Couplings If Auto Scaling is set to On, the X Width is determined by the trace data
Preset Depends on trace data
State Saved Yes
Min/Max -9.9E+37 / 9.9E+37
Ref Value
Controls the X value of the selected trace at the chosen X Reference Position.

Command
:DISPlay:EVM:WINDow[1]|2|...|6:X[:SCALe]:RLEVel <real>
:DISPlay:EVM:WINDow[1]|2|...|6:X[:SCALe]:RLEVel?
Example
:DISP:EVM:WIND3:X:RLEV 10
set the X ref value of the third window to 10
:DISP:EVM:WIND3:X:RLEV?
query the X ref value of the third window

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.
