Rohde & Schwarz Introduces All-New FSW Analyser

Further Enhancement of Proven Family of High-End Products

Rohde & Schwarz announced on 25 September that its well-established family of FSW high-end signal and spectrum analysers – widely used in applications ranging from radar analysis to satellite system testing – now features enhanced analysis bandwidth and RF performance.

All FSW models with a maximum input frequency of 26.5 GHz and above are now available with a 2 GHz internal analysis bandwidth option and an 800 MHz bandwidth option for real-time analysis. Users will benefit from a new look and feel, with a new operating concept and an SCPI recorder for remote controlled test sequences. The analysers also feature up to 10 dB lower phase noise compared with previous models – extremely important in applications such as troubleshooting the modulation of 5G signals in the microwave range.

Internal analysis bandwidth of 2 GHz means that users can now analyse wideband signals from radar systems or 802.11ad Wi-Fi signals, without requiring an external digitiser such as an oscilloscope in the test setup. The FSW can also analyse bandwidths greater than 2 GHz, a feature that may be necessary for automotive radar or 5G applications. When performing measurements with an FSW43 or FSW85, the bandwidth can be extended up to 5 GHz using an RTO2000 oscilloscope.

800 MHz for seamless real-time analysis, instead of 500 MHz bandwidth, is now available for real-time analysis. The new 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.

The embedded SCPI recorder to automate test environments makes it very easy to create automated test sequences. The user operates the analyser as usual; the SCPI recorder records all relevant settings and converts them into a script for controlling the analyser.

The FSW now has a capacitive touchscreen and can be operated as easily as a smartphone. The redesigned operating concept and user interface allow users to take full advantage of this modern operating method. The company will unveil the new range of FSW at European Microwave Week in Madrid from 25-27 September.
