</div>BEAVERTON, Ore, Sept. 02, 2026 <a href="https://www.globenewswire.com" target="_blank">(GLOBE NEWSWIRE)</a> -- Tektronix today introduced new automated transmitter and receiver test software for PCI Express® (PCIe®) 7.0 Base designs operating at 128 GT/s. The new TekExpress™ PCIe 7.0 Transmitter Test Application and expanded PCIe 7.0 capabilities in TekRxTest, Tektronix’s receiver test software, help engineers automate transmitter measurements, calibrate precisely stressed receiver signals and validate designs against PCIe 7.0 Base Specification requirements.  Tektronix also expanded its PAMJET Transmitter Analysis Software with advanced PCIe 7.0 capabilities. The software helps engineers identify sources of noise, jitter and other complex signal-integrity problems that standard measurements alone may not explain.   As AI systems scale, moving data efficiently among processors, accelerators, memory, storage and networking becomes as important as adding compute capacity. PCIe provides the high-bandwidth connections among those components, making its continued advancement essential to AI, machine learning, high-performance computing and data center systems.  PCIe 7.0 doubles the PCIe 6.0 data rate to 128 GT/s and supports up to 512 GB/s of bidirectional bandwidth over 16 lanes. Those gains leave far less room for electrical error. At 128 GT/s, channel loss, crosstalk, power delivery noise and jitter become more difficult to isolate, while measurement-system effects can obscure a device’s true performance.   For semiconductor and system developers, these challenges can slow first-silicon bring-up, complicate correlation across engineering teams and allow problems to remain hidden until later development stages. Engineers need repeatable ways to evaluate transmitter behavior, create accurate receiver test conditions and move quickly from a failed measurement to its underlying cause.  “Customers developing PCIe 7.0 designs need confidence that their measurements reflect the device, not the test environment,” said Daryl Ellis, Vice President and General Manager of Tektronix’s Signal Acquisition and Analysis Portfolio. “We combine precise measurement, guided software and direct application expertise to help them solve problems earlier and move PCIe 7.0 designs forward.”  Find problems earlier at 128 GT/s  The new capabilities address three critical stages in PCIe 7.0 electrical validation. By combining TekExpress, TekRxTest and PAMJET with 70 GHz DPO70000SX ATI performance oscilloscope and the Anritsu MP1900A Signal Quality Analyzer-R, engineering teams gain a coordinated PCIe 7.0 Base test solution for transmitter measurement, receiver stress calibration and validation, and root-cause PAM4 analysis.  <ul><li>Automate transmitter testing: The TekExpress PCIe 7.0 Transmitter Test Application automates setup, waveform acquisition, analysis and reporting for transmitter measurements defined in the PCIe 7.0 Base specification, including signal-to-noise-and-distortion ratio, ratio of level mismatch, jitter and transmitter preset equalization. Engineers can evaluate first silicon, compare presets and design revisions, and identify electrical problems before system integration. </li><li>Simplify receiver calibration and validation: TekRxTest controls the Tektronix oscilloscope and the Anritsu MP1900A through one guided workflow for TP3 and TP2 stressed-eye calibration, preset and continuous-time linear equalization (CTLE) optimization, and channel verification. The MP1900A provides the stressed signaling required for PCIe 7.0 receiver calibration and validation. Automated oscilloscope noise compensation supports accurate sinusoidal- and random-jitter calibration, helping engineering organizations create repeatable test conditions across teams and test environments.   </li><li>Move from failure to root cause: Expanded PAMJET capabilities provide noise-aware measurements, clock recovery, correlated and composite eye views, analysis of individual PAM4 transitions and direct navigation to symbol-error events. These capabilities help engineers distinguish device behavior from channel and measurement system effects and expose problems that averaged or aggregate measurements can conceal. </li></ul> Together, these capabilities help engineers validate chip-level designs against PCIe 7.0 Base electrical requirements, laying the groundwork for future CEM implementations and compliance testing. TekExpress and TekRxTest also support workflows for earlier PCIe generations, helping engineering teams retain familiar test processes as they validate backward compatibility and move toward PCIe 7.0.  Confidence as PCIe evolves  As customers adopt each PCIe generation, they must make critical design decisions while requirements, test methods and industry experience are still evolving. For generations of PCIe, Tektronix engineers have actively participated in PCI-SIG Work Groups and pathfinding efforts, applying that knowledge to the software, measurement methods and technical guidance customers use to evaluate designs before deployment.   Tektronix also supports PCI-SIG compliance workshops as a Gold Suite-approved test vendor for PCIe 5.0 and PCIe 6.0, helping engineers evaluate device interoperability and resolve problems early.   Availability  The TekExpress PCIe 7.0 Transmitter Test Application and expanded PCIe 7.0 capabilities in TekRxTest are available now. PAMJET Transmitter Analysis Software is purchased separately and is available now for compatible Tektronix high-performance oscilloscopes.   Learn more about Tektronix PCIe test solutions at <a href="https://www.globenewswire.com/Tracker?data=4UBqrWMoRCLDm4UKERkVHD_Q2YSCp8vHEaFcVyIvUjbVDoeA7yIfFjNn04oNflwYUC6M6hvb539_0Oh5R7xGnWYdmMDcv63YK6hpsOoYYWqx_6ObCMv3HeXrYby5xt3EkXbXPxxtAFLvWJGaNo1LoGDrlWh4m2ly-Cwy8dqIv_8=" rel="nofollow" target="_blank" title="tek.com/pci-express">tek.com/pci-express</a>. # # #  About Tektronix  Tektronix is the partner engineers have trusted to measure, discover, and innovate for 80 years.
