:MTESt Scaling Commands

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 boundaries (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 :MEASure:EBOundary:LEFT and :MEASure:EBOundary:RIGHt to set the eye boundaries.

Requires FlexDCA revision A.03.00 and above.
