Sound and Vibration Toolkit & NI-Scope: One Shot THD
This VI acquires data for a single-shot acquisition and performs a total harmonic distortion (THD) measurement on the acquired response channel. You can specify the sampling rate to use for the input channel and the integration time to use for the measurement.

The graphical outputs display the time record, the magnitude of the FFT, and the relative contributions of the selected harmonics to the THD, respectively.

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
