That's the measure of how sensitive the display dot is to voltage applied to the input terminals. Sweep speed is usually measured in units of time per distance, like milliseconds/centimeter or milliseconds per division.This might also be referred to as the horizontal sensitivity. These are functions you can control on most oscilloscopes: Sweep speed. Before we start building and programming, lets review some basic characteristics of an oscilloscope. We will be using the Arduino analog A0 input to sample and capture time varying signals by Writing a program that will also display those signals in a 3.8" TFT LCD touch display, and we will input data to modify the oscilloscope behavior, using the touch capabilities of the screen display. You will learn about the Arduino mega analog to digital converter( ADC). We can use an oscilloscope to observe and study signal characteristics that we could otherwise not see. Any time you have a signal that varies with time( slowly, quickly, and /or periodically ) you can use an oscilloscope to measure it, visualize it, and to find any unexpected features in it. It is mainly used to measue time-varying signals. This instructable will show you how to build a portable Touch Screen Oscilloscope for less than 40 U$! The oscilloscope is one of the most powerful electronic instruments that is available to electronics hobbyist, experimenters, and engineers.
