R&S FSW signal and spectrum analyser with Enhanced Dynamic Front End

Error vector magnitude (EVM) is one of the main parameters to characterise the performance of a digital transmitter or receiver. The R&S FSW signal and spectrum analyser from Rohde & Schwarz is suitable for high-end measurements requiring high precision; its enhanced front end now continues the path of innovation with EVM measurement for wideband modulated signals in the mmWave range. This makes the product useful for testing any high-end communication component or systems, including 5G NR FR2 or IEEE 802.11ay/ad chipsets, amplifiers, user equipment and base stations.

With frequency, bandwidth, modulation, sensitivity and streaming requirements becoming more demanding, Rohde & Schwarz has been developing the R&S FSW hardware and software over the years to meet and exceed changing performance needs. This includes enhancements to the modified front end as well as microwave hardware optimised for frequencies above 26 GHz.

Featuring a wide internal analysis bandwidth that allows the characterisation of wideband components and communications systems, the signal analyser is suitable for 5G NR testing. Its measurement applications are designed to simplify and speed up in-depth analysis of the physical layer, allowing testing at high frequencies and wide measurement bandwidths. Users can cover all the physical layer options specified in the standard with good RF performance.

With the R&S FSW-B24U Enhanced Dynamic Front End (EDFE) upgrade of the R&S FSW, Rohde & Schwarz addresses the challenging requirements for EVM performance in the mmWave range. R&S FSW43, R&S FSW50 and R&S FSW67 models now ship with the enhancements as standard; the R&S FSW-B24U can also be ordered as an upgrade to many R&S FSW signal and spectrum analysers already in use.
