What is an oscilloscope used for?
• Measuring time-varying signals – by showing details of the waveshape • Measuring aspects of time-varying signals • Frequency of a signal • Peak value of a signal The oscilloscope is the most powerful instrument in our arsenal of electronic instruments. It is widely used for measurement of time-varying signals. Any time you have a signal that varies with time – slowly or quickly – you can use an oscilloscope to measure it – to look at it, and to find any unexpected features in it. The features you see in a signal when you use an oscilloscope to look at a signal are features you cannot see otherwise. In this lesson you will learn about oscilloscopes and you should keep this goal in mind as you proceed through the lesson. Given a time varying signal that you need information about, Be able to use an oscilloscope to portray the signal as a function of time. Be able to measure signal parameters with an oscilloscope.
