In the transmit direction, the 5G signals generated in the IF band by the R&S SMW200A are converted to the FR2 range up to 44 GHz. This ensures that high transmit power is generated where it is needed. On the receive side, the R&S FE44E converts the FR2 signal at the antenna inputs to the IF band, sending it with minimal attenuation to the R&S FSVA3000 for analysis. This solution is suitable for test and measurement systems in production environments.
Rohde & Schwarz has developed a high-performance, scalable, server-based analysis platform for speed-optimized testing in 5G base station production. The R&S SMBV100B vector signal generator and R&S FSVA3000 spectrum analyzer are used as RF test solutions. Powerful R&S QuickStep software is used to automatically control test setup and verify results. The solution utilizes a 10 Gigabit Ethernet network, where the combination of this server-based strategy and parallel processing enables very high measurement speeds. The combination of the R&S SMBV100B and R&S FSVA3000 is also ideal for flexible testing of WLAN, cellular, and IoT components and devices in verification, production, and R&D.
Rohde & Schwarz now offers a new test and measurement solution for base stations and small cells that enables multichannel measurements up to 4x4 MIMO on 5G transmissions in the FR1 range. The solution consists of the R&S SMW200A signal generator, two R&S SGT100A vector RF sources, the high-performance R&S RTP164 oscilloscope used as a measurement receiver, and the 5G analysis options of the R&S VSE vector signal explorer software running on a laptop.
The R&S SMW200A generates 3GPP-compliant 5G signals that can be transmitted over up to four channels using the two additional vector RF sources. The oscilloscope provides phase-coherent acquisition of all four signals, a basic prerequisite for multichannel measurements. The R&S RTP164's integrated, hardware-accelerated, digital buck converter mixes the signals and downconverts them to baseband in real time. The R&S VSE software performs measurements according to 3GPP specifications. Users can also perform specific MIMO measurements and flexibly compile the results. The solution is suitable for testing during the development and verification of 5G base stations.
