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. QPHY2-PCIE1-PCIE2-TX provides a step-by-step guide to correctly perform the test. Then configures the instrument, performs the test, and records the results.

During transmitter link equalization, the transmitter's emphasis not only needs to respond to the correct equalization request, but it also needs to change within a specified time. The waveform contains information about 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.

PCI Express testing requires multiple power cycles, reset operations, and transmitter preset toggles 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 automation controller is a low-cost accessory connecting directly to the oscilloscope for total PCIe 3.0 test automation - further reducing test times and eliminating chances for operator error.
