To determine the step size, select the parameter Step Linear/Step Logarithmic .
"Linear" Takes the frequency value entered as absolute value in Hz.
"Logarithmic" Takes the value entered as a logarithmic value, i.e. as a constant
fraction of the current frequency in %.
Remote command:
RF frequency sweep:

on page 955
Dwell Time
Defines the duration of the individual sweep steps.
Note: In case of considerable overrun conditions, the R&S SMM100A turns off the
sweep mode.
