This research aims to design an Arduino-based SI5351 Signal Generator with a 225 MHz output, intended to serve as a laboratory practicum assistance tool at Surabaya Aviation Polytechnic. The current signal generator used in the laboratory provides limited waveform shapes and a restricted frequency range, which hampers students' understanding and exploration of signal generators during their practical sessions.
To address this issue, the research employs the research and development (R&D) method, utilizing the 4D development model, which consists of the Define, Design, Develop, and Disseminate phases. The primary goal of this method is to create a product that offers three types of output signals: sine, square, and triangle waves, all operating at a frequency of 225 MHz.
The final design of the SI5351 Signal Generator will provide students with a more comprehensive and versatile learning experience, enabling them to grasp the concepts and applications of signal generators effectively during their laboratory practicums.
