Perform TDR on Report

You can perform TDR on an existing 2D plot by using the Results > Perform TDR on Report command. You can perform TDR on an existing 3D plot by using the HFSS 3D Layout > Results > Perform TDR on Report command. This opens a Perform TDR on Traces in reports dialog box.

1. Select the report you want from the list in the dialog box.
2. Specify the input signal as Step or Impulse.
3. Set the Rise Time.
4. In the Type drop-down menu, select which window type to apply.

   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.

5. To specify a window width, enter a percentage into the Width (%) field.
6. If you select the Kaiser function, specify a number in the Kaiser Parameter.

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