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.
A network analyzer consists of a signal source and a receiver. The receiver will detect changes in the output signal of the device (or network) and then compare it to the source signal fed into the device. To evaluate the effect of the device on current and voltage, the VNA measures the resulting amplitude and phase response. This results in transmission and reflection measurements, impedance and s-parameters, which can be used by the test engineer to...
This article will detail the basics of a clamp meter and the principles of measurement. When it comes to instruments that measure current, many people may think of analog or digital multimeters. However, if you want to make measurements without breaking the circuit, a clamp meter is recommended. Direct wiring method ...
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...
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...
