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 failing. They can also help you determine if newly designed components are working as expected. This can be done by analyzing signal parameters such as amplitude, period, frequency, rise time, and pulse width. Modern digital oscilloscopes can also perform mathematical operations on waveforms, such as Fourier transforms, for faster analysis.
Vector network analyzers (VNAs) are test instruments that measure electrical network parameters. They are essential for radio frequency (RF) and microwave component analysis of a wide variety of passive and active devices including filters, antennas and power amplifiers. Network analyzers are ideal for transmission, reflection and impedance measurements as well as s-parameter measurements during design and production. Network analyzers...
View Full VersionWhy do you need to measure current? In this article, we will cover the reasons for measuring current, how to measure current and what to look for when measuring current. We cannot see the current that is flowing with our own eyes. Therefore, specialized measuring instruments are needed to measure current and other parameters. But why do we need to measure current? And how should we measure it? This article will detail the reasons for the need to measure current...

View Full VersionThis article describes its basic information and how it differs from an analog multimeter. ■ Summary The condition of an electronic device needs to be determined using a measuring instrument. For electronic devices whose condition cannot be determined visually, it is recommended that measurements be made with a digital multimeter. In this section, basic information about digital multimeters such as "What is a digital multimeter" and "Is there a difference between a digital multimeter and an analog multimeter" will be explained in detail...
