Checking Antenna Spectra (EMPTY)

This is typically performed in either swlevel 2 or swlevel 3, with the methodology differing between the modes. This is a sample of commands used while in swlevel 3, 

user1@lcu$ # Initialisation
user1@lcu$ swlevel 3
user1@lcu$ rspctl --bitmode=8
user1@lcu$ 
user1@lcu$ # Beamforming
user1@lcu$ # LBA mode 3
user1@lcu$ beamctl --antennaset=LBA_OUTER --band=10_90 --rcus=0:191 --subbands=0:487 --beamlets=0:487 --anadir=0,0.7853982,AZELGEO --digdir=0,0.7853982,AZELGEO
user1@lcu$ # HBA mode 5
user1@lcu$ beamctl --antennaset=HBA_JOINED --band=110_190 --rcus=0:191 --subbands=0:487 --beamlets=0:487 --anadir=0,0.7853982,AZELGEO --digdir=0,0.7853982,AZELGEO
user1@lcu$ # HBA mode 7
user1@lcu$ beamctl --antennaset=HBA_JOINED --band=210_250 --rcus=0:191 --subbands=0:487 --beamlets=0:487 --anadir=0,0.7853982,AZELGEO --digdir=0,0.7853982,AZELGEO
user1@lcu$ 
user1@lcu$ # Shutdown
user1@lcu$ swlevel 0

After initialisation, rspctl --stati can be run in a separate shell (or the same shell if the beamctl commands are run in the background) and will plot the SST data for visual inspection. If an antenna spectra is looking suspicious, the RCUs used for the beamctl commands can be used to limit the range of antennas to make it easier to try down the misbehaving antenna.
