Signal analyzers play an important role in the field of electronic measurement. According to their functions and characteristics, they can be mainly divided into two categories:
1. General signal analyzer: This type of signal analyzer has relatively comprehensive functions and can perform extensive analysis on different types of signals. It can not only perform time domain analysis to observe the waveform, period, amplitude and other parameters of the signal, but also perform frequency domain analysis to reveal the frequency distribution and power spectrum density of the signal through methods such as Fourier transform. In addition, some advanced general signal analyzers also have the ability of modulation domain analysis, which can analyze the modulation characteristics of the signal, such as amplitude modulation (AM), frequency modulation (FM), etc. This type of analyzer is usually suitable for scenarios where a comprehensive understanding and evaluation of signal characteristics is required, such as communication systems, audio processing, vibration analysis and other fields.
2. Spectrum analyzer: As a special type of signal analyzer, the spectrum analyzer focuses on the spectrum analysis of the signal. It helps users intuitively understand the spectrum characteristics of the signal by decomposing the signal into components of different frequencies and displaying the distribution and power of these components in a graphical way. Spectrum analyzers are widely used in wireless communications, radar detection, satellite communications and other fields. They are mainly used for signal analysis and optimization, frequency band planning and interference location.
In summary, signal analyzers are mainly divided into two categories: general signal analyzers and spectrum analyzers. They play their own unique roles in the field of electronic measurement.
