Spectrum analyzers are electronic test instruments used to measure the frequency spectrum of an electrical signal. They are used in a variety of applications, including telecommunications, audio engineering, and RF engineering. Spectrum analyzers measure the magnitude of an input signal versus frequency within the full frequency range of the instrument.
Spectrum analyzers are used to measure the frequency of a signal, its power, and its spectral purity. They are also used to detect and measure interference, to determine the modulation characteristics of a signal, and to measure the noise level of a system. Spectrum analyzers are used in a variety of industries, including telecommunications, aerospace, automotive, and medical.
The price range for a spectrum analyzer depends on the type of instrument, the features, and the manufacturer. Prices range from a few hundred dollars for a basic model to several thousand dollars for a high-end model. Popular manufacturers of spectrum analyzers include Anritsu, Rohde & Schwarz, Tektronix, and Keysight Technologies.
