## Description

Sets the function N horizontal time scale of the real-time eye display in seconds-per-division.

This command directly affects the real-time eye's horizontal range setting in UI (unit interval) units (see the `:FUNCtion:EYE:UIXRange` command).

To set the horizontal position (center display location), use the `:FUNCtion:EYE:XPOSition` command.

Only the center UI is valid for the recovered clock edge. You can display up to 10 UIs to show context before and after the center UI.
