Server based production tests
For speed-optimized production tests of 5G base stations, Rohde & Schwarz has developed a scalable, high-performance server based testing analysis platform. The SMBV100B vector signal generator and the FSVA3000 spectrum analyzer are used as RF test systems. The powerful QuickStep test executive software is used to automatically control the test setup and verify test results. The setup uses a 10 Gigabit Ethernet network, where the combination of the server based approach and parallel processing enables extremely high measurement speeds. The infrastructure consists of commercially available components. The combination of the MBV100B and the R&S FSVA3000 is also ideal for flexible testing of WLAN, cellular and IoT components and devices in R&D, verification and production.
Cross-channel measurements with up to 4x4 MIMO
Rohde & Schwarz also offers a new test system for base stations and small cells that enables cross-channel measurements up to 4x4 MIMO on 5G transmissions in the FR1 range. The system consists of the SMW200A signal generator, two SGT100A vector RF sources, the RTP164 high-performance oscilloscope used as a measuring receiver, and the 5G analysis options of the VSE vector signal explorer software running on a laptop.
The SMW200A generates the 3GPP-compliant 5G test signals, which can be transmitted on 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 cross-channel measurements. The integrated hardware-accelerated digital downconverter of the RTP164 mixes the signals down to the baseband in real time. The VSE software performs measurements in line with 3GPP specifications. Users can also perform MIMO-specific measurements and flexibly compile the test results. The system is suitable for tests during the development and verification of 5G base stations.
