HI RANJEET
i see it means you have uploaded the screenshots for two different scenarios..but in that case it would definitely show some variation in the results because you are using it in two different cases here…it would be more convenient if u choose same design and check the results using the two case:
one in which you directly use 3r regenerator
two in which you connect sequence and pulses directly to the eye diagram analyser.
I hope it will be more clear that way..
Thanks & regards
