There is a graphical scope that allows to debug signals on the physical layer. It is located in openair1/USERSPACE_TOOLS/SCOPE. It can be compiled using "make chbch".(Note: compiling the Scope requires the libforms libraries - sudo apt-get install libforms-dev)
transport_channel: 0=CHBCH 1=RACH 2=DCCH/SACH 3=MRBCH nb_tx_antennas: number of Tx antennas (usually 2 for CBMIMO1) chsch_index: only used when transport_channel==0 (CHBCH)
For the LTE branch use the LTE scope. Use "make lte" for the UE and "make lte_ul" for the eNb. Start it with "./lte_scope" and "./lte_scope_ul" (no arguments needed). See attachement on this page for a description of the scope.
A proc filesystem is created by the openairinterface modules.
