I am wondering how do we analyze BER using Bathtub. I have attached a chart and I need to analyze it. Any explanation please to understand the BER plots on the Bathtub.
this looks more like the Grand Canyon than a bathtub 1e-250 ?
It appears to be a low noise with an infinite slope on BER for the comparator or logic device that shows the symmetry or threshold error vs Vi in terms of a transition from either logic level.
Very strange.
U2.2p is actually pin number 2 positive end of the differential signal at the device U2. I am running some gigabit transceiver cannel simulations and I got the BER plotted in Bathtub which I am not able to get.
I am familiar with analyzing BER curves, Window Margin statistics, Phase Margin Plots and Eye pattern margins, but I have no idea what equipment you have and what you want to measure.
Please explain in detail your issues, what you can /cannot do.
. Your plots show extremely high SNR with threshold-related margins.
