Testing Signals At Higher Frequencies

AI, data, and satellites need signals to run faster than ever. But how can engineers test them right? See the tool built for tomorrow’s systems.

Engineers developing AI data centers, high-speed networks, and wireless systems face a growing challenge: testing signal integrity and RF performance at higher and higher frequencies. Standards like high-speed Ethernet (IEEE 802.3ck) already require validation up to 50 GHz, while the upcoming PCIe 7.0 standard doubles data rates to 128 GT/s, demanding even more precise measurement. Without accurate testing tools, designs for PCBs, cables, and interconnects risk failing under real-world data loads.

Rohde & Schwarz claims that the new R&S ZNB3000 vector network analyzer addresses these needs with models extended to 32 GHz, 43.5 GHz, and 54 GHz. By covering frequencies up to 54 GHz, the analyzer gives engineers the capability to test high-speed PCBs, cables, and interconnects critical for AI infrastructure. It also expands testing to RF components for 5G, 6G, Wi-Fi, and satellite communications in the Ka and V bands.

Key performance features support both speed and precision:

  • High dynamic range up to 150 dB
  • Very low trace noise, below 0.0015 dB RMS
  • High output power for accurate measurement at higher frequencies
  • Ultra-fast measurement speed for high throughput and lower test costs
  • Low start frequency of 9 kHz for precise time-domain analysis
  • Flexible upgrade path, so customers can start with a base model and extend frequency later

These capabilities make the R&S ZNB3000 suitable for production and research environments. Engineers working on SatCom components such as filters, mixers, amplifiers, switches, and beamformers, or those validating next-generation interconnects for AI and cloud infrastructure, can use the analyzer to accelerate design cycles while maintaining accuracy.

By combining wide frequency coverage, fast results, and a scalable platform, the analyzer provides the tools needed to meet the demands of emerging technologies across data centers, wireless systems, and satellite communications.
