This paper presents the design of a low-cost real-time (RT) virtual spectrum analyzer. The premises for the creation of the RT instrumentation are introduced. The details of the virtual analyzer design are presented. Tests of the instrument, as well as the comparison between the time analysis of the classical and virtual spectrum analyzers, are conducted. Conclusions about the future prospects of such a design approach are iterated.
