R&S FSW spectrum analyzer significantly updated

The Rohde & Schwarz spectrum analyzer has been a mainstay of the RF test and measurement scene. It has provided effective service for a number of years for everything from 4G to 5G, wireless systems to radar analysis and much more.

Now this well-established family of R&S FSW high-end signal and spectrum analyzers has significantly upgraded the range improving its RF performance, analysis capability and usability.

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. Internal analysis bandwidth of 2 GHz.

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 real-time analysis bandwidth

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 % 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.

SCPI recorder to automate test environments

It is very easy to create automated test sequences with the R&S FSW analyzer's embedded SCPI recorder. The user operates the analyzer as usual; the SCPI recorder records the all involved settings and converts them into a script for controlling the analyzer.

As easy to use as a smartphone

The R&S FSW now has a capacitive touchscreen and can be operated like a smartphone. The redesigned operating concept and user interface let users take full advantage of this modern operating method.

The new FSW appears to have been significantly upgraded and wil enable the series to continue its leading position in the marketplace.
