New R&S vector signal generators feature significantly improved EVM performance
Rohde & Schwarz has introduced the latest evolution of its two vector signal generators, the signature R&S SMW200A for the most demanding applications, and its midrange counterpart, the R&S SMM100A. Besides a redesigned front panel and user interface, the R&S SMW200A has been equipped with modified microwave hardware for enhanced error vector magnitude (EVM) performance as well as higher output power in the frequency range above 20 GHz. This addresses the demands of 5G NR FR2 research and RF component and module testing.
This upgrade comes with an RF linearisation software option R&S SMW-K575, which utilises digital pre‑distortion technology to optimise EVM at high output power. This ensures high accuracy and stability, even for complex modulation schemes in the entire frequency range.
These key upgrades also extend to the R&S SMM100A, the midrange counterpart of the R&S SMW200A. The R&S SMM100A also comes with a new low phase noise option, R&S SMM‑B709. With this option, the R&S SMM100A can provide, for example, an EVM performance better than –53 dB for an IEEE802.11be signal with a bandwidth of 320 MHz.
Customers with previous models of the R&S SMW200A or R&S SMM100A can also benefit from the new performance enhancements offered by R&S SMx-K575 RF linearisation: Rohde & Schwarz offers retrofit options through a simple service and calibration process.
