Energy Distribution - Study

After plotting the energy contribution curves, perform a Partial sum, Modify energy, or Energy overlay response study.

Frequency range
Indicates the available range, based on the frequencies that your energy distribution analysis has performed.
Using the From and To fields, you can customize the frequency range.
The response study type.
Partial sum - Select energy distribution to exclude from the total system energy, with an optional percentage to exclude.
% to exclude
Optional field that allows you to exclude a percentage of the energy distribution from the total system energy.
You can also filter energy contributors to a smaller set by clicking the Filter Contributors dialog icon, .
Select contributors to
Select the energy distribution that you want to exclude or include in the response study.
  • Click to select the entire list of contributors.
  • Click to deselect your current selections.
  • Click energy distribution for the unselected energy distribution in the list.
Show difference curve as
Shows a difference curve between the original energy distribution analysis response and the Partial sum or the Modified energy energy distribution analysis response curves.
% of response - The difference curve shows the difference as a percentage of the original energy distribution analysis response.
Scale same as response - The difference curve shows the difference using the same scale as used in the response plot.
Display Options
Use the Display Options dialog to further customize the plot.
Displays the response study plot once your selections are complete.
