Rohde & Schwarz introduces the all-new R&S FSW analyzer with enhanced analysis bandwidth and RF performance

When faced with test and measurement challenges in the field of aerospace and defense (A&D), automotive or 5G testing, engineers need tools whose performance they can rely on. Instruments such as the R&S FSW high-end signal and spectrum analyzers are ideal for measurements in such applications.

The R&S FSW analyzers are used for measurements in applications, such as 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 product can also be used to characterize RF components such as power amplifiers.

Rohde & Schwarz Introduces All-New FSW Signal/spectrum analyzer


The company announced that it has further improved the 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.

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 for seamless real-time analysis

800 MHz instead of 500 MHz bandwidth is now available for real-time analysis. The new R&S FSW models claim to 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 R&S FSW signal and spectrum analyzers will be presented to the public at European Microwave Week in Madrid from September 25 to 27, 2018, and are available now from Rohde & Schwarz. For more details, click here.
