To configure the spectrum of FFT analysis
By default, a suitable frequency range for the expected horizontal values according to
the resolution bandwidth is selected, in respect to performance and precision. Span
and RBW settings are coupled. If a more precise evaluation is required, for example for
postprocessing in a different application, disable the coupling and change the fre-
quency ranges and resolution bandwidth values as required.
1. Open [FFT] > "FFT setup".
The "FFT" dialog opens.
2. In the "Setup" tab, tap the "Frequency axis" button to select the type of scaling you
want to use: linear or logarithmic.
3. Disable the "Span/RBW coupling".
4. Specify the frequency range you want to display using one of the following meth-
ods:
● Enter a "Center frequency" and a "Frequency span" that define the spectrum.
