DBBC3 - A full digital implementation of the VLBI2010 backend


G. Tuccari, INAF - Istituto di Radioastronomia, Noto - Italy


The project of the third version for DBBC backend system implementation is presented. This system is able to fully implement in digital the functionalities required by a complete VLBI2010 backend, including the sky frequency conversion in the entire range 2-14 GHz, so avoiding any need of an analogue down-conversion to be used as preprocessor of a polyphase digital filter bank. The architecture and adopted methods are described.

This conference is sponsored by the National Geographical Institute of Spain (IGN) and the International VLBI Service for Geodesy and Astrometry (IVS).
