Programmable Active Crystal Filters with crystal filter based filtering system, and a software programmable running, 1.25 KHz steps.
The following picture is the ‘before and after’ spectrum situation.
The left diagram is a screenshot of a standard field spectrum measurement, in which the reception signal is marked in green. The diagram on the right is a screenshot of the same spectrum at the output of an Active Crystal Filter. Note how the presence of an active Crystal Filter provides an outstanding non-desired spectrum rejection, enhancing the overall reception quality and increasing the system coverage area.
