Perform TDR on Report

The idea behind Time-Domain Reflectometry (TDR) is to excite a structure with a step or impulse function, and inspect the reflections as a function of time. Before you can examine the time domain, you must perform a sweep for a transient or eddy current solution. You can perform TDR on an existing 2D plot by using the Results > Perform TDR on Report command. This opens a Perform TDR On Traces in reports... dialog.

  1. Select the report you want from the list in the dialog.
  2. Specify the input signal as Step or Impulse and give the rise time.
  3. Select the TDR Window type from a drop down list.

Select the 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.

You may choose to specify a window width as a percentage.

If you select the Kaiser function, you can specify a Kaiser number.

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