<module-index>/<port-index> PP_EYEREAD [<serdes_index>, <column_index>] ?

Description

Read a single column of a measured BER eye on a 25G SerDes. Every readout also returns the resolution (x,y) and the number of valid columns (used to facilitate reading out the eye while it is being measured). Note that the columns of the eye-data will be measured in the order: xres-1, xres-2, xres-3, … 0. The values show the number of bit errors measured out of a total of 1M bits at each of the individual sampling points (x=timeaxis, y = 0/1 threshold).

Parameters

  1. x_resolution: integer, x resolution, y resolution, number of valid columns, and the number of bit errors measured out of a total of 1M bits at each of the individual sampling points (x=timeaxis, y = 0/1 threshold).

  2. y_resolution: integer, x resolution, y resolution, number of valid columns, and the number of bit errors measured out of a total of 1M bits at each of the individual sampling points (x=timeaxis, y = 0/1 threshold).

  3. valid_column_count: integer, x resolution, y resolution, number of valid columns, and the number of bit errors measured out of a total of 1M bits at each of the individual sampling points (x=timeaxis, y = 0/1 threshold).

  4. values: integer list, x resolution, y resolution, number of valid columns, and the number of bit errors measured out of a total of 1M bits at each of the individual sampling points (x=timeaxis, y = 0/1 threshold).
