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.
Vector network analyzers measure a wide variety of devices and networks and offer a wide range of measurements for a variety of usage scenarios, such as spectrum analysis, pulse measurements, power amplifier (PA) characterization, and active device testing. The following guide describes how to set up a network analyzer for measurements, calibrate the measurement system, and interpret the measurement results: The uses of VANs are so wide-ranging that each measurement...
What is resistance in electricity? This article will cover the basics of resistance, how to calculate resistance, and resistors. Many people have heard the word "resistance" when they were students, but may still not understand it. However, because they don't understand it, they are hesitant to ask people about it now. Simply put, resistance is a force that flows in the opposite direction of the current. Resistance...
Alternating current (AC) is a type of electric current whose polarity reverses periodically and whose amplitude varies continuously over time. AC power is often used in businesses and homes because it is cheaper and more efficient to generate and transmit than direct current (DC) power. During transmission, a transformer can reduce power loss by increasing or decreasing the voltage of the AC line. Alternating current (AC) is a form of household electricity -...
Want to know how to use the current probe? Please first understand the following basic usage of the current probe and precautions for use. Since electricity is invisible, it is not possible to immediately determine whether a malfunction has occurred. In some cases, current measurements are required on a daily basis to prevent malfunctions, as well as to identify the cause of malfunctions when they do occur. Digital multimeters, clamp meters, and current probes can be used...
