HP / Keysight / Agilent N4903B - Bit Error Rate Testers

• 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, frame error rate (FER), or symbol error rate (SER) coded and retimed data streams
• Two adjustable data outputs with independent PRBS and pattern with 120 block pattern sequencer
• All options are retrofittable and upgrade from N4903A possible

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

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, such as:
