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.

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.
