Abstract

An oscilloscope is a fundamental device in electrical engineering. With an oscilloscope we can view the electrical signal in real time to help us find possible glitches in the electrical circuit. This dissertation starts off with a presentation of what an oscilloscope is. The basic terminology of oscilloscopes is introduced in this part along with an explanation of how an oscilloscope works. In the second part we create a simple digital oscilloscope, which can capture the signal and display it to the screen of a PC. For this purpose, we use a development board STM32F4-Discovery, which can be acquired at a reasonable price. We use it to detect a digital event on the signal and then capture it. Captured samples are transferred to a PC using USB protocol and are displayed to the screen. We test our digital oscilloscope by capturing PWM and RS232 signals.
