Converts an evenly spaced spectrum of the form {x0 dx [Y]} to XY data of the form {[X] [Y]}.

spectrum cluster specifies the evenly x-spaced data input to the VI as well as the starting x value and the increment between successive points. This type of output is common for FFT-based spectra.
x0 specifies the minimum value of the x-axis.
dx specifies the x-axis interval between points in the input data.
Y specifies the increment between successive points.
XY cluster returns the same spectrum data in XY format, which is a cluster of an X array and a Y array. The implicit abscissa channel specified by x0, dx, and the number of elements in the data array is now expressed explicitly in the X array of the XY cluster.
X returns the explicit array built from the specified start, increment, and length.
Y returns the number of elements in the data array.
