Anritsu Corporation is pleased to announce that iPasslabs Technology Co., Ltd. has successfully been certified as a PCI-SIG Authorized Test Lab by utilizing the Anritsu Signal Quality Analyzer-R MP1900A. This enables iPasslabs to provide PCI Express® (PCIe) receiver sensitivity and other compliance certification services to customers worldwide. As an industry-leading test lab, iPasslabs is dedicated to high-speed communication interface testing, as well as signal integrity simulation and analysis. In collaboration with Credo, iPasslabs has also completed the industry’s first PCIe 6.0 Retimer performance validation. Credo’s PCIe 6.0 Retimer leverages low-latency, low-power digital signal processors (DSPs) and SerDes technologies to significantly extend PCIe transmission distances within AI and server systems, addressing the growing demands of high-performance data centers and modern network infrastructure.

Anritsu’s MP1900A automated verification system includes pre-system calibration and jitter tolerance testing. Its ability to perform automatic, iterative calibration and verification ensures stable and fast test results, offering crucial support for optimizing data center network architectures, AI computing accelerators, and large Ethernet switch designs. At the core of this system lies the Signal Quality Analyzer-R MP1900A — a high-performance, multi-channel bit error rate tester (BERT) that delivers comprehensive measurement capabilities. It fully supports the R&D and design requirements of next-generation network interfaces such as 800G/1.6T Ethernet, as well as high-speed bus interfaces including PCI Express 6.0/7.0, USB4 v2, and Thunderbolt™. The MP1900A features a built-in Pulse Pattern Generator (PPG) that delivers industry-leading waveform quality, with ultra-low intrinsic jitter (115 fs rms), and a high-sensitivity Error Detector (ED) capable of detecting signals as low as 15 mV. It also integrates multiple jitter generation sources (SJ, RJ, SSC, BUJ), common-mode and differential-mode interference sources (CM-I/DM-I), and white noise generation. Furthermore, with support for link training and Link Training and Status State Machine (LTSSM) analysis, it comprehensively supports various applications including compliance testing, margin testing, and troubleshooting.

“The Anritsu MP1900A is a critical tool that enables iPasslabs to support our customers in high-speed receiver signal measurements, debugging, and characterization,” said Eric Shen, CEO of iPasslabs Technology. He noted that the collaboration with Anritsu began at the company’s founding. With the support of Anritsu’s Bit Error Rate Testers (BERTs) and Vector Network Analyzers (VNAs), iPasslabs has been able to quickly meet customers’ needs for testing, debugging, and signal integrity analysis. Eric Shen further emphasized that iPasslabs is now fully equipped to perform complete receiver jitter tolerance testing for PCIe 6.0 and 400G/800G high-speed Ethernet applications. Looking ahead, iPasslabs anticipates continued collaboration with Anritsu on next-generation testing needs, including PCIe 7.0 and ultra-high-speed Ethernet at 1.6 Tbps and 3.2 Tbps.

At Credo, helping to enable the test ecosystem is an important step in accelerating the adoption of PCIe 6.0 products,” said Phil Kumin, AVP of Product at Credo. “We were excited to work with iPasslabs and Anritsu in enabling PCIe 6.0 retimer performance verification.”

“With the rapid growth of AI servers and related markets, the demand for high-speed interface testing has surged. However, few certified labs currently possess the comprehensive testing capabilities required to meet these evolving needs,” said Ivan Chen, General Manager of Anritsu Taiwan. “Anritsu is honored to support iPasslabs in establishing a PCI-SIG certified test lab with our high-performance Signal Quality Analyzer-R MP1900A and expert technical support, and to have collaborated on the successful validation of Credo’s PCIe 6.0 Retimer chip—helping lay a solid foundation for the global high-speed market.”
