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 up and

down direction keys to switch between measurement channels in a specified

step in order to sweep the adjacent channel manually.

 You can modify this parameter using the numeric keys, knob or direction keys.

For more details, please refer to “Parameter Setting”.
