FSW with enhanced analysis bandwidth and RF performance

The well-established family of Rohde & Schwarz (R&S) FSW high-end signal and spectrum analyzers is used for measurements in various applications, for example in wireless communications device testing for 5G and Wi-Fi, in radar analysis in the automotive and A&D sectors and in satellite system testing. The signal and spectrum analyzers can also be used to characterize RF components such as power amplifiers.

The company has further improved the market-leading performance of the R&S FSW family. The new R&S FSW features up to 10 dB lower phase noise compared with the previous models, which is extremely important in applications such as troubleshooting the modulation of 5G signals in the microwave range. The new R&S FSW analyzers above 26.5 GHz offer an internal analysis bandwidth of 2 GHz. Now users can analyze wideband signals from radar systems or 802.11ad Wi-Fi signals without requiring an external digitizer such as an oscilloscope in the test setup.

The R&S FSW can also analyze bandwidths greater than 2 GHz, a feature that may be necessary for automotive radar or 5G applications. When performing measurements with an R&S FSW43 or R&S FSW85, the bandwidth can be extended up to 5 GHz using an R&S RTO2000 oscilloscope.

800 MHz instead of 500 MHz bandwidth is now available for real-time analysis. The new R&S FSW models process the measurement signals twice as fast as before and perform more than two million FFTs per second. They have a 100 percent probability of intercept of detecting and accurately measuring signals with a minimum duration of just 0.46 µs. Consequently, all signal details are detected without gaps. This is a crucial feature for transient analysis and when troubleshooting high-frequency applications.
