The high-performance Rohde & Schwarz FSW signal and spectrum analyzer was developed to meet demanding customer requirements. Offering low phase noise, wide analysis bandwidth and straightforward and intuitive operation, the analyzer makes measurements fast and easy.
The high-performance R&S®FSW signal and spectrum analyzer helps engineers accomplish the most demanding tasks. Its wide internal analysis bandwidth allows the characterization of wideband components and communications systems. Its unparalleled phase noise facilitates the development of high-performance oscillators such as those used in radars. A state-of-the-art multitouch display with gesture support ensures straightforward and intuitive operation. An embedded SCPI recorder enables easy creation of executable scripts.
The R&S®FSW offers up to 8.3 GHz analysis bandwidth for measuring wideband-modulated or frequency agile signals like those used in the new 5G New Radio standard or in automotive and pulsed radars.
