A Spectrum Analyzer is an instrumentation device capable of displaying and analyzing signal frequencies. This tool is crucial, but in practice, it comes with a high price tag, making it inaccessible to many individuals. One way to overcome this challenge is by creating something that can provide functionality similar to a spectrum analyzer at a relatively affordable cost. This way, it can be implemented and expected to serve as a tool to enhance the quality of learning. The research utilizes the research and development (R&D) method with the ADDIE development model. Additionally, this study employs RTL – SDR to process signals received by the antenna. The research process involves the use in Python programming language, which is then connected to RTL – SDR to generate signals. The spectrum produced by the system constructed with the factory-produced spectrum analyzer shows that obtained frequencies are well-receivedd in each respective spectrum. During the testing phase, we distributed a validity questionnaire covering various assessment aspects. The results showed an 86% suitability rating for the applications’s performance, equipment functionality and application design. Based on the validation results, it can be concluded that the design is suitable for use
