The Keysight Technologies, Inc. High-
Speed Serial Data Analysis (SDA) software
provides you with a fast and easy way
to pinpoint signal integrity problems
and validate performance for serial
interface designs. Perform mask testing,
characterize serial data streams that
employ embedded clocks, and decode
8b/10b data.
SDA software enables engineers to verify
compliance to computer, communication,
and data communications standards
such as PCI Express^®, Serial ATA, Serial
Attached SCSI (SAS), Fibre Channel, XAUI
and Gigabit Ethernet.
The BER contour feature provides data
valid window measurement capability
with components of noise and jitter. This
allows designers such as memory DDR4
and LPDDR4 to make JEDEC compliance
measurements.
SDA software and the Infiniium
oscilloscopes offer several features to
simplify the validation of serial interface
designs:

recovered clock.

unfolding
The real-time eye display is reconstructed
from all unit intervals in the oscilloscope
memory aligned by the recovered clock.
In this display mode the center screen (or
zero in the time base) corresponds to the
active edge of the recovered clock. Each
signal including channels and functions
can be displayed as a real-time eye.
With the High-Speed SDA software, once
you identify a failure of the eye mask, you
can unfold the eye diagram to show the
specific unit interval that caused the
failure. When used with the 8b/10b
decoding feature you can identify data
dependent errors that result in eye
mask violations caused by Inter-Symbol
Interference (ISI).
