This paper presents the results of the commissioning of the ROACH2-based backend at the Sardinia Radio Telescope. New observations of the galaxy cluster 3C129 in the frequency range 6000-7200 MHz are used to image the large-angular-scale emission at high-frequency of the radio sources located in this cluster of galaxies, including the tailed radio galaxy 3C129 at its center. These data were used, in combination with literature data at lower frequencies, to derive the variation of the synchrotron spectrum of 3C129 along the tail of the radio source in order to infer its radiative age and its speed.
