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 power 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 built-in rectifiers and transformers that can raise or lower the voltage to a suitable level.
An oscilloscope captures and displays signals in the time domain, while a spectrum analyzer captures and displays signals in the frequency domain. Sometimes, oscilloscopes have a built-in spectrum analyzer function to make it easy to analyze signals in both the time and frequency domains. ,
View Full VersionReal-time spectrum analyzers can collect data in the time domain and then convert it to the frequency domain using the Fast Fourier Transform (FFT). Real-time spectrum analyzers can quickly capture transient and fast signals. ,
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 VersionWant 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...
