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.
