  2. Under Input Result Files, click for Result File 1 and browse and select a .PCH file.
    Note: You can load more .PCH files from different loading conditions for Result File 2 and Result File 3. The same applies to the Scale Factor inputs, which can be used to convert the results from meters to millimeters or vice versa.
  3. Under Input Channels, map the CBUSH IDs from the different files to the respective openings and rename each channel to represent them properly.
  4. Under Frequency Filter, enter low and high cutoff frequencies.
  5. Under Plot Type, select the desired direction and SEP (Statistical Evaluation Parameter) value.
  6. Select one of the plots (Cutoff Freq, Band pass Freq, or Dynamic DD) and click Display.
    A new page is created for the selected plot with the number of selected channels.
    Note: Click Export Data to export the available plots in a .csv file.
