To ensure interoperability, PCIe 5.0 devices need to pass receiver compliance tests for certification by the PCI-Special Interest Group (PCI-SIG®). PCIe 5.0 technology encompasses both the base specification for silicon-level development and the card electromechanical (CEM) specification for motherboards and add-in cards. The physical layer (PHY) test specification provides guidance for testing using the CEM form factor.
Before conducting a receiver test, a bit error ratio tester (BERT) pattern generator must be calibrated with an oscilloscope to transmit a worst-case stress test signal. This process involves adding impairments, including incremental loss-induced intersymbol interference (ISI). After calibration, the receiver of the device under test (DUT) applies the test signal, measuring parameters such as the bit error ratio.
