FSEB20 Rohde & Schwarz Spectrum Analyzer


The FSEB20 is a 7 GHz Spectrum Analyzer from Rohde & Schwarz. A spectrum analyzer measures the power of spectrums of known and unknown signals. Spectrum analyzers collect information such as the magnitude of an input signal compared to its frequency. As a frequency analyzer, spectrum analyzers’ main use is to document and analyze electrical input signals as well as spectral compositions of other signals.

The Rohde & Schwarz FSEB20 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. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
