Issues of design and practical usage of the analyzer of concentrated additive noise on the base of the signal receiver of the ionosphere oblique sounding with linear frequency modulation are considered. Ratio for amplitude characteristic of the analyzer is being under definition. Results of laboratory tests of the analyzer maquette are provided: experiment conducting conditions and estimation method of the analyzer characteristics under the experimental test data is described. On the basis of examples of additive noise as the signals with continuous waves and amplitude modulation real efficiency of the analyzer within measuring the concentrated noise spectrum parameters is shown. Besides, correctness of the function for resolution characteristic of the analyzer in the frequency area that is developed analytically is confirmed on experimental basis.
