What are the different types of spectrum analyzers?
Today, there are three basic types of analyzer: the swept-tuned spectrum analyzer, the vector signal analyzer, and the real-time spectrum analyzer.
What is the principle of spectrum analyzer?
A spectrum / signal analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals.
Is spectrum analyzer the same as FFT?
Fourier (or FFT) analyzers
The Fourier or FFT spectrum analyzer is another real-time spectrum analyzer implementation. The Fourier analyzer, also referred to as a dynamic signal analyzer, use digital signal processing to sample the input signal and convert it to the frequency domain.
What is FFT spectrum analyzer?
The FFT spectrum analyzer samples the input signal, computes the magnitude of its sine and cosine components, and displays the spectrum of these measured frequency components. Why Look at a Signal's Spectrum? For one thing, some measurements which are very hard in the time domain are very easy in the frequency domain.
