Due to the higher sampling depth of a BERT, the eye contour lines visualize the measured eye at a deeper BER level for more accurate results. Extrapolated eye contour lines display the eye opening for even lower BER levels such as 10-15 reducing the measurement time signi cantly.
08 eysight J-BERT N4903B igh-Performance Serial BERT 7 Gb/s and 12.5 Gb/s - Data Sheet ser Interface Bit recovery mode ption A01 This mode is useful for analyzing non-deterministic traf c. This is helpful when you need to analyze real world traf c for example in a P I Express lin where so-called s ip ordered sets are added unpredictably to avoid I over ow. This simpli es setup by eliminating the need to setup expected data for the error detector.
