The PCI-SIG defines a standard set of CEM compliance tests that a device needs to pass for certification, and each test has unique requirements from the test equipment. QPHY-PCIE3-TX-RX first provides a step-by-step guide of how a customer's device and the test solution needs to be connected together to correctly perform the test. It then enables and configures the appropriate set of instrument features, performs the test, and records the results.

Often, compliance testing is a very difficult task. The user must make the necessary connections between the oscilloscope and the device under test, manually configure the oscilloscope for the appropriate measurement, perform the test procedure as specified by the test specification, record the results and finally compare the results to the appropriate limit in the compliance specification. QPHY-PCIE3-TX-RX performs many of these steps automatically, decreasing test time and improving repeatability and confidence.

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 to determine the precise timing of the equalization change request, for full visibility into link training behavior.

Testing for PCI Express requires multiple power cycles, reset operations, and transmitter preset toggles to be applied to the device under test. In previous iterations of the standard this was either a cumbersome manual process, or required expensive additional signal generators to automate. The Teledyne LeCroy TF-PCIE4-CTRL CBB automation controller is a low-cost accessory that connects directly to the oscilloscope an is fully integrated into QPHY-PCIE3-TX-RX to enable total test automation for PCIe 3.0 testing - further reducing test times and eliminating chances for operator error in complex test environments.

The next generation of PCI Express 6.0 operates at 64 Gb/s data rate. PCIe 6.0 compliance testing requires a higher bandwidth oscilloscope, and a BERT system which is protocol-aware at 64 Gb/s. The LabMaster 10Zi-A family of oscilloscopes and the MP1900A SQA-R already fulfill all these hardware requirements. The Teledyne LeCroy/Anritsu PCI Express test solution represents not only a system for the current generation of PCI Express, but an investment in the development and testing of future technologies.

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