Keysight and AttoTude Collaborate on Advanced Signal Analysis Solutions for THz Interconnect Development

Enhancements to Keysight’s 89600 VSA software enable AttoTude to accelerate characterization of THz radio technology for AI data centers

SANTA ROSA, Calif.--(BUSINESS WIRE)--Keysight Technologies, Inc. (NYSE: KEYS) today announced that AttoTude Inc., a provider of terahertz (THz) interconnect technology for AI and hyperscale data center applications, has adopted enhanced signal analysis capabilities in Keysight’s 89600 Vector Signal Analysis (VSA) software to accelerate development of its THz radio technology.

AttoTude is transforming data center interconnects with an ASIC-based transmission over low-loss THz waveguides solution, addressing the bandwidth, reliability, and energy efficiency challenges facing AI infrastructure. The company’s THz platform operates at frequencies up to 1 THz, with data rates reaching 225 Gbaud using advanced modulation formats including PAM4 and multi-level QAM.

Keysight’s UXR Oscilloscope and 89600 VSA software, with the VSA’s FlexFrame measurement capability, provide AttoTude with critical signal analysis tools for characterizing high-speed waveforms modulated onto THz carriers. Recent enhancements to FlexFrame include improved frequency estimation algorithms that work reliably in challenging channel conditions, streamlined predistortion and Rx equalization capabilities, and expanded modulation format support.

Dave Welch, Co-founder and CEO of AttoTude, said: “As we push the boundaries of THz communications for AI data centers, it is essential to have advanced signal analysis tools that can keep pace with our innovations. Keysight’s UXR Oscilloscope and 89600 VSA software with FlexFrame capabilities have proven invaluable in validating and evolving our THz technology. Keysight’s supportive partnership with our team significantly improved the speed and confidence of our learning cycles.”

Joachim Peerlings, Vice President and General Manager of Keysight’s Networks and Data Center Group, said: “To keep pace with the growing compute demand that is needed for AI, the industry welcomes new companies with innovative concepts that add to the breadth of solutions that Keysight enables. AttoTude represents the kind of innovative customer that drives us to continually advance our signal analysis capabilities. We are proud to enable their pioneering work in THz interconnect technology for AI applications.”
