The Spectrum Analyzer R&S FSL is an extremly lightweight and compact analyzer with a wide range of applications in development, service and production. It offers functions that up to now have only been provided by high end spectrum analyzers and therefore has an excellent price/performance ratio.

The R&S FSL is the only instrument in its class that provides a tracking generator up to 6 GHz and a demodulation bandwidth of 20 MHz. The graphical user interface shows the R&S FSL's similarity to the R&S FSU and the R&S FSP at a glance
