Agilent Technologies’ New Serial Data Equalization Software Enables Oscilloscope Users to Test High-Speed Serial Designs


SANTA CLARA, Calif., Agilent Technologies Inc. (NYSE: A) today announced serial data equalization software for its Infiniium 90000A Series oscilloscope. This software is ideal for testing devices based on high-speed serial data technologies such as PCI Express(r) 3.0, USB 3.0, SATA 6 Gbps, and SAS 6 Gbps. It provides equalization tools for real-time analysis that help engineers significantly reduce receiver errors.

Serial signals consist of a transmitter sending a signal over a medium to a receiver. As data rates increase, the signal quality decreases. This may result in the partial or complete closing of the real-time eye, which will cause the receiver to get corrupt data. Equalization is a technique that allows designers to open real-time eyes at the receiver, which can eliminate bit errors. The Agilent Infiniium serial data equalization software is now a part of the Agilent 90000A Series real-time oscilloscopes and digital signal analyzers. The new software helps engineers quickly model their decision feedback equalization (DFE) and feed-forward equalization (FFE) designs to verify their simulations when it is not possible to probe the transmitter.

This new software reduces complexity and makes testing more convenient. Engineers can select from a list of DFE and FFE options to see how various techniques will affect the eye at the receiver, and they can even compare DFE and FFE in the same window. Users can input tap values (bit-level voltage correction factors) they have created or have the serial data equalization software calculate optimized tap values for them, saving time compared with manual calculations. Agilent’s serial data equalization software provides complete analysis of the equalized eye, including full cursor control for measuring eye height of the equalized eye. The software also offers convolve and de-convolve functions for limited de-embedding capability.

The Infiniium serial data equalization software is fully integrated into the 90000A Series oscilloscope software, allowing it to take advantage of the oscilloscope’s industry-leading noise floor specifications. The 90000A’s low noise floor is critical, as equalization techniques attenuate noise, adding unnecessary errors. The serial data equalization software also benefits from the 90000A Series oscilloscope’s deep memory and flat frequency response, which also are the best in the industry.

“Agilent’s serial data equalization software is one of the most innovative software packages we have launched in recent years,” said Scott Sampl, vice president and general manager of Agilent’s oscilloscope product line. “The software adds features that will save our customers time and boost their confidence in the products they ship in the future. This is the type of product that has made Agilent the fastest-growing major oscilloscope vendor in the market.”

Agilent’s serial data equalization software complements other 90000A Series software such as E2681A EZJIT, N5400A EZJIT Plus and E2688A serial data analysis packages. The software can be ordered as an option when purchasing a new 90000A Series oscilloscope as Option 12. It is also available as a server-based license as N5435A-025.
