- Rohde & Schwarz has upgraded its R&S SMW200A series vector signal generator and its mid-range counterpart, the R&S SMM100A series.
- The R&S SMW200A generator family now incorporates a new RF linearization software option, which uses a digital pre-distortion process to optimize the error vector magnitude (EVM) at high output powers.
- The EVM capabilities of the R&S SMM100A generator have also been enhanced.
According to Rohde & Schwarz, with significant enhancements in error vector magnitude (EVM) performance, the evolved R&S SMW200A is a suited for both 5G NR FR3 research and high demand RF applications like power amplifier testing.
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 linearization software option R&S SMW-K575, which utilizes digital pre distortion technology to optimize EVM at high output power. This ensures, according to the German manufacturer, high accuracy and stability, even for complex modulation schemes in the entire frequency range.
These 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 linearization. Rohde & Schwarz offers retrofit options through a simple service and calibration process.
