Oscilloscopes have long been the go to tool engineers relied for debugging problems in the designs and analyzing signals in the systems. The first oscilloscopes were analog and did a great job of accurately displaying the signal being probed directly on the display. These oscilloscopes, although providing tremendous insight into electrical systems, came with some limitations. For example, it was not easy to make measurements on that signal or save any results and findings. As digital oscilloscopes were developed the user had access to a new set of tools for debugging problems. New digital oscilloscopes sampled incoming waveforms and recreated them on the display, the digital waveforms could be analyzed with a wide variety of mathematical and measurement tools. Waveform data could be saved and manipulated providing tremendous insight into the system being tested.
