A PCI Express 5.0 (PCIe Gen5) test solution combines Anritsu’s Signal Quality Analyzer-R MP1900A BERT series with Tektronix’s DPO70000SX series 70-GHz Real-time Oscilloscope and automation software. The all-in-one solution supports tests of PCIe 5.0 electrical characteristics, physical-layer protocol analysis, and transmitter/receiver and Link Equalization Training (LEQ) tests to facilitate efficient development of high-speed ICs, devices, and networks used in emerging environments, including 5G.
The Anritsu and Tektronix end-to-end solution can be quickly configured to support required PCIe 
5.0 specifications and supports automated transmitter test, receiver jitter tolerance test, and Tx/Rx LEQ compliance test items. It incorporates waveform-calibration automation software with analysis functionality using event trigger and high-speed calibration between the MP1900A BERT and DPO70000SX oscilloscope to reduce test times. Cost-of-test is lowered, as the solution supports PCIe 1.0-5.0 without a hardware upgrade and can upgrade to PCIe 6.0 test capability with a minimum hardware investment.
The Signal Quality Analyzer-R MP1900A series is a multi-channel BERT for designing and testing next-generation network interfaces, such as 200G/400G/800G Ethernet, as well as high-speed bus interfaces, including PCI Express 4.0/5.0, USB3.2, USB4, and Thunderbolt. It has a built-in pulse pattern generator (PPG) that produces best-in-class high-quality waveforms (115 fs low intrinsic jitter), as well as a high-sensitivity (15 mV) error detector (ED). A jitter (SJ, RJ, SSC, BUJ) generation source and CM-I/DM-I/white-noise generation source are also integrated into the instrument. Link Training and Link Training Status State Machine (LTSSM) analysis functions support various applications, including compliance tests, margin tests, and troubleshooting.
With functions for evaluating PAM4 of optical modules, SERDES, and other technologies used by data-center 200G/400G/800G Ethernet systems, the MP1900A BERT also evaluates PCIe 6.0 (PAM4 32 Gbaud) devices under development to ensure compliance with the latest PCI-SIG standard. This expanded analysis capability controls test infrastructure costs.
The Tektronix DPO70000SX series 70-GHz Real-time Oscilloscope is linked with the Anritsu Signal Quality Analyzer-R MP1900A BERT as an automated PCIe Gen5 (32 GT/sec) Base & CEM transceiver solution. The new Tektronix receiver test automation software uses an optimization algorithm to correct 32 GT/sec and 16 GT/sec stressed-eye waveforms to shorten test times using the leading SigTest Phoenix test tool and fast parallel processing. Moreover, support for multiple form factors (M.2 and U.2) and clocking architectures (CC, SRNS, SRIS) supports A/D range optimization and low-noise PCIe Gen5 Base specification 32 GT/s uncorrelated jitter and pulse-width jitter measurements.
