Tektronix Inc. has announced its support for Intel and the PCI Express (PCIe) ecosystem in the testing and verification of the Intel Xeon Processor E5-2600 family. Formerly known as Romley, the platform targets high-performance server and data center applications, stated the company.

According to the company, the Intel Xeon Processor E5-2600 family is the industry's first server processor with integrated PCIe 3.0, reducing I/O latency by as much as 30 percent and nearly doubling I/O bandwidth. Among the Tektronix products used to support the development of the integrated I/O capability are the DPO/DSA/MSO70000 Series oscilloscopes, TLA7SA16 and TLA7SA08 logic protocol analyzer modules and TLA7000 series logic analyzers, and BERTScope bit error rate testers.

The Intel development team selected Tektronix as the protocol test vendor for early silicon verification of Intel Xeon Processor E5-2600 family I/O performance. This led to significant, in-depth support for verification that is now publicly available for OEM/ODM use. With fast data rates and improved I/O bandwidth over previous generations, the PCIe 3.0 specification brings new complexity and testing challenges in both the physical and the protocol layers, now fully met by Tektronix solutions, boasted the company.

At 100GSPS, DPO/DSA/MSO70000 Series oscilloscopes deliver the performance and signal fidelity required to meet PCIe 3.0 test challenges, Tektronix indicated. Option PCE3 for these instruments accelerates the analysis and validation of PCIe designs and provides the flexibility to check devices for pre-compliance or perform device characterization or debug in a single software package.

Serial Data Link Analysis software enables channel de-convolution, convolution and receiver equalization. DPOJET jitter and eye-diagram analysis software provides jitter, eye-diagram and parametric testing. The P7520 TriMode Differential Probe is available for validation and debug of chip-to-chip links, including common mode measurements, added the firm.

These tools also integrate with the TLA7SA16 and TLA7SA08 logic protocol analyzer modules and the TLA7000 Series logic analyzers to provide complete visibility of PCIe 3.0 physical and logical layers.

Tektronix provides a method of implementation (MOI) for PCI Express 3.0 receiver testing using the BERTScope BSA85C. The full set of receiver test challenges is addressed in the MOI including putting devices into loopback, setting and calibrating the required stresses and pre-emphasis, and performing jitter tolerance tests.

Tektronix PCIe 3.0 test solutions are available worldwide.
