One of the most used testing equipment in various industries is satellite spectrum analyzer. A spectrum analyzer is simple equipment that is used to measure the strength of the signal. The signal is compared with the full signal range of the device. A spectrum analyzer is an invaluable testing device that is used for testing, maintaining and designing the radio frequency circuitry. According to the experts, the basic use of the spectrum analyzer is to measure the power of the known as well as unknown signals.
To people who are not well versed with the satellite spectrum analyzers, it might look like an oscilloscope. However, there is a huge amount of difference between the satellite spectrum analyzers and oscilloscope. An oscilloscope calculates the signals in the time domain while a satellite spectrum analyzers measure the signals in the frequency domain.
Types of spectrum analyzer:
Real-time
The real-time analyzers assemble the real-time bandwidth of the signals in a fixed time. The signals are always incoming. These analyzers convert the information using the FFT algorithm. The information from the signals is calculated in the real-time which means that there are no gaps in the information assembled.
FFT/ Fast Fourier transform
A Fast Fourier transform spectrum analyzer or an FFT analyzer. This analyzer has a unique way to assemble information from the signals. This particular analyzer needs the signal with a minimum of twice bandwidth.
Swept or superheterodyne
A superheterodyne or swept spectrum analyzer works when the signals have a small bandwidth. Small bandwidths give maximum spectral resolution and make sure that the information is properly filtered and analyzed accordingly.
Audio
The audio analyzers are wavelengths analyzers that are used by the sound engineers to make various frequencies audible to the human ears.
The satellite spectrum analyzers offer the tester opportunity to center, stop and start the frequency as they wish. The numerous kinds of analyzers in the market measure the signals in their own way.
