Abstract

Spectrum analyzer is a device used to measure the frequency of a signal but is a device that has a steep price on the market. To help reducing the cost of making a spectrum analyzer, a Raspberry Pi, which is known as a cheap small computer used for many projects can be used to make a portable spectrum analyzer. The objective of the project is to develop a radio spectrum analyzer using a Raspberry Pi and RTL-SDR. This project will use only 5v power supply to power it. An external battery bank can be used to power the project on the go. This characteristic makes this project an energy efficient and mobile solution. This project is targeted to be used as a teaching tool for secondary school student. The result as expected is to have a fully functional and widely documented portable spectrum analyzer done by using cheap and efficient solution.
