Description: In this article there has been suggested a gain-frequency characteristics identification method for measuring devices which could be modelled with an oscillating type dynamic link and which are used for vehicle testing. Both the advantages and disadvantages of this method have been considered. There have been suggested some optimizations for this method. Also there have been estimated the uncertainties which took place during the measuring devices parameters identification such as time constant and attenuation factor. The ways of reducing these uncertainties have been suggested.
