13 Modulation Accuracy (Composite EVM) Measurement
AMPTD Y Scale
Auto Scaling: I/Q Error View – Phase Error Window
When Auto Scaling is On, pressing the Restart front-panel key automatically displays the scale per division
and reference value results for the vertical axis in the phase error window.
Key Path
AMPTD Y Scale
Mode
WCDMA
Remote Command
:DISPlay:RHO:VIEW2:WINDow3:TRACe:Y[:SCALe]:COUPle 0|1|OFF|ON
:DISPlay:RHO:VIEW2:WINDow3:TRACe:Y[:SCALe]:COUPle?
Example
DISP:RHO:VIEW2:WIND3:TRAC:Y:COUP ON
DISP:RHO:VIEW2:WIND3:TRAC:Y:COUP?
Notes
When this parameter is set to 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 Scale/Div or Ref Value manually, Auto Scaling
is automatically set to Off.
