What are the main types of spectrum analyzers?

February 14, 2025common problems 4380

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。

What is a digital multimeter?
February 14, 2025 400
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 are the different types of oscilloscopes?
February 14, 2025 556
All modern oscilloscopes are digital storage oscilloscopes (DSOs) that use digital signal processing to capture and display analog signals. If the oscilloscope has the ability to observe these signals simultaneously in the digital domain, it is a mixed-signal oscilloscope (MSO). If the oscilloscope has a built-in spectrum analyzer function, it is a mixed-domain oscilloscope (MDO), although this term is less common. ,,...

How to use the current probe
February 14, 2025 472
Want to know how to use the current probe? Please first understand the following basic usage of the current probe and precautions for use. Since electricity is invisible, it is not possible to immediately determine whether a malfunction has occurred. In some cases, current measurements are required on a daily basis to prevent malfunctions, as well as to identify the cause of malfunctions when they do occur. Digital multimeters, clamp meters, and current probes can be used...
