## Command Syntax

    :MEASure:EYE:PAM:EWIDth:DEFine:EOPening {ZHITs | PROBability}

## Query Syntax

    :MEASure:EYE:PAM:EWIDth:DEFine:EOPening?

## Description

Selects the method used to determine the eye-opening: zero hits (`ZHITs`) or probability (`PROBabilitly`). If probability is selected, use the `:MEASure:EYE:PAM:EWIDth:DEFine:EOPening:PROBability` child command to enter the probability. The entered measurement-hit probability establishes the contour of an eye's opening. The default value is 1 x 10–18.
