 Zoom image | - Two extensions add FFT analysis capabilities to the free base package.
- QuickDAQ FFT Analysis Options allow serious sound & vibration analysis supporting modal analysis and ODS analysis methods.
- Single-Channel and Dual-Channel (frequency response) FFT operations
- Switch between the Data Logger time-based interface and the FFT Analyzer block/average-based interface
- QuickDAQ Base Package (Free)
◦ Ready-to-measure application software
◦ Configure, acquire, log, display, and analyze your data
◦ Customize many aspects of the acquisition, display, and recording functions,
including the acquisition duration, sampling frequency, trigger settings, and
sensor configurations to use
◦ On each device acquire data from analog input, counter, tachometer, quadrature
decoder, and digital input channels
◦ Use QuickDAQ in one of two modes:
- Acquisition mode allows you to acquire data
- File Reader mode allows you to view a previously recorded data file
◦ Generate output stimuli (hardware dependant): fixed waveforms, swept sine
waves, or noise signals.
- FFT Analysis Option (License Required)
◦ Includes all the features of the QuickDAQ Base Package
◦ Perform single-channel FFT operations including:
Auto Spectrum, Spectrum, Power Spectral Density
◦ Configure and view dynamic performance statistics: IBF, THD, SFDR, SINAD,
SNR, ENOB
◦ Supports Hanning, Hamming, Bartlett, Blackman, Blackman Harris, and Flat Top
response window types
◦ Configure Digital IIR Filters (Bessel, Butterworth, Chebyshev) as low-pass,
high-pass, band-pass, or band-stop
- Advanced FFT Analysis Option (License Required)
◦ Includes all the features of the QuickDAQ Base Package and
FFT Analysis Package
◦ Perform 2-channel FFT operations including:
Frequency Response Functions (Inertance, Mobility, Compliance, Apparent Mass,
Impedance, Dynamic Stiffness, or custom FRF) with H1, H2, or H3 estimator
types, Cross-Spectrum, Cross Power Spectral Density, Coherence,
Coherent Output Power
◦ Supports real, imaginary, and Nyquist display functions
◦ Additional FFT analysis functions supported: Exponential, Force, Cosine Taper
◦ Save data to UFF file format
