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

February 14, 2025common problems 8800

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 does a spectrum analyzer work?
February 14, 2025 873
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 a function/waveform generator?
February 14, 2025 771
A function generator is an electronic test device that generates a variety of standard waveforms for a device under test (DUT), such as sine, square, ramp, or sawtooth waveforms. In circuit design and circuit boards, testing often requires the use of controlled signals to simulate routine operations. Testing physical systems and sensors often requires stable and reliable signals that are as low as a few microvolts and may be as high as...

What are the advantages of Trueform technology?
February 14, 2025 751
Its advantages include: Ultra-low jitterTrueform function/arbitrary waveform generators have jitter as low as 1 ps and excellent edge stability. You can even use them as system clocks for timing and triggering other instruments. Thanks to better jitter performance, you can locate edges more accurately, which helps reduce timing errors in circuit design. Ultra-low...

How do I measure the current?
February 14, 2025 794
Why 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...
