Test engineers and developers use oscilloscopes to display, visualize graphs, and analyze electrical signals during research and development, verification, quality assurance, and troubleshooting or debugging of electronic systems, boards, and integrated circuits. Oscilloscopes play a key role in a variety of applications and technologies across all industries, including high-speed digital electronics, optical communications, radio frequency, power electronics, automotive and aerospace and defense.
Oscilloscopes are key test instruments for observing, analyzing, or recording the behavior of electrical signals. Some specific use cases for oscilloscopes in electronics labs include measuring voltage waveforms, analyzing electronic signals, detecting unwanted noise and crosstalk, and evaluating harmful transients in power systems.
In high-speed signal analysis, oscilloscopes can measure signal integrity by displaying and measuring eye diagrams, including eye height and eye width. Mixed-signal oscilloscopes can help debug digital circuits by displaying the logic state and timing of measured digital signals. Advanced oscilloscopes can even help simulate ideal reference receivers for transmitter testing, measure fiber optic signals using optoelectronic converters, and analyze RF signals.
Because of their versatility, oscilloscopes have many different performance levels and software features depending on the application. They are indispensable tools in electronics development, troubleshooting and analysis.
Alternating current is suitable for transmission and distribution of electricity over long distances through the grid system. Direct current is a one-way flow of charge and is more reliable than alternating current, but is not suitable for long-distance transmission. Most electronic devices use DC because their voltage is constant, such as devices powered by batteries. Some devices also use rectifiers to convert AC to DC. Power supplies usually have an internal...

A DC power supply provides a constant bias voltage or current to an electrical device, component, or circuit to ensure that the device under test operates as intended. ,
An oscilloscope is a test instrument used to capture and display a graph of the waveform of an electrical signal over time. For example, it can graph voltage (y-axis) versus time (x-axis) on its display. Oscilloscopes are powerful tools for designing and testing electronic equipment. They play a very important role in determining whether system equipment components are working properly and which components are malfunctioning. They...
