CF Step
Set the step of center frequency. Changing the center frequency in a fixed step
continuously switches the channel to be measured.
Key Points:

The CF step can be set in "Manual" or "Auto" mode. In Auto mode, the CF step
is 1/10 of the span in Non-zero span mode or equals the RBW while in Zero
span mode; in Manual mode, you can set the step using the numeric keys.

After you set an appropriate CF step and select Center Freq , use the up and
down arrow keys to switch between measurement channels in a specified
step in order to sweep the adjacent channel manually.

You can use the numeric keys, the knob, or the arrow keys to modify the
parameter. For more details, please refer to
"Parameter Setting ".
