The new date for the TBB data acquisition busy week is: Monday 30. March – Friday 3. April
The main goal of this week is to get the (MAC/SAS ???) software up to a level so that the operators can generate a (not-triggered?) data dump from the TBBs and return a single hdf5-file with all the raw-data to the user. Secondary goals are to include metadata (e.g. the antenna positions) in the file and to get a triggered data dump. (Otherwise these issues are addressed at a later time.)
Side-topics will probably be the inclusion of the metadata into the TBB files and imaging from TBB data.
Everybody who plans to attend is kindly asked to send an e-mail to A.Horneffer

Improve the TBB data acquisition so that the the following is (reasonably) conveniently possible (in decreasing importance):
(Activities at lower priority, mostly done by people not directly involved with the DAQ work.)

Task | Responsible | Status |
---|---|---|
Adjustment of initial timeout when starting up tbb2h5 to start listening for data coming at a designated port | Baehren | done (r2502) |
Resorting of incoming data blocks in tbb2h5 | Horneffer | done (r2504) |
Debugging of LOFAR_TBB: gives segmentation fault when adjusting blocksize after construction | — | pending |
Debugging of DAL routine to read string-valued attributes; after earlier changes on in some of the basic DAL functions by Joe, the retrieval of such attributes fails and therefore also causes TBB_LOFAR to crash. | Baehren | done (r2503) |
Start writing out TBB data from the oldest entry in the buffer, such that frames sent off to CEP at least leave the station in chronological order | Donker | done |
Clean up command line parameters passed to tbb2h5; some of the currently expected values appear not to even get used in TBB.cpp | bahren | pending |
Create dynamic spectrum from dump of TBB data | ter Veen, Griessmeier | pending |
Debugging of Beamformer: the retrieved weights which are applied to the data are all unity, which means that somewhere along the line values are not passed correctly | Baehren | pending |
Reduce the output speed of the TBBs so that no packages are lost | Donker | pending |
Fix tbb2h5 so that reading from a socket works | Horneffer | done (r2514) |
Fix tbb2h5 so that it can handle different dipoles. | Horneffer | done (r2518) |
