Center
Opens an edit dialog box to enter the center frequency. The allowed range of values
for the center frequency depends on the frequency span.

CF Stepsize
Opens a submenu to set the step size of the center frequency.
The step size defines the value by which the center frequency is increased or
decreased when the arrow keys are pressed. When you use the rotary knob the center
frequency changes in steps of 10% of the "Center Frequency Stepsize".
The step size can be set to a fraction of the span (span > 0) or a fraction of the resolu-
tion bandwidth (span = 0) or it can be set to a fixed value manually.
Apart from the =Center, =Marker and Manual softkeys, the other softkeys are dis-
played depending on the selected frequency span.
0.1*Span (span > 0) ← CF Stepsize
Sets the step size for the center frequency to 10 % of the span.
Remote command:
FREQ:CENT:STEP:LINK SPAN, see [SENSe:]FREQuency:CENTer:STEP:LINK

0.1*RBW (span > 0) ← CF Stepsize
Sets the step size for the center frequency to 10 % of the resolution bandwidth.
This is the default setting.
