Example:
Manual operation:
CALCulate<n>:STATistics:SCALe:AUTO ONCE
This command initiates an automatic scaling of the diagram (x- and y-axis).
To obtain maximum resolution, the level range is set as a function of the measured
spacing between peak power and the minimum power for the APD measurement and
of the spacing between peak power and mean power for the CCDF measurement. In
addition, the probability scale for the number of test points is adapted.
To get valid results, you have to perform a complete sweep with synchronization to the
end of the auto range process. This is only possible in single sweep mode.

Manual operation:
CALCulate<n>:STATistics:SCALe:X:RANGe <Range>
This command defines the display range of the x-axis for statistical measurements.
The effects are identical to
Y[:SCALe].
