frequency as percentage of the resolution bandwidth (see CF Stepsize).
c) Press the =Center softkey to set the step size to the value of the center fre-
quency and remove the dependency of the step size to span or resolution
bandwidth.
d) Press the =Marker softkey to set the step size to the value of the marker and
