There is a known issue where the target levels loaded by the DBBC through load=dbcc... are incorrect. For now, the workaround is to specify the target power levels in the ifdsx section of the proc file. | There is a known issue where the target levels loaded by the DBBC through load=dbcc... are incorrect.
