PCI Express 5.0 introduces a new set of physical-layer testing demands at a transfer rate of 32 Gb/s. QPHY-PCIE5-TX-RX addresses these challenges with a fully-integrated compliance test solution for both Transmitter (Tx) and Receiver (Rx) testing to the PCI Express 5.0 Base specification and CEM specification, including receiver test calibration with the Anritsu MP1900A SQA-R.

Full test integration with QualiPHY

Teledyne LeCroy's QPHY-PCIE5-Tx-Rx software performs all necessary automation and control of the LabMaster 10 Zi-A and SQA MP1900A for PCIe 5.0 transmitter and receiver tests. QPHY-PCIE5-Tx-Rx guides the user through making the necessary connections between the instruments and the device under test. It then automatically configures the system to make the appropriate measurements, performs the test procedure as defined in the test specification, and finally compares the results to the appropriate limits in the compliance specification. The process produces full reports in HTML or PDF format, and may be externally automated for high-throughput validation and production testing.

Receiver Test Calibration

To test a PCI Express receiver, the signal applied must meet stipulated voltage swing and preset levels, precisely calibrated noise and jitter impairments, and a prescribed level of eye closure due to channel loss. QPHY-PCIE5-TX-RX controls both the oscilloscope and the BERT to automate the entire iterative calibration process, including:

  • Voltage swing and preset emphasis levels
  • Random and sinusoidal jitter addition
  • Differential-mode and common-mode noise
  • Eye closure through loss channel selection

Fast test execution

PCI Express transmitter compliance testing and receiver test calibration require the acquisition of the specified signals with the optimal dynamic range, correct number of Unit Intervals, and appropriate emulated package loss models. QPHY-PCIE5-Tx-Rx automatically configures each acquisition cycle correctly, saves the appropriate waveform files, and processes them with the SigTest tool as required for PCI Express testing. Leveraging the LabMaster 10Zi-A's up to 20 processor cores enables many instances of SigTest to run concurrently, leading to dramatically reduced test times.

Transmitter characterization

Teledyne LeCroy's SDAIII CompleteLinQ option is ideal for deeper characterization of PCI Express signals, including:

  • Eye diagrams
  • Jitter and noise analysis
  • Fixture de-embedding and channel emulation
  • Transmitter emphasis emulation
  • DFE and PCI Express reference CTLE receiver equalizer emulation
  • PCI Express reference PLL for clock recovery of both common-clocked and SRIS/SRNS devices


QualiPHY is designed to reduce the time, effort and specialized knowledge needed to perform compliance testing on high-speed serial buses.

  • Guides the user through each test setup
  • Performs each measurement in accordance with the relevant test procedure
  • Compares each measured value with the applicable specification limits
  • Fully documents all results
  • QualiPHY helps the user perform testing the right way-every time!
