FFT Analysis  Narrow Band Spectral Analysis

The FFT module offers standard to advanced analysis results:

• Trigger blocks, averaged in time domain or instantaneous, weighted or not
• Spectra (up to 25601 lines at 40 kHz) , instantaneous, averaged in spectral or time domain, averaged complex
• Cross-spectra, FRFs (H1, H2), coherence, cross-spectra
• Lissajous, envelope demodulation
• Orders, overall bandwidth tracking
• Acoustics and human vibration weightings
• Any units: RMS, Peak, pk-pk, PSD, ESD, RMS PSD
• Any integration: single/double integration (from acceleration to displacement), single/double differentiation (from velocity to angular acceleration)
