Agilent N4903B

J-BERT high-performance serial BERT up to 7 Gb/s and 12.5 Gb/s with complete jitter tolerance

The J-BERT N4903B high-performance serial BERT provides the most complete jitter tolerance test for embedded and forward clocked devices.

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, 12.5Gb/s or 14.2 Gb/s. It can characterize a receiver's jitter tolerance and is designed to prove compliance to today's most popular serial bus standards.


    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 SSC

    Excellent signal performance and sensitivity

    Built-in clock data recovery with tunable and compliant loop bandwidth

    Half-rate clocking with variable duty cycle for forwarded clocked devices

    Measures BER, BERT Scan, TJ with RJ/DJ separation, eye diagram, eye mask, BER contour, automated jitter tolerance, pattern capture symbol error ratio (SER) of coded and retimed data streams

    Two adjustable data outputs with independent PRBS and pattern with 60 block pattern sequencer

    All options are retrofittable and upgrade from N4903A possible
