Abstract

Virtual Oscilloscope features the interface of actual oscilloscope, with conventional gain, offset, timebase, and trigger controls. The scale and position for each channel of virtual oscilloscope is adjustable as is the time base. The trigger source and mode can also be set. All of the functions are similar to a standard laboratory oscilloscope. This project uses National Instrument LabVIEW 7.0 where Lab VIEW is a graphical programming language that uses icons instead of lines of text to create applications. Virtual Oscilloscope was integrated with NI USB-6009 device where this device has the ability to perform many different functions. The NI USB-6009 provides connection to eight analog input (AI) channels, two analog output (AO) channels, 12 digital input/output (DIO) channels, and a 32-bit counter with a full-speed USB interface. This oscilloscope have two channels, voltage sensitivity 0.1 V/Div - 5V/Div in 6 steps, time sensitivity 1 miliseconds/Div - 10 miliseconds/Div in 4 steps. The main goal of this project is to develop oscilloscope that convert personal computer into virtual instrument. In other words, user can directly use a personal computer with Virtual Oscilloscope software installed and integrated with NI USB 6009, and also with signal introduced from function generator. One of the major advantages of this virtual oscilloscope project is the ability to see inside the instrument and to understand how it works. By developing this project, the cost of oscilloscope will be less expensive and the data can be analyzed simply and in more detail.
