Anritsu and Teledyne LeCroy collaborate for PCI Express 4.0 test system

Anritsu and Teledyne LeCroy have announced a partnership to provide the industry’s most capable PCI Express 4.0 (PCIe Gen4) test, integrating the Anritsu Signal Quality Analyzer (SQA) MP1900A BERT with the LabMaster 10Zi-A oscilloscope and QPHY-PCIe4-Tx-Rx software from Teledyne LeCroy.

The resulting system provides high-speed IC, device, says Anritsu while providing network engineers with a single test scenario to conduct automated transmitter and receiver compliance tests, as well as link equalisation verification.

The test system can be expanded to 32Gbit per second, making it the first end-to-end solution to address PCI Express 5.0 (PCIe Gen5) requirements, according to Anristu. The system will also support PCI Express 3.0 (PCIe Gen3) transmitter, receiver and link equalization testing for complete PCI Express ecosystem coverage.

“Anritsu and Teledyne LeCroy share a common goal of providing engineers early availability of accurate and efficient test solutions required to verify their leading-edge designs. Our combined solution . . . fills the market void for a complete physical layer PCIe Gen4 test system that can be easily expanded to PCIe Gen5 as the market continues to develop technologies for high-speed networks,” said Paul Innis, vice president and general manager, Anritsu.

PCIe Gen4 represents a significant test challenge for design engineers, and the companies believe that the combination enables them to accurately measure and validate product performance in accordance with the PCI-SIG standards.

“Recognising that PCIe Gen5 is expected to emerge within two years, we have protected our customers’ investments by creating a clear and efficient upgrade path that will control test costs,” said Conrad Fernandes, vice president of sales, Teledyne LeCroy.

A high-speed BERT that supports 2.4Gbit per second to 32.1Gbit per second, the SQA MP1900A can conduct link training/equalisation and link training and status state machine (LTSSM) analysis. It combines an internal pulse-patter generator (PPG) with integrated 10-tap emphasis and built-in high input sensitivity error detector (ED) with clock recovery, and variable 12dB continuous time linear equalisation (CTLE) and link negotiation functions required for PCI Express receiver tests.

The high-quality waveforms produced allows the MP1900A to conduct reliable jitter and noise tolerance tests, adds the company.

The LabMaster 10-25Zi-A oscilloscope provides the 25GHz bandwidth required for PCIe

Gen4 transmitter testing and receiver test calibration. It may be upgraded in bandwidth to support next-generation serial standards at 32Gbit per second and higher. The LabMaster 10-25Zi-A and the forthcoming QPHY-PCIe4-Tx-Rx software option performs all necessary automation and control for PCIe Gen4 transmitter, receiver, and link equalization test in conjunction with the Anritsu MP1900A. Debugging of PCI Express interfaces is simple and intuitive, says the company, with integrated eye diagram and jitter analysis tools and PCI Express decoding with waveform annotation and tabular analysis.
