Keysight-Agilent N4903A
The newest member of Agilent’s N4900 serial
BERT series is the powerful J-BERT N4903A HighPerformance 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.

Description
Keysight-Agilent N4903A
The Keysight-Agilent N4903A High-Performance Serial
BERT provides the only complete jitter tolerance
test. 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 or 12.5 Gb/s. It can characterize a
receiver’s jitter tolerance and prove its compliance to today’s most popular standards, such as
PCI Express, SATA, Fibre Channel, Fully Buffered
DIMM, CEI, 10 GbE/ XAUI, XFP/XFI, SFP+.
Accurate characterization is achieved with clean
signals from the pattern generator, which features
exceptionally low jitter and extremely fast transition times. Test set-up time is reduced significantly, because the J-BERT N4903A matches most
recent serial bus standards optimally:
• Undeterministic patterns can now be analyzed
with the bit recovery mode.
• A pattern sequencer helps to set up training
sequences quickly, to get complex devices into
loop-back test mode.
• Reference clocks can be provided by the subrate
clock outputs, which can generate any ratio of
clock to data rate.
• All I/Os are differential and a built-in CDR
allows testing of clockless interfaces.
