## Command Syntax

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

Where N identifies a specific differential waveform in the form "<connection1-8>_<ch1|ch3|ch5|ch7>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1|ch3|ch5|ch7>". When two channels are paired to create a differential waveform and a common-mode waveform, the odd-numbered channel is used when specifying the waveform. For example, connection 5 differential waveform 3 (from the pairing of channels 3 and 4) is `DIFF5_3`.

## Query Syntax

    :DIFFN: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 `:DIFF:EYE:WINDow:LEFT` and `:DIFF: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 `:DIFF: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.
