 {EYE0}

Description

This command allows you to select an eye on PAM4 signals. For NRZ signals, the 0 eye is automatically selected and cannot be changed. The command selects the PAM4 eye on which to perform the :MEASure:EYE:PAM:VECLosure. The query form of the command returns the currently selected eye.

Requires FlexDCA revision A.06.60 and above.

Measurement Identification

Avoid subtle programming errors! To ensure that the correct measurement is installed or queried, always explicitly identify a measurement when installing a measurement or querying a measured value, status, or detail. To identify a measurement, specify the measurement's source waveform (:SOURce child command). With some measurements, you may also need to specify other identifying values. Generally, when selecting a measurement using FlexDCA's GUI, if a dialog appears prompting you to select values, you should explicitly specify these values when remotely identifying the measurement. More information.

For example, to return the status of the measurement, :MEASure:EYE:PAM:VECLosure:EYE:

flex.write(':MEASure:EYE:PAM:VECLosure:EYE:SOURce CHAN1A')
if flex.query(':MEASure:EYE:PAM:VECLosure:EYE:STATus?') == 'CORR';
    measurement = flex.query(':MEASure:EYE:PAM:VECLosure:EYE?')
else:
	details = flex.query(':MEASure:EYE:PAM:VECLosure:EYE:STATus:DETails?')
	reason = flex.query(':MEASure:EYE:PAM:VECLosure:EYE:STATus:REASon?')
