January 17, 2014. Rohde & Schwarz has expanded the analysis bandwidth for its R&S FSW high-end signal and spectrum analyzers to 500 MHz with the new R&S FSW-B500 hardware option, which is now available for all analyzers of the R&S FSW family and can therefore be used for measurements in a frequency range up to 67 GHz. The option enables new applications for the signal and spectrum analyzer in research and development. The analyzer is especially well-suited for sophisticated measurement tasks in radar or satellite applications as well as for tests on fast wireless connections such as WLAN or Beyond 4G (5G).
The large analysis bandwidth enables users to test pulse rise and fall times from approximately 3 ns or very short pulses from an 8-ns pulse width. The analyzer can therefore be used in the development of radar systems for automotive applications, for example. Users can fully record and measure radar chirps with up to 500-MHz bandwidth. Hopping sequences in frequency-agile communications systems such as tactical radios can also be easily analyzed. Researchers working on satellite applications will be able to characterize the components for the future transponder generation with up to 500-MHz analysis bandwidth. Components for microwave links can also be measured with up to 500-MHz bandwidth.
The R&S FSW now offers developers of RF amplifiers for mobile radio or WLAN the ability to measure digital predistortion of amplifiers with up to 160-MHz bandwidth, as required for WLAN 802.11ac signals, for example. In the past, measuring these kinds of wideband signals often required complicated setups consisting of a digital oscilloscope and a downconverter.
The R&S FSW-B500 option for the R&S FSW high-end signal and spectrum analyzer is now available from Rohde & Schwarz.
