The J-BERT N4903A addresses the needs of R&D and validation teams to characterize serial I/O ports or ASICs up to 12.5 Gb/s. Integrated and calibrated jitter sources for jitter tolerance measurements also allow designers to characterize and prove compliance of their receiver’s jitter tolerance. The J-BERT N4903A High-Performance Serial BERT is the ideal choice for characterization. It offers fully integrated and calibrated jitter tolerance tests integrated in a high-performance BERT.

The J-BERT N4903A High-Performance Serial BERT provides the only complete jitter tolerance test. It is the ideal choice for R&D and validation teams characterizing and stressing chips and transceiver modules that have serial I/O ports up to 7 Gb/s or 12.5 Gb/s. It can characterize a receiver’s jitter tolerance and prove its compliance to today’s most popular standards, such as PCI Express, SATA, Fibre Channel, Fully Buffered DIMM, CEI, 10 GbE/ XAUI, XFP/XFI, SFP+.
