The article deals with topical issues of today use analog-to-digital receiving and processing devices (ATSPO) radio signals to control congestion of the frequency spectrum, the detection and analysis of new emissions, determining the location of their sources, as well as identifying unintended or specially organized channels of information leakage. To improve the effectiveness of the proposed ATSPO provide frequency agility operating range station, without derating transceiver operation. In particular, the provision of specific dynamic and spectral characteristics, receives by constructing a tandem digital frequency synthesizer (TSSCH). In computer design stations developed the concept of the two ring TSSCH with automatic compensation of frequency distortion on modern element base. In addition, the analysis of amplitude-frequency modulation characteristics of the proposed scheme, as well as the analysis of the reaction of the proposed scheme in the parasitic increment the reference oscillation phase. We obtain the modulation transfer function of the proposed scheme and the defined conditions of sustainability of the angle modulation. Thus, the use of two digital frequency synthesizer annular in design decision error-correcting transceiver provides frequency agility over the operating range of wavelengths with angle modulation, without impairing its essential characteristics.
