The FFT application module adds FFT (Fast Fourier Transform) measurement capabilities to your oscilloscope. The FFT process mathematically converts the standard time-domain signal (repetitive or single-shot acquisition) into its frequency components, providing spectrum analysis capabilities.
Being able to quickly look at a signal’s frequency components and spectrum shape is a powerful research and analysis tool. FFT is an excellent troubleshooting aid for:
FFT Windows
Four FFT windows (Rectangular, Hamming, Hanning, and Blackman-Harris) let you match the optimum window to the signal you are analyzing. The Rectangular window is best for nonperiodic events such as transients, pulses, and one-shot acquisitions. The Hamming, Hanning, and Blackman-Harris windows are better for periodic signals.
Analyze Repetitive, Single-Shot, and Stored Waveforms
You can display an FFT waveform on any actively-acquired signal (periodic or one-shot), the last acquired signal, or any signal stored in reference memory.
dB or Linear RMS Scales
The FFT vertical graticule can be set to either dB or Linear RMS. A dB scale is useful when the frequency component magnitudes cover a wide dynamic range, letting you show both lesser and greater- magnitude frequency components on the same display. A Linear scale is useful when the frequency component magnitudes are all close in value, allowing direct comparison of their magnitudes.
Time Signals and FFT Waveforms Displayed Together
The time signals and FFT waveforms can be shown together on the display. The time signal highlights the problem; the FFT waveform helps you determine the cause of the problem.
