FlexPro Spectral Analysis Option
Introduction
With FlexPro's Spectral Analysis Option, you enter a new world of software engineering.
You'll save precious time by eliminating the programming or multi-step UI procedures that are normally required for performing sophisticated spectral analysis. By using real-time 2D and 3D spectral graphs, the new FlexPro's Analysis Wizard offers immediate visual feedback when changing algorithms, algorithm parameters, and spectral formats.
Quickly locate your signal components
FlexPro's Spectral Analysis Option gives engineers and researchers the power to rapidly find the components of complex signals. A rich set of spectral analysis procedures helps you make intelligent signal content conclusions for any application. The built-in spectral analysis procedures include: FFT, AR, ARMA, Eigenanalysis, Continuous Wavelets, Cross-Spectra, Coherence, and Transfer Function Estimation.
Identify frequency and power with Fourier analysis
Get a complete picture of the frequency signature of a signal using up to five different Fourier spectrum methods. Solve the leakage problem found with a standard FFT by using one of the thirty built-in data-tapering windows. The latest innovations in algorithms, adaptive spectra, and peak determination help you to better characterise the frequency and power of each signal component. You can even manage unevenly spaced data with Fourier techniques originally developed by astrophysicists.
Effortlessly analyse non-stationary data
Simultaneously find the time and frequency localisation components of a non-stationary periodic signal with Short-Time Fourier Transform or Continuous Wavelet Transform methods. For the CWT, the Spectral Analysis Option gives you a choice of three adjustable wavelets in order to find the optimum time-frequency resolution tradeoff.
Principal component modeling
The Spectral Analysis Option offers state of the art methods for isolating the spectra of the principal components within a signal. These methods remove of the influence of noise in the AR SVD, ARMA SVD, and Eigen-decomposition procedures, enabling you to optimise the estimation of narrowband components.
Harmonic analysis
Advanced parametric sinusoidal modeling is offered with your choice of frequency estimation methods. The number of harmonics or spectral peaks can be set directly by count or indirectly by spectral threshold.
