The newest member of Agilent’s N4900 serial
BERT series is the powerful J-BERT N4903A
High-Performance Serial BERT. It 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 toler-
ance tests integrated in a high-performance BERT.
The N4906B serial BERT offers an economic BERT
solution for manufacturing and telecom device
testing.
