Tektronix has launched the DPO718AX, an eight-channel digital phosphor oscilloscope designed for high-speed serial validation. This 25 GHz bandwidth instrument is now available for engineers working on multi-lane interface development.
Why it matters
The system enables simultaneous synchronized signal capture across eight lanes, accelerating validation for advanced high-speed serial interfaces. This capability is critical for hardware engineers addressing the increasing complexity of modern data interconnect standards.
The DPO718AX provides eight synchronized channels at 25 GHz bandwidth or four-channel operation at 125 GS/s. It includes 96 GB of memory and over 1.6 TB of NVMe storage, powered by an AMD EPYC Embedded 3351 processor and an Nvidia T1000 GPU.
The players
Tektronix
A provider of test, measurement, and monitoring equipment specializing in oscilloscopes and signal analysis solutions for the semiconductor and communications industries.
AMD
A semiconductor company that produces high-performance computing processors, including the EPYC Embedded series used for data-intensive processing.
Nvidia
A technology firm known for GPU architecture that powers graphics rendering and parallel compute tasks in professional-grade instrumentation.
The details
The instrument employs Tek85 low-noise preamplifiers—specialized signal boosters—and Tek79 12-bit ADCs (analog-to-digital converters that transform voltage signals into digital data) to maintain signal integrity at high frequencies. It utilizes QuietChannel technology, a continuous-time linear equalization method that reduces noise during signal processing. The device is housed in an 8U rack-mount form factor and incorporates a 15.6-inch 1080p touchscreen for waveform analysis.
Timeline
September 2025: The 7 Series DPO platform debuted.
September 24, 2026: Official launch of the DPO718AX.
Fall 2026: Scheduled introduction of the P7725 TriMode probe.
The Tech Race
The DPO718AX advances the field of high-speed serial validation by integrating multi-lane capture specifically for the latest interface protocols. It follows a trajectory set by USB4v2 compliance requirements, positioning Tektronix against existing solutions that often require separate instruments for high-channel-count synchronized testing.
Hardware developers and validation engineers can immediately utilize the device to streamline automated compliance workflows. Those requiring specialized probing for specific high-speed interconnects will need to wait for the P7725 accessory rollout in the fall of 2026.
The takeaway
The move to eight-channel, 25 GHz acquisition reflects the industry shift toward higher-density serial validation. Interested labs should monitor the fall 2026 probe launch for the full expansion of the DPO718AX toolchain.
What happens next
The company is scheduled to introduce the P7725 TriMode probe in the fall of 2026.
