An instrument that measures the magnitude of an input signal against the full range of frequency range of the instrument is called spectrum analyzer. The main function of a spectrum analyzer is to measure the power of known and unknown signals of the spectrum. A spectrum analyzer generally measures electrical input. However, an appropriate transducer converts other signals, such as optical light waves and acoustic pressure waves.
A spectrum analyzer is an electronic device that is used to display variations in the signal strength. Spectrum analyzers have a close resemblance to oscilloscopes. Spectrum analyzers are used for research and study purposes in universities and laboratories and for designing, manufacturing, or repairing electronic equipment.
The overall test and measurement equipment market is expected to grow from USD 25.7 billion in 2018 to USD 32.3 billion by 2024, at a CAGR of 3.90% during the forecast period. The market is growing due to the increasing demand for this equipment in end-use sectors, such as automotive & transportation, aerospace & defense, IT & telecommunications, education & government, semiconductor & electronics, industrial, and healthcare.
