designed, which could reflects the relationship of the electronic material performance and the frequency. The advantages of the system are controllable of the heating process and measurable of the multi-sample. Also the results can be drawn and the data can be dealt with. The experimental results show that the system could reflect the frequency spectrum of the electronic material. The method provides for the research of the electronic material. After further development and optimization of dielectric spectrum testing system, the function has been expanded, the system has been perfected, the appearance has been beautified. In addition to the stability and accuracy of test has been promoted substantially. Now, the device can be successfully complete the automatic measurement of the dielectric spectrum. It is applied in undergraduate program and postgraduate research work. Also it gets a better evaluation by providing testing services in number of other universities and research institutes.
