Component Technology-based Spectrum Analyzer System Software Development

Today, with the rapid development of electronic information technologies, the function of the spectrum analyzer proposed new requirements, but also promoted the development of a spectrum analyzer. The application of software radio technology in the spectrum analyzer promotes the development of spectrum analyzer to digital, intelligent direction, breaks the closed structure of the spectrum analyzer. makes spectrum analyzer with a "software-defined instruments," the feature.The characteristics of spectrum analyzer "software-defined instruments is to make the structure and function of instruments built in an open-style development and use of platforms with a scalable, portable and other features. Developers only need to modify the module function, or develop new modules, you can improve and expand the system's functioning; developers and users only need to functional requirements, system functional modules to be assembled, they meet different application requirements, application development software system flexibility.In this paper, It bring forward a data flow-driven spectrum Analyzer software components frame on technical studies of the concept of data flow and software components, The framework structure greatly increased development efficiency, reduce maintenance costs, enhance the software adaptability. The thesis mainly include:First, It reference data flow-driven system software development research and spectrum analyzer data processing between the various modules of the flow characteristics significantly, then presents a suitable test instrument system software inter-process type variable, block data flow-driven mechanism, And summed up the spectrum analyzer data flow-driven process and the overall structure.Secondly, Through the spectrum analyzer system software requirements analysis, component technology and software design model theory, It proposed a data stream based on the feasibility of instrument software system design, As a basis for the design of a reasonably open level and the size of the instrument software component framework, and application development for the system set to achieve its objectives and technical routes.then, In order to achieve the functions of system software components, spectrum analyzer system software frame design based on functional components of the division of functional components proposed the development of spectrum analyzer model and development process, The instrument function components are designed in detail to determine the standard interface specification.Finally, over on the spectrum analyzer system data flow, software framework and component development model summary, the thesis achieve spectrum analyzer software system software.
