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.

Improving averaging results
