# Remarks:
# * No need to write subband and beamlet mappings because FW default is ok for CB0:
# . R_sub = hex/rsub_range_64_448_1* in apertif_unb1_bn_filterbank_reorder.vhd
# . R_beam = hex/rbeam_300MHz_37CB in node_apertif_unb1_fn_beamformer.vhd
# . R_beamout = hex/reorder_matrix* is transparent in node_apertif_unb1_fn_beamformer_transpose.vhd
# User parameters # User parameters
CUNB=14 # central UniBoard determines the iblet and thus via Rsub the subband CUNB=14 # central UniBoard determines the iblet and thus via Rsub the subband
