## Command Syntax

    :FUNCtionN:EYE:WINDow:METHod {EOPening | CLOCk}

Where N identifies one of sixty four {1:64} math functions that you can create. For example, `:FUNCtion2`.

## Query Syntax

    :FUNCtionN:EYE:WINDow:METHod?

## Description

This command specifies how the eye window used for measurements is determined:

- `EOPening` — Measures within an eye window defined by left and right opening locations.

  Use the `:FUNCtion:EYE:WINDow:LEFT` and `:FUNCtion:EYE:WINDow:RIGHt` commands to specify the left and right opening location values. The default values are 40% (left) and 60% (right) which identifies the central 20% of symbol period.

- `CLOCk` — Measures within an eye window that is a width percentage at the location of the recovered clock edge.

  Use the `:FUNCtion:EYE:WINDow:WIDTh` command to specify the width percentage value.

This command is equivalent to the settings in the Eye tab of the Configure Measurements dialog box.
