X-Axis
Defines the scaling settings for signal level values.
Ref Level ← X-Axis
Defines the reference level for the signal levels in the currently active unit (dBm, dBµV,
etc.).
For the APD function this value corresponds to the right diagram border. For the CCDF
function there is no direct representation of this value on the diagram as the x-axis is
scaled relatively to the measured mean power.
Remote command:
CALCulate<n>:STATistics:SCALe:X:RLEVel
on page 972
Range ← X-Axis
Defines the level range in dB to be evaluated by the statistics measurement.
Remote command:
CALCulate<n>:STATistics:SCALe:X:RANGe
on page 972
Shifting the Display (Offset) ← X-Axis
Defines an arithmetic level offset. This offset is added to the measured level irrespec-
tive of the selected unit. The scaling of the x-axis is changed accordingly. The setting
range is ±200 dB in 0.1 dB steps.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RLEVel:OFFSet
on page 1040
Y-Axis
Defines the scaling settings for the probability distribution.
Y-Unit ← Y-Axis
Defines the scaling type of the y-axis as either percentage or absolute. The default
value is absolute scaling.
Remote command:
CALCulate<n>:STATistics:SCALe:Y:UNIT
on page 973
Y-Max/ Y-Min ← Y-Axis
Defines the upper (max) and lower (min) limit of the displayed probability range. Values
on the y-axis are normalized which means that the maximum value is 1.0. The mini-
mum value must be in the range:
1E-9 < Y-Min < 0.1
The distance between "Y-Max" and "Y-Min" must be at least one decade.
Remote command:
CALCulate<n>:STATistics:SCALe:Y:UPPer

CALCulate<n>:STATistics:SCALe:Y:LOWer
on page 973
Default Settings
Resets the x- and y-axis scalings to their preset values.
