The new N5461A Infiniium serial data equalisation software, from Agilent Technologies , enables oscilloscope users to test high-speed serial designs.

Agilent Technologies have announced the serial data equalisation software for their Infiniium 90000A series oscilloscopes.

The N5461A Infiniium serial data equalisation software is suitable 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 equalisation tools for real-time analysis that help engineers to 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 causes the receiver to get corrupt data.

Equalisation is a technique that allows designers to open real-time eyes at the receiver, which can eliminate bit errors. The N5461A Infiniium serial data equalisation software is now a part of the Agilent Technologies 90000A series real-time oscilloscopes and digital signal analysers.

The N5461A Infiniium serial data equalisation software helps engineers to quickly model their decision feedback equalisation (DFE) and feed-forward equalisation (FFE) designs to verify their simulations when it is not possible to probe the transmitter.

The N5461A Infiniium serial data equalisation software reduces complexity and makes testing 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 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 equalisation software calculate optimised tap values for them, saving time compared with manual calculations.

Agilent Technologies N5461A Infiniium serial data equalisation software provides a complete analysis of the equalised eye, including full cursor control for measuring eye height of the equalised eye.

The N5461A Infiniium serial data equalisation software also offers convolve and de-convolve functions for limited de-embedding capability.

The N5461A Infiniium serial data equalisation software is integrated into the 90000A series oscilloscope software, allowing it to take advantage of the oscilloscope's noise floor specifications. The 90000A series low noise floor is critical, as equalisation techniques attenuate noise, adding unnecessary errors.

The N5461A Infiniium serial data equalisation software also benefits from the 90000A series oscilloscopes deep memory and flat frequency response.

Agilent Technologies N5461A Infiniium serial data equalisation software is an addition to 90000A series software, such as E2681A EZJIT, N5400A EZJIT Plus and E2688A serial data analysis packages.

The Infiniium serial data equalisation 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.
