Load From Data File
Several static frequency data traces may be displayed in the plot by loading them from data
files that were previously exported from the FFT Analyzer tool.
Add New Average Curve
Static FFT data traces may also be created by loading data from 1 or more FFT data files
and averaging the data to create a new spectrum. The loaded files must
contain data with the same measurement units. When source data with differing frequency
resolutions is loaded, the resolution of the new average curve will be defined by the
largest (coarsest) resolution of all spectra included in the average.
