    DBBC2 (4) means  4 ADB2 + 4 CORE2

    DBBC2 (4*) means 2 ADB2, 1ADB1 + 4 CORE2

    DBBC2 (4-) means  4 ADB2 + 2 CORE2

    DBBC2 (2) means 2 ADB2 + 2 CORE2

    Available modes are DDC Mode: 32 MHz x 16 channels x 2 pols = 2 x 512 MHz (requiring 4 CORE2) or 64 MHz x 8 channels x 2 pols = 2 x 512 MHz

    R1002 DAS can do 32 MHz x 16 channels = 512 MHz  [analog backend]

    a) Only 400 MHz of IF bandwidth

    b) Only 150 MHz of IF bandwidth

    c) Only 390 MHz of IF bandwidth

    d) Only 160 MHz of IF bandwidth

    e) RCP only

    Ro70 K-band recording data rate limited by bandwidth (70MHz per pol)

    Ro34 Q-band recording data rate limitedby bandwidth (70MHz per pol)
