The purpose of a spectrum analyzer is to measure the power of the spectrum of known and unknown signals. Spectrum analyzers can measure the amplitude of an input signal compared to the frequency range of the device.
There are two different methods that can be used during signal measurement in the frequency domain. The first method is called Fast Fourier Transform (FFT), digital technology, and uses mathematic formulas to obtain the frequency spectrum of a signal. The process involves a sample of the signal in the time domain that is then transformed into a digital format. Fourier analysis then transforms this measurement to display the signal in the frequency domain. The second method is called Swept-Tuned Analysis, analog technology, and involves a sweep generator being placed on the device to control the local oscillator (LO). The input signal is mixed with this to assure only the specified frequency range determined by the sweep generator is viewed. lastly, an amplifier and filter are used on the mixed signal to obtain the spectrum.
