Can you change the number of frequency points it uses to do the time 
domain plot? I assume it's measuring at a series of frequency steps and 
then doing a transform to time domain.

If you don't need as many points of resolution, it can go faster.  If 
you keep the step spacing the same, and use fewer points, the time 
resolution will be worse, but the maximum unambiguous distance will be 
the same.  If you keep the total frequency span the same, the resolution 
stays fine, but you bring the unambiguous distance in.
