In Eye/Mask mode, all of the measurements are made on the color grade/gray scale data, with the exception of average optical power and histogram measurements. NRZ, PAM, Advanced Eye measurements are displayed on the Results panel except for Eye Mask measurements which are displayed on the Mask Test panel. The SCPI commands for each type of measurement are located in the following SCPI command nodes:

  • NRZ waveform measurements (:MEAS:EYE)
  • PAM waveform measurements (:MEAS:EYE and :MEAS:EYE:PAM)
  • Advanced Eye measurements (:MEAS:EYE)
  • Eye Mask measurements (:MEAS:MTESt)

Two identical SCPI nodes exist: :EYE and :CGRade. These nodes are equivalent and you can use either one at any time, but it is recommended that you consistently use :EYE. The :CGRade node is provided for legacy reasons and is not shown in the command topics. However, the following two commands are equivalent: :MEASure:EYE:FALLtime and :MEASure:CGRade:FALLtime.

Use the :MEASure:EYE:COMPlete command to set the peak numbers-of-hits required in the color grade database before a color grade measurement is made on the data. Use Eye user measurement commands (:MEASure:EYE:USER) to create custom user-defined measurements that are based on Matlab or Python scripts. When the measurement is created, a button is automatically placed on Eye Mode's User toolbar.
