Signal generators feature improved EVM performance
Rohde & Schwarz has upgraded its R&S SMW200A vector signal generator and its mid-range counterpart, the R&S SMM100A.
With enhancements in error vector magnitude (EVM) performance, the evolved R&S SMW200A is a choice for both 5G NR FR3 research and high-demand RF applications like power amplifier testing.
The instrument now also includes a new RF linearisation software option, which uses digital pre distortion to optimise EVM at high output power. The R&S SMM100A has also been upgraded with improved EVM capabilities.Caption: With its improved EVM performance, the evolved R&S SMW200A is ideal for high demand RF applications.
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 best-in-class 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 -53dB for an IEEE802.11be signal with a bandwidth of 320MHz.
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.
