Research And Implementation Of Wideband High Resolution Frequency Synthesizer

With the development of computer network information technology,the field of testing is also constantly moving towards digitization and networking.While the test system realizes remote testing,diagnosis and information sharing,it is a test system in a distributed network environment to effectively respond to the increasingly complex objects to be tested,increasingly rich test products,more varied test requirements,and larger test data.The main problems faced.A new set of distributed software system construction methods and environments: Service-Oriented Architecture(SOA)has a unified set of standards.The standard allows a high degree of information sharing and does not depend on specific technologies or specific platforms.There is a high degree of decoupling between the requester and the provider.This loosely coupled system allows the software to flexibly adapt to changes in business requirements and is highly reusable.The application of SOA in the field of automatic testing can effectively solve the problems facing the field of testing.This paper focuses on the research of service composition and invocation of distributed test system based on SOA.Through studying and researching SOA technology,Web service composition technology,workflow technology,and interface development of system software composition services,we have implemented a set of ground maintenance System testing software.The test system can meet more test needs of customers through the combined call of test services.In order to realize the function of this system,the main work content is:(1)Analyze the functional requirements of the system software platform,fully consider the scalability and fault tolerance of the ground maintenance system software,and propose a design plan for the ground maintenance system software.(2)To provide distributed test equipment with browser access,complete the integration of the service call interface of the distributed test equipment,and combine these services into processes to form a variety of new services to meet the needs of test users.To this end,the relevant knowledge and technology of service process combination are researched,service combination software is deployed for the system,for the user terminal to build and run the test service in the browser mode,and the test results are stored in the local data center,and the data and The status of the test process is presented to the user terminal.At the same time,in order to facilitate user operation,the system provides a simple and easy-to-use front-end page for customers to use.(3)The data collection of the test system is very important.Faced with more and more test data,faced with the user's functional requirements and performance and capacity development requirements,faced with the system's ability to collect data in real time,the ELK solution was studied.The service-oriented system was tested.The test results show that the system has the function of testing service process combination and invocation,and under high request count and high concurrent access,the test system has no abnormalities or even crashes,indicating that the system has a large number of When users access at the same time,they have a strong load capacity,the system is stable and available,and its performance can meet the needs.
