Start Freq Mode
Sets the coupling mode of the start frequency to "Manual" or "Auto". When "Auto" is
selected, the start frequency will automatically couple to the start frequency of the
first range among the currently enabled ranges in the scan table.
Stop Freq
Sets the stop frequency of the current frequency channel.
Remarks:
When you modify the stop frequency, the span and midspan frequency will be
changed.
You can use the numeric keys, the knob, or arrow keys to modify this parameter;
you can also use the touch screen to modify the parameter.

trace data.
Modifying the X-axis scale type will neither restart the scan nor affect the
number of scan points.
