Further results have been achieved towards an observing band width of
1 GHz. An IF processor which allows the use of the two 512 MHz
filter banks as one unit of 1 GHz has been tested and installed. The
system is not yet usable at 1 GHz for observations due to other
restrictions (warm IF amplifier chain, down converters). The
processor logically divides the two 512 MHz filter banks in 4 units
of 
1 MHz each. In the future the four units can be
connected individually or in combinations to different receivers, or
can be used as one backend with a 1 GHz bandwidth. At the moment the
observers will not notice any difference with the old setup of two
filter banks. The full flexibility of the system can be used once the
software will be able to support all available options.
