Yes. Look at the Help for Waveform Arithmetic.
At the end you can see an FFT set-up pane that allows start and
end times for the FFT to be set up.

Hi, :
?
May I ask about FFT feature ?
?
If in a waveform viewer, I want to do FFT analysis of a
chosen node, which may has multiple frequency components varying
during whole simulation time interval.
Can it be done to separate the whole simulation time into
several intervals by eg: zoom-in feature, then run the FFT
feature only for the "zoom-in"ed waveform data, to see what's
the freq component in these data ?
I say so, because, some applications , eg: OFDM modulation,
may have the multiple freq components in modulated signal, and
may vary the amplitude depending on transmitted data in
different time interval.
?
It helps to analyze if FFT could do analyzing of separated
time interval in a single waveform.
?
Is this feature supported ?
?
Thank you very much.
Best regards.
