Compliance
In compliance, gain confidence by
tapping into Agilent's expertise as
an active participant in the relevant
standards bodies. Our solutions
include compliance tests certified by
the governing bodies responsible for
numerous interfaces. What's more,
these are the same instruments
used by independent test labs--so
you can trust your results. Obtain
greater accuracy by removing channel
artifacts. Change the measurement
parameters to learn sensitivities
and distributions, and to understand
marginal performance. Maximize
design margins by correlating
measurement results in the time and
frequency domains.
Our instruments include capabilities
such as the intuitive creation of
mask templates, which accelerates
the creation of pass/fail criteria
for interconnects. Specialized test
suites for high-speed protocols help
you make an efficient transition
from prototype to production. Our
use of familiar nomenclature and
features enables faster throughput in
manufacturing test.
You can begin compliance testing
before committing the first prototype
with the ADS Compliance Design
Kits, which are free add-ons that
cover standards such as DDR2 and
DDR3. The design kits can easily be
customized to other protocols and
standards using industry-standard
tools such as Excel, XML and C++.

Signal Integrity
At this stage of the life cycle it can
also be useful to address underlying
SI issues. Save time and reduce
costs with SI-specific solutions
such as InfiniiSim for Agilent
Infiniium oscilloscopes. Also take
your measurement science further
and increase your design margins
by utilizing Agilent's exclusive
PrecisionProbe software.
Whether you handle SI analysis as
an independent topic or a deeply
interwoven part of digital design,
Agilent offers today's most powerful
range of SI tools. Leverage your
own multi-domain expertise through
solutions that provide complete
characterization in the time, frequency
and simulation domains. Solve
your toughest problems--in a new
standard or a new product--with
advanced toolsets such as our SI
portfolio for high-speed digital design.
If your organization has a dedicated
SI lab, enhance its capabilities with
product platforms that are designed to
support the latest design, simulation
and measurement technologies.
We're constantly leveraging our work
with SI thought leaders, industry
standards committees and our own
design experts to evolve and improve
the measurement and simulation
capabilities in our solutions.
