Summary points:

  • Emerson introduces NI USRP X420 SDR platform designed for advanced radar, satellite communications, and emerging 6G research applications.
  • Frequency coverage up to 20 GHz enables access to higher-frequency spectrum including FR3, Ku-, and X-bands for multi-channel radar, non-terrestrial networks, and integrated sensing and communications (ISAC).
  • Phase-coherent multi-channel architecture and high instantaneous bandwidth help engineers rapidly develop and validate complex RF systems for aerospace, defense, wireless, and academic research.

AUSTIN, Texas – The Emerson Electric co. Process Management segment in Austin, Texas, is introducing the NI USRP X420 software-defined radio (SDR) for advanced radar systems, satellite communications, and emerging 6G research.

The X420 expands the NI Universal Software Radio Peripheral (USRP) with frequency coverage to 20 gigahertz to open access to higher-frequency spectrum including FR3, Ku, and X bands for multi-channel radar, non-terrestrial networks (NTN), integrated sensing, and communications (ISAC).

The X420 enables researchers and engineers to develop and validate complex RF systems rapidly across aerospace, defense, wireless communications and academic research environments.

Features include frequency range to 20 GHz; phase-coherent multi-channel architecture; high instantaneous bandwidth; accessible high-end RF capability; and top-of-the-line USRP: Offers most advanced RF performance from Emerson's USRP product portfolio to date.
