    Devices

    RECV

    The recv == Device("LTS/RECV/1") device controls the RCUs, the LBA antennas, and HBA tiles. Central to its operation are the masks:

    • The RCU_mask_RW attribute is an array of bool[N_RCUs]. It controls which RCUs will actually be configured, when fields referring to RCUs are set. Any RCU for which the mask is False will not be configured when RCU control points are set.
    • The Ant_mask_RW attribute is an array of bool[N_RCUs][N_Antennas_per_RCU]. It controls which antennas will actually be configured, when fields referring to antennas are set. Any antenna for which the mask is False will not be configured when antenna control points are set.

    Typically, N_RCUs == 32, and N_Antennas_per_RCU == 3.

    SST and XST

    The sst == Device("LTS/SST/1") and xst == Device("LTS/XST/1") devices manages the SSTs (subband statistics) and XSTs (crosslet statistics), respectively, that are emitted by the Uniboards in SDP. By default, each device configures the statistics to be streamed to itself (the device), from where the user can obtain them.
