FFT Conditions (FFT Setup)

Configure the time window and how to display FFT waveforms (normal, peak hold, or average).
On models with user-defined computation (option), you can also select the spectrum to analyze.

Source unit:

There is no source unit when the LinearScale unit or Math unit is not set.

When the source unit is up to two characters in length, the source unit is used.

When the source unit is more than two characters in length, "EU" is used.
