A new 16-channel radiometry system has been designed and manufactured for the electron Bernstein / cyclotron wave emission (EBE / ECE) experiments. For EBE studies, based on EBW-X-O mode conversion, radiometry in Ka-band (26.5 - 40 GHz) will be used which corresponds to the fundamental EC harmonics for the low-Bt (Bo ~ 1.2 T) tokamak operation. Alternatively, an E-band antenna and front-end (60 - 73.5 / 76.5 - 90 GHz) will be used with the same 16-channel receiver for the conventional second harmonics ECE diagnostics. In the contribution the design of the system is described as well as the initial testing measurements on tokamak COMPASS.
