Center Frequency
Defines the center frequency of the signal in Hertz.
The allowed range of values for the center frequency depends on the frequency span.

Span
Defines the frequency span. The center frequency is kept constant. The following

Remote command:
Frequency Axis Scaling
Switches between linear and logarithmic scaling for the frequency axis.
By default, the frequency axis has linear scaling. Logarithmic scaling of the frequency
axis, however, is common for measurements over large frequency ranges as it enhan-
ces the resolution of the lower frequencies. On the other hand, high frequencies get
more crowded and become harder to distinguish.

Full Span
Sets the span to the full frequency range of the R&S
FSV/A specified in the data sheet.
This setting is useful for overview measurements.
