Automated Test Solution for PCI Express 5.0

15 September 2022 – Granite River Labs (GRL), a company providing digital connectivity test solutions and services, and Anritsu Corporation announced that their jointly-developed PCI Express (PCIe) 5.0 automated test solution has been approved by PCI-SIG for “gold suite” product compliance testing. The solution combines Anritsu’s Signal Quality Analyzer-R MP1900A BERT series with GRL’s PCI Express 5.0 CEM Specification Receiver and PLL Peaking and Bandwidth test automation software.

The Anritsu and GRL solution offer product developers a fast and flexible way to test PCIe 5.0 Host and Add-In Card designs with any Tektronix or Keysight real-rime oscilloscope. The solution compliments GRL’s PCIe 5.0 CEM Transmitter test automation software, also approved by the PCI-SIG for “gold suite” compliance testing, and PCIe 5.0 Base Specification Receiver software, both compatible with Tektronix and Keysight scopes.

Reducing equipment calibration and test time

The GRL software’s simple user interface automates complex PCIe specification testing and significantly reduces the time requires for equipment calibration and testing. In accordance with the PCIe 5.0 CEM specification, the software features automated calibration of signal impairments to achieve stressed Receiver Eye Height and Eye Width, and performs PCIe TX and RX Link Equalization (Link EQ) and PLL Peaking and Bandwidth tests at 8, 16, and 32GT/s. All PCIe CEM compliance tests are automated in a single software framework.

Controlling the cost of test infrastructure

The Anritsu 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 and high-speed bus interfaces like PCI Express 4.0/5.0 specifications, USB3.2, USB4, and Thunderbolt.

Built in PPGs (pulse pattern generators) and error detectors (EDs) allow the MP1900A BERT to generate high-quality waveforms with low intrinsic jitter (115 fs). The instrument also features an integrated jitter generation source (SJ, RJ, SSC, BUJ) and a CM-I/DM-I/white-noise generation source. Along with compliance tests, margin tests, and troubleshooting, the unit also supports variety of other applications, including Link Training and Link Training Status State Machine (LTSSM) analysis functions.

In addition to testing PAM4 optical modules, SERDES, and other technologies used by data center 200G/400G/800G Ethernet systems, the MP1900A BERT also tests PCIe 6.0 (PAM4 32 Gbaud) devices under development to ensure compliance with the latest PCI-SIG standard. This allows enterprises to keep the cost of test infrastructure under control.

About PCI-SIG

PCI-SIG is the consortium that owns and manages PCI specifications as open industry standards. The organization defines industry standard I/O (input/output) specifications consistent with the needs of its members. Currently, PCI-SIG is comprised of over 900 industry-leading member companies.
