Introduction
The oscilloscope will be used to visualize time-varying signals, generally voltages. This document specifically relates to the Keysight DSOX1202A Oscilloscope.
Background
An oscilloscope is used to view a voltage waveform on a screen. Modern oscilloscopes are called digital storage oscilloscopes. They use very fast analog-to-digital conversion to record and show voltage waveform data digitally on a built-in monitor screen, typically a liquid crystal display (LCD) flat panel. Digital storage oscilloscopes have display storage, high-accuracy, and flexible triggering. The capture of momentary traces for analysis later is a standard capability of these instruments. This capability makes it possible to view rare or intermittent events and provide a troubleshooting capability that other electronic test equipment cannot.
Additional features of the digital oscilloscope include math functions (e.g. rise time, pulse width, amplitude, addition of two waveforms, subtraction, and averaging), histograms, statistics, persistence maps, signal analysis (e.g. Fourier transforms in the frequency domain), and external data storage (including LAN, WAN, USB, and floppy devices). Digital oscilloscopes are limited principally by their analog input circuitry and sampling frequency, which determines how often the value of the signal is captured (or sampled). For proper waveform display, the highest frequency in a signal must not exceed the {\it Nyquist frequency}, which is half the sampling rate of the data acquisition system. Otherwise, distortion referred to as aliasing occurs, which means the higher-frequency components of the signal take on the identity (i.e., alias) of lower-frequency components.
