Frequency Domain Cluster (Power Spectrum, FFT) to 2D Array in LabVIEW

[EricS.]

Overview

This VI will take any cluster of frequency domain data, such as a Power Spectrum or FFT, and converts it into a 2 dimensional array which can be saved to Excel or a text file.

Description 

The frequency domain cluster contains three components: f0 (initial frequency), df (frequency step along X-axis), and magnitude (1D array of magnitude values).

This VI uses f0 and df to create a 1D array of frequency values, and then combines that with the 1D magnitude array.

The result is a 2D array, where the first dimension is frequency data and the second dimension will contain the magnitude at the respective frequency.

Requirements: LabVIEW Base Development System 2012 or compatible

Steps to Implement or Execute Code

1. Enter the Frequency Domain Cluster array or Use this VI as subVI
2. Run the VI
