Keysight N8841A

CAUI-4 Electrical Performance Validation and Conformance Software

For Infiniium Oscilloscopes

Data Sheet

Easy and Accurate 100 Gb/s Four Lane Attachment Unit Interface (CAUI-4) Ethernet Transmitter Design Validation and Debug

The Keysight Technologies N8841A CAUI-4 Ethernet electrical performance validation and conformance software for Infiniium oscilloscopes provides you with an easy and accurate way to verify and debug your CAUI-4 Ethernet designs. The Ethernet electrical test software allows you to 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.

The N8841A CAUI-4 Ethernet compliance software performs a wide range of electrical tests required to meet the IEEE 802.3bm-2015 Ethernet 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 N8841A CAUI-4 Ethernet compliance software helps you execute a wide subset of the conformance tests that can be measured with an oscilloscope.

Features

The N8841A CAUI-4 Ethernet electrical test software offers several features to simplify the validation of Ethernet designs:

• Setup wizard for quick and clear setup, configuration and test
• Wide range of CAUI-4 Ethernet electrical tests enabling standards conformance
• Accurate and repeatable results with Keysight Infiniium oscilloscopes
• Automated reporting in a comprehensive HTML format with margin analysis

With the CAUI-4 Ethernet electrical test software , you can use the same oscilloscope you use for everyday debugging to perform automated testing and margin analysis based on the IEEE 802.3bm-2015 standard.

N8841A CAUI-4 Compliance Application Software Saves You Time

The CAUI-4 Ethernet electrical test software saves you time by setting the stage for automatic execution of CAUI-4 electrical tests. Part of the difficulty of performing electrical tests for Ethernet transmitters is 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 Ethernet electrical test software does much of this work for you.

The CAUI-4 Ethernet electrical test software automatically configures the oscilloscope for each test, and it provides an informative results report that includes margin analysis indicating how close your product is to passing or failing that specification.

Easy test definition

The CAUI-4 Ethernet electrical test software extends the ease-of-use advantages of Keysight’s Infiniium oscilloscopes to testing CAUI-4 designs. The Keysight automated test engine quickly walks you through the steps required to define the tests you want to make, sets up the tests, performs the tests, and gives you the test results. A setup page enables you to quickly make decisions from the outset regarding the choice of tests and perform functions that affect the testing task. 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.

Configurability and Guided Connections

The N8841A CAUI-4 Ethernet electrical test software provides flexibility in your test setup. It guides you to making connection changes with hookup diagrams when the tests you select require it. SMA cables or probes may be required to connect the device under test to the oscilloscope. See ordering information for more details.

In addition to providing you with measurement results, the CAUI-4 Ethernet electrical test software provides a report format that shows you not only where your product passes or fails, but also reports 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 CAUI-4 specification.

Switch Matrix – Support for Multi-Lane Channels

The Keysight switch matrix software option for the compliance application, used together with switch matrix hardware, enables fully-automated testing for multi-lane digital bus interfaces.

The benefits of this automated switching solution include:

• Eliminate reconnections, which saves time and reduces errors through automating test setup for each lane of a multi-lane bus.
• Maintain accuracy with the use of unique N2809A PrecisionProbe or N5465A InfiniiSim features to compensate for switch path losses and skew.
• Customize testing by using remote programming interface and the N5467A user-defined application tool for device control, instrument control and test customization.
