Math FFT
This chapter contains detailed informat ion on how to use the Math
FFT (Fast Fourier Transform). You can use the FFT Math mode to
convert a time-domain (YT) signal into its frequency components
(spectrum). You can use the Math FFT mode to view the following
types of signals:
H Analyze harmonics in power lines
H Measure harmonic conte nt and distortion in systems
H Characterize noise in DC power supplies
H Test impulse re sponse of filters and systems
H Analyze vibration
To use the Mat h FFT mode, you need to perform the following tasks:
H Set up the source (time-domain) waveform
H Display the FFT spectrum
H Select a type of FFT window
H Adjust the sample rate to di splay the fundamental frequency and
harmonics without aliasing
H Use z oom controls to magnify the spectrum
H Use c ursors to measure the spectrum
