Rohde & Schwarz has upgraded its industry leading R&S SMW200A vector signal generator and its midrange counterpart, the R&S SMM100A. With significant enhancements in error vector magnitude (EVM) performance, the evolved R&S SMW200A is a robust choice for both 5G NR FR3 research and high demand RF applications like power amplifier testing. The instrument now also includes a new RF linearization software option, which uses digital pre distortion to optimize EVM at high output power. The R&S SMM100A has also been upgraded with improved EVM capabilities.
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 linearization software option R&S SMW-K575, which utilizes digital pre distortion technology to optimize 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 linearization: Rohde & Schwarz offers retrofit options through a simple service and calibration process.
Gerald Tietscher, Vice President of Signal Generators, Power Supplies and Meters at Rohde & Schwarz, says: “With increasing data rates and modulation scheme complexity, achieving low EVM is critical for ensuring stability and robustness in wireless connectivity applications. The latest evolution of our R&S SMW200A and R&S SMM100A vector signal generators is a testament to our commitment to making our art
of signal generation even better. With their superior RF characteristics and exceptional EVM performance, these instruments are a pivotal resource for handling the requirements of the most advanced test applications.”
