Personal computer based oscilloscope

Abstract

This research is focusing on how to build a PC based oscilloscope. The aim of this project is to produce the low cost of oscilloscope and easily oscilloscope. PC based oscilloscope is developed using the combination of hardware and software designs. The hardware design like analog circuit is used to produce the output voltage in the range of OV to 5V. The analogue circuit, firstly is created using Multisim software and then is converted to the breadboard with real components. The Motorola 68000 microprocessor training system consist of analog to digital converter and dual universal asynchronous receiver/transmitter (DUART) integrated circuit (IC) which can be used to convert the analog circuit to digital and send the data to personal computer (PC). The digital input is in hexadecimal number. The Visual Basic 6.0 software is very important to design oscilloscope. This project will be completed when the PC base oscilloscope can be stand alone.
