Sound and Vibration Toolkit & NI-Scope: Baseband FRF
This VI continuously acquires data from two channels in the same device. No source is provided. Triggering from either channel is supported.
The data from each channel is scaled to engineering units, windowed, and the frequency response is computed. The results of the frequency response measurement can be displayed on a Bode plot or a Nyquist plot. The coherence is also graphed to evaluate the validity of the measured frequency response.
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.
