Junkosha’s Method of Calculating Degree of Eye Pattern

To measure pulse wave transmission characteristics, an experimental tool called "eye pattern" is observed. Upon balanced transmission, skew (variability of propagation delay time) between the signal cables will become one of the causes of deterioration of the jitter. Our MWX6 series are designed and manufactured taking the above into consideration.
