Perform FFT on a Report

You can perform FFT on an existing 2D plot by using the Results > Perform FFT command. This opens the Perform FFT on Traces in Reports dialog box.

Select the report you want from the list in the dialog box.
Select the FFT Window type from a drop-down menu.

Windowing functions cause the FFT of the signal to have non-zero values away from w. Each window function trades off the ability to resolve comparable signals and frequencies versus the ability to resolve signals of different strengths and frequencies.

Select the function to apply to complex data.

The new report displays and appears in the Project Manager tree. The new report name prefixes FFT to the name of the original report. Trace names are also prefixed with FFT.
