Sound and Vibration Toolkit & NI-Scope: Zoom FFT
This VI continuously acquires data from the specified channel, scales the data to engineering units, windows the signal, and performs the requested averaged frequency measurement. Power Spectrum, Power Spectral Density, and FFT are available frequency measurements. The resulting spectrum is displayed on a waveform graph.

Based on the scan rate and the number of samples, the VI returns the frequency resolution and the period of the acquisition time.

This example demonstrates the compatibility between NI-SCOPE and SVT. It is a good illustration on how to modify other SVT examples to work with NI-SCOPE.

NOTE: Due to the hardware differences between DAQ/DSA devices and digitizers, not all SVT examples can be modified to work with NI-SCOPE.
