N1014A SFF-8431 (SFP+)


Easy-to-use oscilloscope application that lets you:

  • Save time in understanding details of standards
  • Reduce your SFP+ test times from hours to minutes
  • Debug your device using custom configurations

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 SFF-8431 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 N1014A SFF-8431 Compliance and Debug Application 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 broad requirements of the SFF-8431 Specifications can be very complex. The data rate for each test group varies based on which standard is being addressed in the product design. The tests between each SFF-8431 group vary, as do the test limits. An example of one group of tests 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.

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 N1014A for S-parameter measurements.

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 Normal mode to test within compliance limits or choose Debug mode to test to your custom limits and adjust other test parameters.

Select any SFP+ transmit interface

The N1014A SFF-8431 Compliance and Debug Application covers all host and module transmitter tests as well as verification of the test signals for receiver compliance. Click on the desired test group, and the appropriate tests are offered in Select Tests.

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.

Choose from more than 70 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 SFF-8431 Specifications are shown for each test. You may also measure TWDP by interfacing with your MATLAB script.

Measure challenging parameters fast

Simply follow the steps and click Run Tests. The N1014A software will control the 86100D DCA-X, N109X DCA-M, and/or ENA/PNA/TDR and readily measure your device.

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 SFF-8431 Specifications.

Utilize compliance boards

Development and characterization of advanced integrated circuits is time-consuming and expensive. Designers utilize test adapters to fully characterize their parts for use in their or their customer’s circuits. For more information on these adapters, please visit

Configure your solution in three ways

The hardware and software architecture provides wide flexibility. You may install the N1014A on the mainframe, which includes FlexDCA, or the N1014A on your PC, controlling FlexDCA on the DCA, or install both N1010A FlexDCA and N1014A 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 N1014A 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 N1014A guides you to quickly de-skew your test cables using phase trimmers or to de-skew the 86118A-H01 remote heads for best results.
