DBBC3 Report
The DBBC unified control software was completed in the main tasks, still remaining to be added the functionality for the DDC and PFB modes,
now possible with low level commands. Completion in its first formal version and testing are under way.
Calibration functionalities are now automated and show to perform well. The entire process is realised in background. The overall speed of the control operations
will be increased.
The complete firmware available at present is the DSC full band with bw up to 4 GHz for each IF.
Activity on the firmware development was concentrated on the DDC implementation so to optimize the functionality and the number of independent bbc elements.
The GPS synchronization was added for the entire set of 8 CORE3H with a single receiver.
The new synthesizer board GCAT has been developed and is in testing phase. It allows to use additional input reference frequencies from the H-Maser (ex. 100MHz)
when this is required.
