- The R&S FSW series signal and spectrum analyzer from Rohde & Schwarz incorporates a new front end that enables it to perform EVM measurements with a high level of accuracy on broadband modulated signals in the millimeter wave (mmWave) frequency range.
The error vector magnitude (EVM) is one of the main parameters used to characterize the performance of a digital transmitter or receiver. EVM measurements are currently essential for the development of 5G base stations and components operating at FR2 frequencies as well as for high frequency satellite applications.
Since its market launch, the R&S FSW signal and spectrum analyzers has continuously evolved both in hardware and software to meet new requirements for frequency, bandwidth, modulation, sensitivity and streaming. The latest improvements to its front end and the optimization of its hardware interface for frequencies in the microwave range above 26 GHz enable the R&S FSW analyzer to perform measurements with greater accuracy. It thus meets the test requirements of high-end communication components or systems such as 5G NR FR2 or IEEE 802.11ay / ad chipsets, amplifiers, user equipment and base stations.
With its 8.3 GHz internal analysis bandwidth for characterizing broadband communication components and systems, the R&S FSW has the analysis bandwidth required for 5G NR testing. It offers measurement capabilities for in-depth analysis of the physical layer. This makes it possible to validate all the physical layer specifications defined in the standard.
The new R&S FSW-B24U Enhanced Dynamic Front End (EDFE) upgrade is integrated as standard in the new R&S FSW43, R&S FSW50 and R&S FSW67 models, which cover frequency bands up to 43.5 GHz, 50 GHz and 67 GHz respectively. Many of the R&S FSW series signal and spectrum analyzers already in use will also be able to take advantage of this feature with the R&S FSW-B24U upgrade option.
