Typically, Fourier transformation of time-domain waveforms requires the execution of the computationally-intensive Fast Fourier Transform (FFT) algorithm on a host PC. Gage’s eXpert FFT firmware now removes this computational load from the host PC and performs the FFT calculations on waveforms acquired by CompuScope hardware during PCI transfer.

Features
  • Performs 512, 1024 or 2048 point FFTs on time-domain waveforms acquired by CompuScope hardware
  • Removes FFT calculation load from host PC
  • Downloads multiple FFT spectra in a single PCI transfer
  • Real and Imaginary FFT amplitude components are separately available
  • Standard and customized time-domain Windowing included
  • Dedicated FFT Sample Program included in CompuScope Software Development Kits (SDKs) for C/C#, LabVIEW and MATLAB.
