Qscilloscope: A PC-based Real Time Oscilloscope

The scenery of this paper is to design a PC-based Real Time Oscilloscope, called dasiaQscilloscopepsila. Qscilloscope is capable to connect a computer with a small device via universal serial bus (USB) port for voltage signal waveform display and alteration. It detects maximum +20V to minimum -20V with the input frequency range from 0.1Hz - 1 kHz. Furthermore, it interfaces with host PC via the USB port from 9.6k to 115.2k baud rate. Qscilloscope Software Application is constructed by using Visual Basic .Net for user to interface the device with a well designed Graphic User Interface. It consists of several embedded features such as open, save and print waveform. By changing the scaling properties and graphic properties, users are allowed to modify the input signal to a desired output waveform.
