:DISPlay:DDEMod:WINDow[1]|2|…|6:X[:SCALe]:RLEVel?
Example
:DISP:DDEM:WIND3:X:RLEV 10
Set the X ref value of the third window to 10
:DISP:DDEM:WIND3:X:RLEV?
Query the X ref value of the third window
Couplings If Auto Scaling is On, the X Reference Value is determined by the trace data
Preset Depends on trace data
State Saved Yes
Min/Max -9.9E+37 / 9.9E+37
Ref Position
Determines the position from which the X scaling is calculated for the selected
trace. It can be set to the left side, center, or right side of the grid.

Auto Scaling
Toggles the Auto Scaling function On or Off.

Command
:DISPlay:DDEMod:WINDow[1]|2|…|6:X[:SCALe]:COUPle 0 | 1 | OFF | ON
:DISPlay:DDEMod:WINDow[1]|2|…|6:X[:SCALe]:COUPle?
Example
:DISP:DDEM:WIND3:X:COUP ON
Do the X auto scale for the third window
:DISP:DDEM:WIND3:X:COUP?
Query the X auto scale state of the third window
Couplings When this parameter is On, pressing the front-panel Restart key activates the scale coupling function,
that automatically determines scale per division and reference values based on the measurement
results. When you set a value to either X Width or Ref Value manually, Auto Scaling is automatically set
to Off
