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.

802.3bm-2015 specification.
