Comparison of a designed virtual oscilloscope with a real oscilloscope

摘要

A virtual oscilloscope based on Lab VIEW software was designed. Sinus, square and triangle shaped signals produced by a function generator were analyzed with a real and a virtual oscilloscope. Amplitude, rise time and fall time values of a signal were determined for different time/division values in both type oscilloscopes. Obtained values in the virtual oscilloscope were compared with those of the real oscilloscope. It was deduced from the results that amplitude, rise time and fall time values and signal shapes were compatible with each other.
