NI LabVIEW: FFT subVI to compute magnitude spectrum

Practical details necessary to using the LabVIEW built-in FFT subVI to compute the magnitude spectrum of a time-domain signal, including: array size N, polar form conversion of the complex-valued output, scaling by N to obtain normalized spectrum, and retaining only the lower half of the output array for display.
