## Command Syntax

    :MTEStN:ALIGnment:Y:METHod {DISPlay | EWINdow}

Where N identifies a specific mask and must be a value from 1 to 16 {1:16}. For example, `:MTESt2` selects mask 2.

## Query Syntax

    :MTEStN:ALIGnment:Y:METHod?

## Description

Specifies the method used to align the mask's Y-axis. It ensures that the mask will be properly adjusted on the display. Alignment mode needs to be specified for optical NRZ masks. Use the `:MTESt:ALIGnment:Y` command to select automatic or manual mask scaling.

`DISPlay`
  Aligns the mask's Y axis using the Vbase and Vtop of the eye diagram. This can be used for all mask tests.
`EWINdow`
  Align the Y axis to the eye window (one and zero logic levels). This argument applies to optical NRZ mask. It is typically used to align 10 GB Ethernet masks. This alignment mode does not apply to fixed-voltage masks. Use the Eye Window Configuration Commands to specify the eye window.
