How does a DC power supply work?

February 14, 2025common problems 3900

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...

How does a spectrum analyzer work?
February 14, 2025 575
A signal that looks very complex in the time domain behaves quite differently in the frequency domain. Time domain measurements show an impure sine wave. Without frequency domain measurements, it is still impossible to know the source and frequency of the second harmonic. Spectral analysis can show the spectral components individually, thus revealing the source of the interference. The information provided in the time domain (e.g., the signal pulse on...

What is the difference between an oscilloscope and a spectrum analyzer?
February 14, 2025 601
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. ,

What is a Real Time Spectrum Analyzer (RSA/RTSA)?
February 14, 2025 475
Real-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. ,
