Design And Implementation Of Universal RF Test System Based On VB.NET

In recent years,the development of mobile communication network is developing rapidly.The devices updating is faster and faster,and the cost is rapidly reduced.As a key step of communication product R&D and production,product testing is facing new challenges as well.Traditional testing software has a long development time,poor compatibility of instrument and equipment,and incompatible software of different products,wasted lots of resources.With the development of automation technology and software engineering,RF automatic test system update ushered in new opportunities.This paper takes modern software engineering as the research method,analyzes the content and process of RF communication product testing work,and analyzes and models the requirements according to the actual status and needs of the enterprise production line.In the software implementation part,VB.Net,an object-oriented programming language,was selected as the development tool.Finally,a modular universal automated RF test system was designed and developed.The system software part contains multiple functional modules.Each module uses a separate project for code development;and uses the methods of inheritance and interfaces in the object-oriented language to complete the code implementation of the abstract model;and finally use.Net method encapsulates each module into a separate component(Assembly),which is combined with the corresponding RF test equipment to form a complete RF automatic test system.The RF test system not only achieves the basic functions of automatic testing of products and records test results,but also realizes the generalization of multi-product test platforms,the generalization of test tasks,and the generalization of instrumentation;the rapid development of test procedures and the shortening of new ones.The cycle of product delivery and production;the rapid deployment and maintenance of the RF test system in the actual production test machine.Help the production department to achieve capacity improvement,personnel streamlining,effective use of different types of instruments,multi-product testing software compatibility,etc.,effectively improve efficiency and reduce costs from both R&D and production,helping enterprises to occupy a favorable position in the market competition.
