Perform efficient data analysis on live data or an imported file with the fast Fourier transform (FFT). View changes in frequency and amplitude in a waveform, highlight harmonic excitation in a broad frequency range, and more.
Download Demo All Software FeaturesObserVIEW responds to any change to the settings with a fast and automatic recalculation of the computed parameters. The software can perform the calculation on live data streaming from Live Analyzer or an imported file.
Features of ObserVIEW’s FFT analysis include:
When VR hardware is connected to a Live Analyzer session, the user can access all analysis controls while live data are streamed in from the device. The user can pause the incoming data to perform a more in-depth analysis and/or export the waveform. They can then resume the live feed without losing any of the data that occurred while the stream was paused so long as the data was paused for less than the user-configurable buffer duration period.
The copy and paste command in ObserVIEW allows the user to move data between graphs and software applications. In doing so, the user can perform an easy comparison of data from a multitude of applications. This can be useful for comparing graph data from different time locations, multiple test results, various test environments, and much more.
In engineering, the frequency domain is the usual domain for analysis. The fast Fourier transform (FFT) is a computational algorithm that efficiently implements a mathematical operation called the discrete-time Fourier transform. It transforms time-domain data into the frequency domain by taking apart a signal into sine and cosine waves.
In a complex signal, the FFT helps the engineer to determine the frequencies that are being excited and the amplitude at each frequency. Additionally, it highlights the changes in frequency and amplitude and the harmonic excitation in a frequency range.
For a complex signal, the FFT can help to answer:
The user can easily view changes in frequency and amplitude in a waveform and highlight harmonic excitation in a broad frequency range.
ObserVIEW includes the industry-standard window functions including Blackman, Hamming, and Hanning. The Help file also includes a comprehensive table of window functions for assistance with selection.
