CF Step
Changes the step size for the center frequency. Changing the center frequency by a
constant step-size value switches the channel to be measured continuously.
Remarks:
 Set a proper CF step value, and then select the center frequency. Use the
Up/Down arrow key to switch the measurement channel at a fixed step size.
Thus, the instrument can sweep the adjacent channels manually.
