A-17
*7: RJ (rms), PJ (p-p), DDJ (p-p), DCD, ISI (p-p). DDPWS and PJ
Frequency can be measured when Sampling Mode is Advanced Jitter.
*8: BER specified in TJ Measurement BER in the setting items
*9: Impossible to measure with differential signals

“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.
“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
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.
