Figure B- 2: Eye-diagram and optical values
The P values include the mean and standard deviation of the vertical location of
PTop and PBase. These areas are used with a specified sample size to statisti-
cally measure the following values:
HPTopmean, the mean value of PTop
HPTopsigma, the standard deviation of PTop
HPToppk-pk, The vertical peak-to-peak deviation of PTop
HPBasemean, the mean value of PBase within the Eye Aperture1
HPBasesigma, the standard deviation of PBase within the Eye Aperture1
HPBasepk-pk, the vertical peak-to-peak deviation of PBase
1The Eye Aperture defaults to the center 20% of the interval from TCross1to TCross2.
