BERT

The Agilent / Keysight N4903B J-BERT is a high-performance serial BERT with complete jitter tolerance and is ideal for R&D and validation teams characterizing and stressing chips and transceiver modules that have serial I/O ports up to 7 Gb/s, 12.5Gb/s or 14.2 Gb/s. The pattern generator has significantly low jitter and extremely fast transition times producing clean signals that provide accurate characterization and faster test execution.Features：Data rates 150 Mb/s to 7 Gb/s or to 12.5 Gb/s pattern generator and error detector. Option to extended data rate to 14.2 Gb/s for pattern generator.>0.5 UI calibrated, compliant and integrated jitter injection: RJ, RJ-LF, RJ-HF, PJ1, PJ2, SJ, BUJ, ISI, sinusoidal interference, triangular and arbitrary SSC and residual SSCArbitrary SSC profile and extended SSC range to characterize SATA/SAS and USB3 receivers under real-world conditionExcellent signal performance and sensitivityImproved output signal performanceMeasures BER, BERT Scan, TJ with RJ/DJ separation, eye diagram, eye mask, BER contour, automated jitter tolerance, pattern capture, frame error rate (FER), or symbol error rate (SER) coded and retimed data streamsTwo adjustable data outputs with independent PRBS and pattern with 120 block pattern sequencerVariable output levels on trigger and aux data outputsAll options are retrofittable and upgrade from N4903A possibleBuilt-in clock data recovery with tunable and compliant loop bandwidthSupports testing of forwarded clock devices:Halfrate clock with variable duty cycleJitter on clock and dataDelay of jitter between clock and dataPCIe 2.0 compliant jitter injection:LF-RJ and HF-RJdual-tone PJresidual SSCelectrical idle16x FC testing with extended data rate for the pattern generator up to 14.2 Gb/sWider PJ range up to 300 MHz
