Bridging the Gap Between BER and Eye Diagrams

AbstractBer and Eye Diagrams: Why Neither Is A Complete DepictionIntroducing Ber ContourConsiderationsWhat Ber Contour Can Show YouConclusionMost communication links are ultimately judged on their Bit Error Rate (BER) per-formance – how many bits arrive at their destination in error. Like a test at school, a BER tester (BERT) will tell you the link''s test score, whether 9 out of 10, or 1 out of 10. Unfortunately, this doesn''t tell you qualitative information on why that score was achiev...See more on tek.comteardownit.com
