Rohde & Schwarz yesterday introduced the R&S SMM100A vector signal generator and the R&S FSVA3000 signal and spectrum analyzer as solutions for improving midrange testing with best-in-class RF characteristics. The company said it is bringing laboratory performance to large-scale RF application development with the new signal generator and signal and spectrum analyzer. The instruments support up to 1 GHz of signal generation and analysis bandwidth and place an emphasis on quality measurement characteristics for generating and analyzing signals for the most advanced 5G NR devices. 

“By starting with our high-end instruments that already provide excellent measurement quality and working backwards, we can make decisions about which performance characteristics to scale back in order to bring complexity – and cost – down,” said Alexander Pabst, Vice President Wireless Communications, Rohde & Schwarz. “And as 5G continues to transition to the mass markets, the R&S SMM100A vector signal generator and the R&S FSVA3000 signal and spectrum analyzer gives our customers the best of both worlds, a purpose-built solution that is sensitive to cost, with excellent performance for the measurements that matter.”  

Both the R&S SMM100A and the R&S FSVA3000 feature what the company calls “best-in-class” EVM performance in the 28 GHz band. For example, the measured EVM of a 100 MHz 5G NR signal is less than one percent for both instruments. 

EVM influences the entire design cycle and has become an important benchmark for chip manufacturers, according to the company. Rohde & Schwarz says test instrumentation that prioritizes this measurement leads to superior components for base stations, smartphones, and other wireless devices with demanding performance, data throughput, and energy requirements. With each design iteration, the testing criteria become more specific, and manufacturers can focus their test and validation on only the most applicable measurements.
