Es4541 Logic Analyzer System Software Design

In this dissertation, first, based on the aspects of the request to the instrument in data domain test logic analyzer's development and it's architecture are introduced. And the principle of virtual logic analyzer is discussed. Second, object-oriented programming and windows programming is introduced. The design of the control function and the GPIB communication of system software. At last the dissertation deals with the debugging of the system program.Chapter one discusses the signal characteristic and detecting requirement of digital system, and introduces the application in data domain test, the development of logic analyzer and the system architecture. The principle of the ES4541 logic analyzer is also introduced in this chapter. Chapter two discusses the object-oriented programming method ? the knowledge in windows programming which are applied in system software design of logic analyzer and the interface between the users and the computers. Then it introduces the used programming software桞orland C++ Builder. Chapter three discusses aspects of software design of ES4541 logic analyzer including the system structure, the system function, the user-defined class, the programming of waveform analysis and displaying. It elaborates the realization of the storing and the opening of waveform, the realization of the pre-defined word trigging and the document of system software. Chapter four detailly discusses the GPIB's control programming. Chapter five introduces the debugging environment and method of C++ Builder and introduces the system software's debugging and error correcting.
