How does a DC power supply work?

February 14, 2025common problems 5660

A DC power supply converts alternating current (AC) electricity to DC electricity either by a linear method or by a switching method. Switching power supplies are more efficient, lighter in weight and smaller in form factor. Linear power supplies can achieve lower noise, but this is no longer an advantage with modern switching power supplies.

If you want to measure current, voltage, etc., you need specialized measuring equipment. Analog and digital multimeters are usually used to measure current, but the circuit must be cut off and the multimeter and the circuit connected in series in order to make the measurement. However, it is not uncommon that it is not possible to disconnect the circuit in some cases. In addition, there is a danger of electric shock when the circuit is disconnected. In this case the clamp meter...

The selection criteria for a VNA depends heavily on the application or usage scenario. Typically, selection criteria include frequency range, number of ports required (from 2 to 24 (multiport) and even 48 (with switching matrix)), output power, and instrument class from economy to handheld to high-end. Vector network analyzers are both signal generators and receivers...

How does an oscilloscope work?
February 14, 2025 595
An oscilloscope uses a probe to connect to a test point in a circuit and amplify or attenuate the voltage at that point. The subsequent signal path depends on the oscilloscope, but in general, analog circuits condition the signal and analog-to-digital converters digitize it for further evaluation, processing, and analysis. ,

Digital multimeters are used, and this article will detail their advantages and disadvantages. ■ SUMMARY Electronic devices are powered by electricity. However, because electricity is invisible, it is necessary to use measuring instruments such as digital multimeters to check their safety and quality and to find out why malfunctions occur. Digital multimeters have so many buttons and ports that many people find them difficult to manipulate at first...
