Why Measurement Fidelity Matters in HPC
Modern HPC designs rely on technologies such as PCIe Gen6, DDR memory, high-speed Ethernet, PAM4 signaling, and high-density AI accelerators. Even small amounts of noise, jitter, or signal distortion can lead to interoperability issues or unexpected failures. Tektronix identifies High-Speed I/O, Networking, Communication Interfaces, and Power Delivery Networks as critical areas requiring accurate validation throughout the development cycle.
The DPO70000SX provides up to 70 GHz bandwidth and up to 200 GS/s real-time sampling performance, enabling engineers to capture and analyze signals with exceptional accuracy.
ATI Architecture: Built for High-Speed Signal Integrity Analysis
One of the key differentiators of the DPO70000SX is Tektronix’s patented Asynchronous Time Interleaving (ATI) architecture. Unlike conventional oscilloscope architectures that divide signal energy across separate frequency paths, ATI preserves signal integrity through a unique acquisition approach designed to reduce noise and improve measurement fidelity.
For HPC engineers, this translates into:
- Lower measurement noise
- Better signal-to-noise ratio (SNR)
- More accurate jitter measurements
- Greater confidence when validating PAM4 and high-speed serial links
These advantages become increasingly important as data rates continue to rise across AI servers and next-generation networking environments.
