QPHY2-PCIE4-TX-RX PCI Express 4.0 electrical transmitter and receiver software is a fully automated test solution meeting the PCIe 4.0 Base specification and PCIe 4.0 PHY Test Specification requirements for characterizing and compliance testing both transmitters and receivers.

In-depth debug and characterization analysis by emulating the transmitter’s reference PLL and CTLE behaviors to ensure the electrical signal timing and jitter meet the compliance specification.

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. QPHY2-PCIE4-TX-RX controls both the oscilloscope and BERT to automate the entire iterative calibration process.

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

During transmitter link equalization, the transmitter's emphasis not only needs to respond to the correct equalization request, it needs to change within a specified time. The voltage waveform has information on when the change occurs at the physical layer, but not when the change request was made in protocol. ProtoSync leverages Teledyne LeCroy's industry-standard protocol analysis software to decode the acquired waveform up to the transaction layer. This enables QualiPHY 2 to determine the precise timing of the equalization change request, for full visibility into link training behavior.

• Sets up and controls the Teledyne LeCroy WavePulser 40iX during measurements
• Guides the user with a connection diagram at each step of the process
• Automatically makes the measurements and transfers measured data to QualiPHY 2 compliance test software
• Performs all the necessary additional calculations within the QualiPHY 2 compliance test software
• Generates a complete report for the PCIe fixture characterization, equivalent to the existing manual process
