TLC PCIe Test04 February 2019 – Teledyne LeCroy announced support for PCI Express 5.0 physical layer testing with an advantage in calibration and test completion time, expanding on what is already an extensive set of PCI Express test solutions.

Demand for higher throughput in storage devices and data centers requires data-transfer rates higher than PCIe 4.0’s 16 GT/s. Therefore, PCIe 5.0, at 32 GT/s, is expected to see rapid adoption. Teledyne LeCroy, an industry leader for PCI Express test equipment, now extends its physical-layer test domain to enable that adoption. The new Teledyne LeCroy QPHY-PCIE5-TX-RX physical-layer software option for LabMaster 10Zi-A series oscilloscopes provides:

  • Automated receiver-test calibration for jitter-tolerance testing at the full 32 GT/s PCIe 5.0 rate. While existing solutions can take up to a full day to calibrate before even starting the test, the Teledyne LeCroy calibration will be completed in a fraction of that time.
  • Automated collection of waveforms and testing of PCIe 5.0 transmitter parameters to significantly speed and simplify test throughput.
  • Support for characterization of PCIe signals in both common-clocked and independently-clocked (SRIS/SRNS) architectures, linking Teledyne LeCroy’s SDAIII-CompleteLinQ jitter-decomposition, eye-diagram, and noise-analysis software with new capabilities for faster PCIe 5.0 debug.

See a demonstration of the QPHY-PCIE5-TX-RX software with a LabMaster 10-65Zi-A, 65 GHz oscilloscope and an Anritsu Signal Quality Analyzer (SQA) MP1900A BERT at DesignCon 2019 in Santa Clara, CA in Teledyne LeCroy booth #519.
