What is a Spectrum Analyzer?
A spectrum analyzer is an instrument that studies the spectrum structure of electrical signals. It is used to measure signal parameters such as signal distortion, modulation, spectral purity, frequency stability, and intermodulation distortion. It can be used to measure certain circuit systems such as amplifiers and filters. Parameter is a versatile electronic measuring instrument. It can also be called a frequency domain oscilloscope, tracking oscilloscope, analysis oscilloscope, harmonic analyzer, frequency characteristic analyzer, or Fourier analyzer. Modern spectrum analyzers can display the analysis results in analog or digital mode, and can analyze electrical signals in all radio frequency bands from very low frequencies to sub-millimeter bands below 1 Hz. If digital circuits and microprocessors are used inside the instrument, which have storage and operation functions, and equipped with standard interfaces, it is easy to form an automatic test system.
Spectrum Analyzer
- Spectrum analyzers are divided into two types: real-time analysis and frequency sweeping. The former can obtain all the required spectrum information and analyze and display the analysis results within the actual time of the measured signal occurrence; the latter needs to complete the repeated information analysis through multiple sampling processes. The real-time spectrum analyzer is mainly used for non-repetitive, short-term signal analysis. The non-real-time spectrum analyzer is mainly used for the analysis of continuous RF signals and periodic signals from the audio frequency to the sub-millimeter band.
- Swept spectrum analyzer
- Sweep frequency with display device
- The main technical indicators of the spectrum analyzer are frequency range, resolution, analysis spectrum width, analysis time, and frequency sweep.
- How a Spectrum Analyzer Works
- The spectrum analyzer architecture is like an oscilloscope for time domain use. Many function control buttons are arranged on the panel to adjust and control system functions. Real-Time Spectrum Analyzer and Sweep-Tuned Spectrum Analyzer). The function of the real-time frequency analyzer is to display the signal amplitude in the frequency domain at the same instant. Its working principle is to have corresponding filters and detectors for different frequency signals, and then through a synchronized multi-task scanner The advantage of transmitting the signal to the CRT screen is that it can display the transient response of periodic random waves (Periodic Random Waves).
- Hard keys, soft keys, and knobs
- This is the basic means of operation of the instrument.
- 1. Three large hard keys and one large knob: The function of the large knob is set by three large hard keys. Press the frequency hard key once, the knob can fine-tune the display of the instrument
