Superior, Automated PCIe Tx, Rx and LEQ Compliance Testing

Teledyne LeCroy's LabMaster 10 Zi-A oscilloscopes and Anritsu’s Signal Quality Analyzer-R (SQA-R) MP1900A are certified for all PCIe compliance tests. Superior electrical performance and tighter integration mean the best repeatability, with faster test times.


Approved Solution for all PCI-SIG Electrical Compliance Tests

LabMaster 10Zi-A and the SQA-R MP1900A meet all requirements for Gen1, Gen2, Gen3, Gen4, Gen5, and Gen6 PCI-SIG electrical tests:

  • PCIe 3.0 Receiver test
  • PCIe 3.0 Transmitter tests
  • PCIe 3.0 Link Equalization tests
  • PCIe 4.0 Receiver test
  • PCIe 4.0 Transmitter tests
  • PCIe 4.0 Link Equalization tests
  • PCIe 5.0 Receiver tests
  • PCIe 5.0 Transmitter tests
  • PCIe 5.0 Link Equalization tests
  • PCIe 5.0 Reference Clock Jitter Test
  • PCIe 6.0 Transmitter tests
  • PCIe 6.0 Receiver Calibration
  • PLL Bandwidth test

Highest Accuracy and Repeatability

Teledyne LeCroy QualiPHY software for PCIe fully automates the oscilloscope and MP1900A for calibration and testing. This simplifies complex processes and eliminates confusion and setup errors.

With time and temperature jitter drift of less than +/- 2% (2 days, +/- 5 deg), the MP1900A has the highest signal quality for the most repeatable results.

Fastest Receiver Test Calibration

iA typical PCIe receiver test calibration requires hundreds of SigTest analyses. Competitive scopes only have 4- or 8-core processors with 16 or 32 GB of RAM. The LabMaster 10 Zi-A uses an Intel® Xeon® Gold 6240R 24-core server-class CPU with up to 192 GB of RAM.

Visibility from Electrical Through Transaction Layer

Automated characterization and compliance testing are vital to bringing a product to market, but when failures occur, it falls to the rest of the instruments’ toolbox to help locate and debug problems. Teledyne LeCroy and Anritsu provide visibility into the most layers of the PCI Express interface, to get to the root-cause of issues faster.


LTSSM Logging and State-machine Triggering

After a training operation, the MP1900A displays the actual Training State transition logs, so the state transition path (route) and transition times can be analyzed in detail.

State transitions can be selected as the oscilloscope acquisition trigger, allowing the link training operation to be analyzed in depth using ProtoSync on the oscilloscope.

Integrated Protocol and Physical-layer Analysis

PCIEBus Decode and ProtoSync protocol analysis software provide views of the complete protocol stack, from physical layer to transaction layer. Physical layer and protocol views are linked directly to each other at all times touch a packet on either software interface, and the oscilloscope will highlight and zoom to that packet in both views.

Debug During LEQ Testing

QualiPHY PCIe software leverages Teledyne LeCroy’s ProtoSync, allowing you to switch seamlessly from electrical to protocol views during the LEQ tests—a feature unique to our solutions. If a failure or issue is detected, the oscilloscope, BERT and Device Under Test are already configured to provide unmatched visibility into the entire link training operation.

Experience, Leadership, Support

Combining the Teledyne LeCroy LabMaster 10 Zi-A oscilloscope and QualiPHY automated compliance test software with the Anritsu SQA-R MP1900A BERT results in the most powerful characterization, compliance and debug solution available. First-line support for the solution is available directly from the industry’s most experienced PCI Express field support team at Teledyne LeCroy.
