FFT Averaging dialog box

Performs FFT (Fast Fourier Transform) averaging of a time function.

Qualifying Records table
Qualifying Records	Displays the available AFU records.
Show All	Displays all records in the loaded AFU.If you clear this check box, the table displays only the functions available that can be processed by the conversion.
AFU Name column	Lists the AFU loaded to the model.
Record Name column	Lists the record identifier.
Function Type column	Lists the function type (Frequency, Time, and so on).
Abs Unit column	Lists the abscissa (x-axis) units.
Ord Unit column	Lists the ordinate (Y-axis) units.
Add AFU Records	Adds a function to the table.Select the function from a loaded AFU file in the XY Function Navigator and click .
Remove AFU Records	Removes a function from the table.Select the function in the table and click .
Input Parameters
Averaging Type	Select the type of averaging to perform.LinearAdds the spectrums and then divides the total by the total number of spectrums. There is no additional weighting applied to any spectrum.ExponentialGenerates a continuous running average where the most recently collected spectrum has more weight on the average than older ones. Weights the most recent data using an exponential method according to the exponential setting (Light = 2, Medium = 5, Heavy = 8).Peak HoldSaves the maximum magnitude of each spectrum at each frequency without taking the average.
Weighted Value	Available when you select Exponential. Displays the Weighted Value.Sets the exponential method Weighted Value for successive frames in the averaging process (Light = 2, Medium = 5, Heavy = 8).
First Start Point	Sets the starting time point to be used for the data frames.
Frame Size	Sets the number of data intervals for each spectrum frame.128Uses 128 intervals.256Uses 256 intervals.512Uses 512 intervals.1024Uses 1024 intervals.2048Uses 2048 intervals.4096Uses 4096 intervals.
Overlap Percent	Sets the overlap percent of each data frame in the frequency domain.
Frames per Average	Sets the number of frames used in each average computation.
Output
Output Setting	Specifies how the software should write the resulting data in the AFU file.AppendAppends the new function to an existing function.OverwriteOverwrites an existing function with the new function.Other AFUSelects a new AFU to save the function.
AFU File	Appears when Output is set to Other AFU.Sets the path and file name of the AFU file where the resulting data will be saved.You can also click Browse to select the file location.
