How does a DC power supply work?

February 14, 2025common problems 6530

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.

What is a digital multimeter?
February 14, 2025 771
A multimeter is an instrument that can measure a wide range of parameters, such as alternating (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and so on. Modern digital multimeters use digital and logic technology to become smaller and smaller with more and more built-in functions. By introducing digital technology, digital multimeters can provide graphical displays, data logging and signal digitization as well as...

What can a signal analyzer do?
February 14, 2025 859
Signal analyzers are capable of measuring the amplitude and phase of an input signal at a single frequency. The Signal Analyzer combines the large dynamic range of a swept-tuned spectrum analyzer with the power of a Vector Signal Analyzer (VSA) to perform in-channel measurements, such as Error Vector Magnitude (EVM) measurements, which require both magnitude and phase information. The VSAs are available in a wide range of sizes and sizes.

What is VNA?
February 14, 2025 832
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...

What is an impedance tester?
February 14, 2025 661
The article will cover the basics of impedance and points of measurement. Impedance is the resistance of an AC circuit and is invisible. Therefore, it must be measured using a specialized measuring instrument such as an impedance tester. People who have never touched an impedance tester before may be more concerned about how to use it and what to look for when using it. Therefore, this article will present in an easy-to-understand way the...
