Product Description

FFT Analyzer

The FFT or Fast Fourier Transform spectrum analyser is now being used increasingly to improve performance reduce costs in RF design, electronics manufacturing test, service, repair. With increasing use of wireless technology used in the electronic circuit design of electronic devices, improved performance from spectrum analyzers is growing in importance.

As the name suggests the FFT spectrum analyzer is an item of RF test equipment that uses Fourier analysis and digital signal processing techniques to provide spectrum analysis.

Using Fourier analysis any waveform in the time domain can be represented by the weighted sum of sine and cosine signals. Using this concept, the FFT spectrum analyzer samples the input signal. It then computes the magnitude of its sine and cosine components of the overall signal, and finally it displays the spectrum of the signal.
