Sample Timing “Track to Middle EyeTiming”:
The phase of Middle EYE is the reference
“Independent Timing”: The phases of Upper, Middle and Lower are
independent reference in each other.
Eye Center Type “Maximum Eye Width”: The center of the eye opening at the amplitude
where the Eye Width is the maximum is the
reference.
“Maximum Eye Height”: The phase where Eye Height becomes maximum
is the reference.
Peak Power
Hit Ratio
Sets the threshold for determining the Peak Power by the ratio to the
number of samples in 1 UI.
Pmax (Maximum Power): Position of the ratio specified to the number of
samples from the maximum value of the waveform
Pmin (Minimum Power): Position of the ratio specified to the number of
samples from the minimum value of the waveform
Peak Power: Difference between Pmax and Pmin
If 0 is specified, the difference between maximum and minimum values of
the waveform is considered Peak Power.
*10: Items 1 to 4 are available with Version 5. Items 1 to 32 are available
with Version 6 or later.
*11: Available when MP2110A-095 is installed.
