Rohde & Schwarz has introduced a new version of its FSW high-end signal and spectrum analyzer which now supports an extended 8.3 GHz internal analysis bandwidth. This, it said, offering unequaled dynamic range and sensitivity in a one-box solution for engineers developing the latest radar and wireless communications technologies as well as future satellite systems.
Covering an input frequency range of up to 90 GHz, the company said its new R&S FSW-B8001 provides an unmatched dynamic range and sensitivity, precision and EVM performance. Equipped with the extended analysis bandwidth option and dedicated measurement applications, the signal and spectrum analyzer meets current and future test and measurement requirements for ultra wideband signal analysis across different industries. Applications for the R&S FSW include pulse measurements of aerospace and defence radar systems, satellite payload testing and amplifier pre-distortion tests. The instrument also covers chirp analysis for automotive radar and research on the next generation of wireless communication.
The trend toward higher signal bandwidth continues in virtually all high frequency applications. In radar technology, for example, wider bandwidths lead to better range resolution for object detection. When developing and verifying both radar systems and radar jammer systems, wideband acquisition makes it possible to analyze frequency hops in detail while examining different radar systems operating at different frequencies.
Increased bandwidths are the norm also in wireless communications technology, with every new technology generation requiring ever higher data throughput. For instance, the IEEE 802.11ay standard for Wi-Fi supports channel bonding, which leads to signals with bandwidths greater than 8 GHz. Suitable wideband test and measurement equipment is also needed for upcoming gigabit communications sub-THz bands, such as D-Band and G-Band, which are often named as potential frequency ranges for a future 6G wireless communication standard.
Future satellite systems will also operate with higher frequencies and wider bandwidths as bandwidths are expected to increase to 3 GHz or 5 GHz at frequencies up to 90 GHz, such as for high throughput satellites designed to support terabit connectivity.
For these ultra-wideband systems, signal analysis has so far generally only been possible via a workaround. Former approaches for ultra-wideband signal analysis made use of signal and spectrum analyzers as wideband downconverters. The downconverted signals were fed into an oscilloscope, digitized and fed back to the analyzer.
In contrast, the company said its R&S FSW offers far higher signal quality and sensitivity in a user-friendly, one-box solution – combined with fully featured and signal analysis capabilities that also offer spectrum analysis functionalities.
