R&S announces new frequency models up to 54 GHz for vector network analyser
Designed to combine precision and speed in a scalable platform, the R&S ZNB3000 vector network analyser from Rohde & Schwarz helps engineers and researchers accelerate innovation in high-performance RF applications and signal integrity testing. By extending the maximum frequencies up to 32 GHz, 43.5 GHz and 54 GHz, Rohde & Schwarz addresses even more applications with the R&S ZNB3000, from RF component testing for 5G, 6G and Wi-Fi applications to advanced high-speed interconnect testing for AI data centres and next-generation RF component testing for satellite communications in the Ka band and V band.
AI applications in data centres demand ultra-fast, high-bandwidth interconnects to efficiently handle massive data loads. Technologies such as high-speed Ethernet (IEEE 802.3ck) require testing solutions that can operate at frequencies up to 50 GHz to ensure optimal signal integrity. The new PCIe 7.0, Peripheral Component Interconnect Express, currently under development, will double the supported data rates up to 128.0 GT/s. This requires testing at higher frequencies, as well.
Covering up to 54 GHz, the R&S ZNB3000 is designed to meet these requirements, enabling precise characterisation of high-speed PCBs, cables, and interconnects used in AI data centre infrastructure. At EuMW 2025, Rohde & Schwarz demonstrates the new 54 GHz model of the R&S ZNB3000 for the first time in public. The setup, which includes a PCIe cable as the device under test (DUT), showcases how to ensure the reliability of high-speed interconnects for AI-driven workloads.
The new high-frequency models also support advanced RF component testing for SatCom applications in the Ka and V bands, such as filters, mixers, amplifiers, switches and beamformers, which operate at these high frequencies. It also enables RF component testing for 5G, 6G and Wi-Fi applications.
