N6467A BroadR-Reach Automotive Ethernet Electrical Compliance Application

Data Sheets

The Keysight Technologies, Inc. N6467A/B 802.3bw and automotive electrical performance validation and conformance software for Infiniium oscilloscopes provides you with an easy and accurate way to verify and debug your automotive Ethernet designs. The Ethernet electrical test software lets you automatically execute Ethernet physical-layer (PHY) electrical tests and displays the results in a flexible report format. In addition to the measurement data, the report provides a margin analysis that shows how closely your device passed or failed each test.

To make automotive Ethernet measurements with the N6467A/B Ethernet electrical test software, you may also need the Keysight N5395C Ethernet electrical conformance test fixture. The optional fixture is only needed when connecting with an RJ-45 cable from the customer’s device, otherwise SMA cables are used to connect directly to the oscilloscope. IEEE 802.3bw does not specify a connector, users may have different means to connect D+ and D- signals to the oscilloscope. For DUTs that use standard RJ-45 Ethernet connections, Keysight’s E5395C Ethernet compliance test fixture can be used for differential signal breakout. Alternatively, a differential probe or SMA cables can be used to access D+ and D- signals.

The N6467A/B Ethernet electrical test software performs a wide range of electrical tests required to meet the 802.3bw as well as BroadR-Reach electrical specifications. To meet signal quality requirements, your product must successfully pass conformance testing based on these specifications. Performing these tests gives you confidence in your design. The N6467A/B electrical test software helps you execute a wide subset of the conformance tests that can be measured with an oscilloscope.

Features

The N6467A/B electrical performance validation and conformance software offers several features to simplify the validation of automotive Ethernet designs:

  • Setup wizard for quick and clear setup, configuration and test
  • Wide range of 802.3bw tests enabling standards conformance
  • Accurate and repeatable results with Keysight Infiniium oscilloscopes
  • Automated reporting in a comprehensive HTML format with margin analysis

With the N6467A/B electrical test software, you can use the same oscilloscope you use for everyday debugging to perform automated testing and margin analysis based on 802.3bw and BroadR-Reach standards.

N6467A/B software saves you time

The N6467A/B electrical test software saves you time by setting the stage for automatic execution of 802.3bw and BroadR-Reach electrical tests. Some of the difficulties of performing electrical tests for 802.3bw and/or BroadR-Reach are properly connecting to the oscilloscope, loading the proper setup files, and then analyzing the measured results by comparing them to limits published in the specification. The N6467A/B electrical test software does much of this work for you.

The N6467A/B electrical test software automatically configures the oscilloscope for each test and provides an informative results report that includes margin analysis indicating how close your product is to passing or failing that specification. See Table 2 for a complete list of the measurements made by the N6467A/B test software.

Easy test definition

The N6467A/B electrical test software extends the ease-of-use advantages of Keysight’s Infiniium oscilloscopes to testing 100BASE-T1 designs. The Keysight automated test engine quickly walks you through the steps required to define the tests you want to make, set up the tests, perform the tests, and view the results. A setup page lets you quickly make decisions from the outset regarding the choice of tests and perform functions that affect the testing. The test selections available in the following steps are then filtered according to the choices made in the setup page. While selecting tests, you can select a category of tests all at once or specify individual tests. You can save tests and configurations as project files and recall them later for quick testing and review of previous test results. Straightforward menus let you perform tests with a minimum amount of mouse clicks.

N6467A/B software saves you time

View all of the tests in the GUI under selected tests

  • Setup wizard for quick and clear setup, configuration and test
  • Clearly see all the available tests
  • Run single or multiple tests based on your needs
  • When test is highlighted, it will show description of test along with pass limits
  • Accurate and repeatable results with Keysight Infiniium oscilloscopes
  • Automated reporting in a comprehensive HTML format with margin analysis

Configurability and guided connections

In addition to giving you measurement results, the N6467A/B electrical test software also provides a report format that shows you not only where your product passes or fails but also how close you are to the limits specified for a particular test. You can select the margin test report parameter, which means you can specify the level at which warnings are issued to alert you to electrical tests where your product is operating close to the official test limit defined by the IEEE 802.3bw specification.

Extensibility

You may add additional custom tests or steps to your application using the N5467B User Defined Application (UDA) development tool (www.keysight.com/find/uda). Use UDA to develop functional “Add-Ins” that you can plug into your application.:

Add-Ins may be designed as:

  • Complete custom tests (with configuration variables and connection prompts)
  • Any custom steps such as pre or post processing scripts, external instrument control and your own device control

Automation

You can completely automate execution of your application’s tests and Add-Ins from a separate PC using the included N5452A Remote Interface feature (download free toolkit from www.keysight.com/find/scope-apps-sw). You can even create and execute automation scripts right inside the application using a convenient built-in client.
