The oscilloscope is a very helpful device that has been in use in a wide range of industries, as well as laboratories, for more than a hundred years now. The scopes are able to measure time varying electrical signals, and they can help to calibrate and find the faults of many pieces of equipment. A number of different types of these scopes are out there today, and each has particular pros and cons. Some applications may be easier with one type of scope, while others may work better in different situations.
