Generally, a higher sweep time leads to more data to be averaged and thus stabilizes
the results. In FFT mode, a higher sweep time means more FFTs are calculated and
combined per bin.
Thus, in the same capture time, the FFT mode with an RMS detector can provide bet-
ter results than an averaged trace.
