Rohde & Schwarz FSL3

This Spectrum Analyzer is a wide band, very sensitive receiver.

It works on the principle of super heterodyne receiver to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities.

The received frequency spectrum is slowly swept through a range of pre selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of this unit.

The CRT displays received signal strength (y-axis) against frequency ( x-axis).

This unit is an extremely 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.
