Tektronix develops new Signal Path
Low-noise Oscilloscope Architecture for High-Speed Signals
The oscilloscopes of the new 7-series DPO from Tektronix are designed for maximum signal integrity. A newly developed signal path architecture with proprietary ASIC, 10-bit ADC, and “QuietChannel” technology is supposed to enable users to display signals more precisely than ever before.
Tektronix launches the 7 Series DPO, its most powerful oscilloscope and first in its class of ultra-high-performance instrumentation.
Featuring Tek’s latest signal path and data processing advancement—including two newly developed, custom ASICs—the 7 Series is purpose-built for engineering teams and researchers pushing the boundaries of high-speed communications, high-energy physics, AI, and quantum computing.
With bandwidth scalable from 8 GHz to 25 GHz and up to 5x faster data offload than legacy systems*, the 7 Series helps teams capture and analyze complex signals with dramatically less noise—helping them see more, know more, and move faster.
“When the limits of your test system become the limits of your innovation, it’s time for a new approach,” said Maria Heriz, Chief Product Officer at Tektronix. “The 7 Series DPO was designed in collaboration with engineers working on the world’s most complex challenges, so it reflects what they need most, including high-frequency coverage, low noise, and fast analysis. This scope gives our customers the capabilities and confidence they need to achieve breakthroughs.”
Precision at the performance edge
Early customer collaborators include researchers in high-energy physics, leading semiconductor manufacturers, national labs, and RF system integrators—all of whom helped shape the series’ priority features:
- Industry-leading effective number of bits (ENOB)—7,5 Bit at 8 GHz up to 6,5 Bit at 25 GHz
- New QuietChannel signal path architecture to reduce internal noise and amplify weak signals without compromising bandwidth or visibility
- High-speed interface technology + 10Gb data offload for up to 5x faster waveform transfer compared to legacy oscilloscopes*—essential for high-throughput validation labs
- Bandwidth upgradeability from 8 GHz to 25 GHz to support evolving test needs
- Compatibility with the TekConnect probe interface to preserve a seamless transition into existing test infrastructure
- Native integration between serial signal analysis tools and the user interface for a powerfully reimagined workflow
- Windows and Linux support
Powered by proprietary, custom silicon
The 7 Series DPO is built on a next-generation signal path architecture, combining custom ASICs, optimized FPGAs, and a high-performance GPU to reduce noise, preserve signal integrity, and accelerate analysis. Tektronix’s latest chipsets—TEK079 and TEK085—reflect years of focused engineering to advance measurement precision in high-performance test environments. More than a feature, this architecture forms the foundation of Tektronix oscilloscopes and represents significant progress in high-performance testing. Every specification is rigorously validated in partnership with metrology experts, ensuring trusted accuracy where it matters most.
