IEEE 802.3 Ethernet Compliance
and Debug Applications
For 86100D DCA-X Oscilloscopes
Data Sheet
Introduction
Easy-to-use oscilloscope application that lets you:
–– Save time in understanding details of standards
–– Reduce your IEEE 802.3 test times from hours to minutes
–– Debug your device using custom configurations
–– Characterize up to 10 lanes in multi-lane devices
The greatly increased worldwide demand for video and data transfer has created new requirements
for network expansion, driving innovative network elements for operation up to 100 Gb/s. New designs
are facing more challenges while transferring these signals on printed circuit boards within hosts and
modules, even for short distances. Measuring the IEEE 802.3 parameters can take a full day when manually
characterized, and recalculating factors and equation-driven limits adds to the time the designer spends on
testing.
Keysight Technologies, Inc. created the N1081A, N1082A, N1083A and N1084A IEEE 802.3 Compliance and
Debug Applications to simplify measuring these transmitter parameters and to obtain full results to test
limits in a few minutes. This will keep you focused on getting your products to market knowing that your
results are built on the heritage and consistency of Keysight measurement technology.

Transform Complexity into Simplicity
Satisfying the comprehensive requirements of the IEEE 802.3 clauses can be very complex. The list of tests and test conditions vary from
clause to clause, and each can be challenging to properly set up. The tests for each IEEE 802.3 clause vary, as do the test limits. An
example of one group of tests from clause 93 is below. The time for your test development team to read and interpret the specification
and then implement that understanding into test plans can take several months of effort.

Hosts and modules have unique interface
connectors and require compliance boards
or test adapters to enable connection
to test equipment. Designers endeavor
to minimize the trace lengths on the
compliance boards and cable lengths.

Debug and Verify Your Designs Quickly and Easily
Select industry-leading
hardware
Configure your oscilloscope for a single
module (as below) or multi-module
(listed in ordering guide). Connect your
device through the recommended phase
trimmers to have access to measurements
with intrinsic jitter as low as 50 fs. For
return loss, also connect the Economy or
Performance Network Analyzer, which are
controlled by the DCA-X for S-parameter
measurements.
Phase trimmers >>
(recommended)
Transmitter
Select desired 10G/25G transmit
clause
The N108xA IEEE 802.3 applications cover
all transmitter tests for 12 clauses and
conveniently organize the tests by clause.
Click on the desired test group, and the
appropriate tests are offered in Select
Tests.

Debug and Verify Your Designs Quickly and Easily (Continued)
Configure your measurements
Customize parameters that are specific
to your setup, such as data rate and
attenuation. Use default values or enter
your own settings including number of
waveforms or patterns taken; type of
pattern; and whether or not to remove the
effects of test cables. Choose Compliance
mode to test within compliance limits
or choose Debug mode to test to your
custom limits and adjust other test
parameters.
Choose from more than 400
tests
The tests required for each of the transmit
and test signal groups are available. You
can click on all tests, a group of tests
or individual tests. The full test name
appears in the test list and is shown in the
test results and reports. A description of
the test and reference to the IEEE 802.3
clauses are shown for each test.

Simply follow the steps and click Run
Tests. The N108xA applications, 86100D
DCA-X and ENA/PNA readily measure
your device.
Obtain concise compliance
reports
Users and customers are interested in
the performance of your devices. Share
a report that shows the test conditions,
summary of pass/fail, summary of all
tests, and details for each test. Many
include the appropriate screen shot of the
measured parameter.

Control your device or other
equipment
The Automation tab lets you enter
commands to control external devices or
equipment, further sequence your tests, or
to control timing.
See device performance in one
view
In a few minutes, you’ll have test results
showing which parameters passed or
failed and the margin compared to limits.
These results will provide immediate
insight into how you’ll need to improve
your design to meet the challenging tests
in the IEEE 802.3 clauses.

More Features to Further Streamline Your Development
Utilize test adapters
Development and characterization of
advanced integrated circuits is timeconsuming and expensive. Designers
utilize test adapters to fully characterize
their parts for use in their own or their
customer’s circuits.
For more information about these
adapters, please visit http://shop.wildertech.com/category_s/42.htm.
…or host and module
compliance boards
By pairing your test adapter or compliance
board with the 86100D, 86108B and
N108xA software, you will have the
simplest and most powerful solution
available to optimize your designs and
offer the best products to your customers.
Phase trimmers and a pair of cables
complement your setup for the most
consistent and accurate measurements.

More Features to Further Streamline Your Development (Continued)
Configure your solution in three
ways
The hardware and software architecture
provides wide flexibility. You may install
the N108xA on the mainframe, which
includes FlexDCA, or the N108xA on your
PC, controlling FlexDCA on the DCA, or
install both N1010A FlexDCA and N108xA on
your PC. This lets you use your PC for more
processing power and other applications,
or you can have all measurement capability
consolidated into a compact solution. The
ENA/PNA is controlled by the N108xA via the
PC or the DCA.
Conveniently de-skew your
cables
Skew between the true and complement
signals will often degrade your measured
performance. While you need to
characterize performance with the DUT
skew included, the N108xA guides you to
quickly de-skew your test cables using
phase trimmers or to de-skew the N1045A
or 86118A-H01 remote heads for best
results.
