            [NOEMAONLINE\] BASEBANDS [SelectionCode] [Mode] [/RECEIVER Irec]

        Assign  a  mode  to a given baseband and switch it on.  Correlator modes
        are called using their implementation number. Mode 1 offers 64 low reso-
        lution  chunks  and  up to 16 high resolution chunks in a baseband; High
        resolution chunks are selected with the SPW command.  Mode 3  offers  64
        chunks with a channel spacing of 250kHz; SPW cannot be used on basebands
        using Mode 3.  Mode can also be OFF to switch the corresponding correla-
        tor unit OFF.  Mode 2 of PolyFix is VLBI, not available in ASTRO.

        The selection is done through 0 to 3 character codes to indicate the po-
        larization, sideband and baseband (1 character each).

        Example:
        BASEBAND HUO 1 /RECEIVER 1: will set the mode 1 to the outer baseband of the
                                    sideband in polar H, for the Band 1 tuning.

        Option /RECEIVER can be omitted in ASTRO as long as multi  band  is  not
        supported.
