RTB / RTM / RTA - changing the timebase with active FFT


With active FFT it seems that the timebase setting can not be changed. Is there a way to do that?


The timebase is adapted automatically when the frequency parameters of the FFT are changed. This is done to archieve optimized results.

You can change the timebase in indirect way, if you change the span.
Increase the span --> the timebase becomes faster
Decrease the span --> the timebase becomes slower
