Description
The selective optical to RF converter has a filter that separates each wavelength
and directs it to an independent circuit with a photosensor, which obtains the RF
signal that carries. The RF signal obtained for each wavelength passes to a band
switch.
The band switch receives a signal and converts it to a frequency within the RF
band (65 — 2150 MHz). In the case of a terrestrial / cable signal the signal is
not converted since that signal is within the RF range. After the conversion, the
RF signal output is connected to the analyzer input connector and the
measurement is performed in the usual way to an RF signal. In the conversion,
bear in mind that for every unit of optical attenuation (one dB), occurs two dBs
of power loss in RF. As an example, every 3 dB of optical attenuation for each
splitter are equivalent to 6 dB of power loss for RF.
