The Digital Base Band Converter (DBBC) is a hardware platform based on programmable logic, developed by IRA-Noto, being installed on all antennas of the EVN network. SRT will also be part of this network and therefore it will be equipped with this system for VLBI observations; as these observations will be performed during two months every year, one can take advantage of DBBC's reconfigurability to use it also during single dish observations.

In this paper we describe the porting on DBBC of a spectropolarimeter developed at Arcetri Astrophysical Observatory for a multi-feed receiver for Sardinia Radio Telescope. We will first describe the overall system and then all design modifications required  to make the device compatible with the new hardware.
