Anritsu Corporation President Hirokazu Hamada and Tektronix have announced that they will provide an automated PCI Express 5.0 (PCIe Gen5) test solution combining Anritsu’s Signal Quality Analyser-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 Equalisation Training (LEQ) tests to facilitate efficient development of high-speed ICs, devices, and networks used in emerging environments, including 5G.

Anritsu and Tektronix’s 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 function 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 Analyser-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.
