Key Facts
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.

An SSB of 103 dBc/Hz at an offset frequency of 10 kHz, a
TOI of typ. +10 dBm, resolution bandwidths from 10 Hz to 3 MHz and a DANL of
-145 dBm make the R&S FSL comparable to analyzers of higher classes. 5 dB
step attenuators and an optional preamplifier optimize the dynamic range. |
