Multi-user spectrum analyzer using Java-based client-server application

Spectrum analyzer is used to support laboratory activity for students, and also used by company providing telecommunication service and government agencies to monitor frequency utilization. Today, the price of spectrum analyzer is relatively expensive, leading universities and companies in need of such tools are generally able to provide in a limited amount. Based on these problems, the authors propose a client-server application that allows multiple users to simultaneously visualize measurements made by spectrum analyzer in real time with different parameters. This application is implemented in Java programming language that can be used in a wide range of platforms. After implementation and testing, this application can be used by more than one client at the same time and by using different parameters. Thus, this application can minimize the amount of spectrum analyzer required. In addition, this application also provides several other advantages, such as remote use, minimize maintenance costs and extend the lifetime of the gauge.
