What is the difference between an oscilloscope and a spectrum analyzer?

February 14, 2025common problems 6040

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.

How do I connect two DC power supplies in series?
February 14, 2025 467
To connect two DC power supplies in series, connect the positive terminal of the first power supply to the negative terminal of the second power supply to form a "daisy-chain" connection, where the series voltage is the sum of the voltages of the two power supplies. To connect two DC power supplies in series, proceed as follows: Note that the voltage of the load should be equal to or higher than the sum of the voltages of the two power supplies to prevent damage to the load or power supply. In addition, the load's rated...

What is voltage? An easy-to-understand explanation of the difference from current and knowledge of units of measurement ■ Outline When using electronic equipment, you need to have a clear grasp of current, resistance, and voltage. However, there are many people who only know these words and do not understand them in detail. Here, we will explain in layman's terms what the definition of voltage is, what the difference between current and potential is,...

What are spectrum analyzers used for?
February 14, 2025 624
Spectrum analyzers measure the amplitude of an input signal versus frequency over the entire frequency range to determine the power of the signal. Spectrum analyzers are capable of performing tests such as noise figure and signal-to-noise ratio (SNR) to characterize the performance of a device and its contribution to overall system performance. For more information, see the application guide Spectrum Analysis Basics. ,
