Keysight Technologies N4900 Series
Keysight offers a wide range of serial bit error ratio test (BERT) solutions for R&D and manufacturing. The J-BERT N4903B high-
performance serial BERT is the agship of eysights N4900 serial BERT series. It addresses the needs of R&D and validation teams
who characterize serial I/ ports or ASIs up to 14.2 Gb/s. The data rate can be extended up to 28.4 Gb/s by adding a 21 multiplexer
and demultiplexer with cloc data recovery. Integrated and calibrated jitter sources for jitter tolerance measurements allow designers
to characterize and prove compliance of their receivers jitter tolerance.
eysights N4900 serial BERT series offers ey benets
– Excellent precision and sensitivity for accurate measurements
– hoice of feature set and freuency classes to tailor to test needs and budget
