What are the main types of spectrum analyzers?

频谱分析仪主要有两大类：扫频调谐分析仪和实时分析仪。现代频谱分析仪采用了数字信号处理技术，可以提供更多的测量功能，使您可以更轻松地解读测量结果。无论是扫频调谐分析仪还是实时频谱分析仪，它们均可显示幅度随频率的变化。不过，每种分析仪具体是如何处理和显示此信息的呢？实时频谱分析仪可以同时显示所有频率分量的能量。扫频调谐频谱分析仪则是按顺序显示测量结果，换句话说，它并非“实时”测量。这是因为扫频调谐分析仪使用了一个窄滤波器，此滤波器在一个频率范围内进行调谐以生成频谱显示。

How does a spectrum analyzer work?
February 14, 2025 478
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 resistor?
February 14, 2025 237
What is resistance in electricity? This article will cover the basics of resistance, how to calculate resistance, and resistors. Many people have heard the word "resistance" when they were students, but may still not understand it. However, because they don't understand it, they are hesitant to ask people about it now. Simply put, resistance is a force that flows in the opposite direction of the current. Resistance...

How does a DC power supply work?
February 14, 2025 283
A DC power supply converts alternating current (AC) electricity to DC electricity either by a linear method or 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 the frequency of electricity?
February 14, 2025 430
What does the frequency of electricity mean? Here are the basics of frequency, regionality, and measurement Since electricity and voltage are invisible things, many people will think they are elusive. But in fact, they are only invisible, and it is not difficult to understand them. Below, we will introduce the frequency basis of electricity and voltage in an easy-to-understand way, regional differences in frequency, and how...
