:LTESt:MEASure:EYE:LOCation:FREGion

Command Syntax

:LTESt:MEASure:EYE:LOCation{1:32}:FREGion {INSide | OUTSide | ALWays| NEVer}

Query Syntax

:LTESt:MEASure:EYE:LOCation{1:32}:FREGion?

Description

Defines when to fail an eye diagram measurement limit test in Eye/Mask mode. The eye measurement is identified by a number, from 1 to 32, that is appended to the :LOCation portion of the command. Refer to the :MEASure:EYE:LOCation:STATe command to learn how to identify the measurement and to turn the measurement limit test on or off.

INSide

A measurement is counted as a failure if it is within the lower and upper limits, which are set by the :LLIMit and :ULIMit sibling commands.

OUTSide

A measurement is counted as a failure when the measurement results exceed the parameters set by :LLIMit and :ULIMit sibling commands.

ALWays

A measurement is counted as a failure every time the measurement is executed, and the parameters set by the :LLIMit and :ULIMit sibling commands are ignored.

NEVer

Logs the action each time the measurement is executed and can be used to monitor measurements. For example, you can use NEVer to track a measurement trend during an environmental test while running a measurement for a long time as the temperature or humidity is changed. Each time the measurement is executed, the results can be logged as determined by the fail action set with the LTESt:MEASure:SIMage:STATe, LTESt:MEASure:SSUMary:STATe, or LTESt:MEASure:SWAVeform:STATe commands. You can also use NEVer to observe one measurement but determine a failure from a different measurement.

Use the following sibling commands to configure the measurement:

• :FAILures defines the number of failures for stopping a limit test
• :LLIMit defines the lower limit for failing a measurement
• :ULIMit defines the upper limit for failing a measurement
• :UPACtion selects an action if the measurement cannot be performed
