The input signal is made by a single mode fibre. One can observe the spectrum on an oscilloscope screen. These optical spectrum analyzers have been designed in order to complete the experimental teaching materials (erbium doped fiber amplifier and fiber laser, wavelength multiplexing … )
This low cost equipement will also allow a full understanding of the characteristics of the spectrum analyzer : it is possible to tune the focal length of the mirrors, in order to study the resolution parameters.
