The T1 values are vertical and horizontal values associated with the leftmost
crossing point. These areas are used to establish the following directions:
H TCross1
, the horizontal mean of the left crossing point at TCross
mean
H TCross1
, the horizontal standard deviation of the left crossing point
sigma
at TCross
1
H TCross1
, the horizontal peak-to-peak deviation of the left crossing point
p-p
at TCross
1
H PCross1
, the vertical mean of the left crossing point at PCross
mean
The T2 values are vertical and horizontal values associated with the rightmost
crossing point. These areas are used to establish the following directions:
H TCross2
, the horizontal mean of the right crossing point at TCross
mean
H TCross2
, the horizontal standard deviation of the right crossing point
sigma
at TCross
2
H TCross2
, the horizontal peak-to-peak deviation of the right crossing point
p-p
at TCross
2
The duty cycle distortion (DCD) values are horizontal values associated with the
rightmost crossing point at 50% of the eye height. These areas are used to
establish the DCD , the horizontal peak-to-peak deviation of the left crossing
p-p
point at half the height of the eye.
