+Beam
+====================
+
+The ``beam == DeviceProxy("STAT/Beam/1")`` device sets up the beamforming on the station:
+
+- The HBA tiles in RECV need *analog beamforming* to combine their 16 antennas into a single input for the RCU,
+- THe LBAs or HBA tiles need *digital beamforming* in SDP to combine their signals into beamlets.
