The Agilent Technologies HighSpeed 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. The High-Speed SDA
software, when used with the
Agilent 8000, 54830, 54850, 80000
and 90000 Series Infiniium realtime oscilloscopes, allows you
to perform mask testing, characterize serial data streams that
employ embedded clocks, and
decode 8b/10b data from serial
data streams (54850, 80000 and
90000 Series only). The
High-Speed 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 High-Speed SDA software
and the 8000, 54830, 54850,
80000 or 90000 Series Infiniium
oscilloscopes offer several features to simplify the validation of
serial interface designs:

Easy measurement setup
The High-Speed SDA software
extends the ease-of-use advantages of Agilent’s Infiniium oscilloscopes to the analysis of serial
data. A wizard walks you quickly
through the steps required to
setup and perform a measurement. Intuitive displays and clear
labeling of information make it
easy to comprehend measurement results.
Select signal source
Select clock recovery algorithm
Figure 1. To set up a measurement, the wizard asks you to identify the signal
source and select the clock recovery algorithm.

Mask testing
When used with the Agilent
54850, 80000 or 90000 Series
Infiniium oscilloscopes, masks
are provided for the following
standards:
• PCI Express (2.5 and 5 GSa/s)
• Fibre Channel Electrical
(1.0625, 2.125 and 4.25 Gb/s)
• Serial ATA
• Serial Attached SCSI (SAS)
• XAUI
When performing a mask test,
the High-Speed SDA software
indicates the number of waveforms (acquisitions) tested, the
number of failed waveforms, the
number of unit intervals tested,
and the number of failed unit
intervals. This information helps
determine your level of confidence in meeting a given target
bit error ratio.
Number of failed UIs and total number
of UIs tested are indicated
Figure 3. An example of a mask test on a failing Serial ATA signal. The information
below the mask screen helps you determine the level of confidence in meeting your
desired bit error rate.
