Flag/report this product
Itís official: serial fabrics are replacing parallel buses. And myriad small form factors like PC/104, ETX Express, AMC, PMC, and others are all moving in this direction ñ not only for inter-board connectivity, but also for high-speed I/O to sensors and LANs. Trouble is, high speed encoding such as 8B/10B or poorly terminated lines can inject errors. Thatís bad, because bit-rate errors force retransmits and lost data, and they choke performance. Agilentís N4903A serial bit error ratio tester can help, and it also performs jitter-tolerance testing, J-BERT, at rates up to a whopping 12.5 Gbps. With serial lines expected to blow past 5 Gbps in the next 12 months, this unit is a must-have. It provides built-in and calibrated jitter composition for stressed eye testing of receivers with sources for PJ, RJ, BUJ, ISI, and sinusoidal interference. Complex serial patterns can be analyzed, and multiple line training sequences can be simulated. Thereís built-in clock data recovery and even spread-spectrum clocking. Accurate characterization is evidenced by supporting and displaying the cleanest eye diagrams, with 20 ps transition times and 50 mV analyzer sensitivity. All popular bus standards are supported, and more, including: PCI Express, SATA, Fibre Channel, FB-DIMM, CEI, GbE, and XFP. Agilent www.agilent.com RSC# 30432
