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.
Many people use digital multimeters to easily measure current, voltage, resistance, etc. However, there is a drawback to using a digital multimeter to measure current, namely: the circuit must be disconnected and the digital multimeter must be connected in series with the circuit under test in order to make the measurement. In this case, a current probe can be used instead of a digital multimeter to make measurements. Since the electrical connection of the circuit is no longer required, the current probe is more time-consuming...
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...

To connect two DC power supplies in series, connect the positive terminal of the first power supply to the negative terminal of the second power supply to form a "daisy-chain" connection, where the series voltage is the sum of the voltages of the two power supplies. To connect two DC power supplies in series, proceed as follows: Note that the voltage of the load should be equal to or higher than the sum of the voltages of the two power supplies to prevent damage to the load or power supply. In addition, the load's rated...
