Subdevice0 is the antenna A, Subdevice1 is the antenna B. You can use 
both subdevice 0 and 1 at the same time on two different ddc inputs and 
tune them separately. These subdevices are used as real inputs, and the 
Q inputs to the ddc are set to zero.

The third possibility is to use subdevice2 which treats the antenna A 
and B as a single complex input (I and Q), and connects them to the I 
and Q inputs of the DDC input0. When using subdevice2, you cannot use 
subdevice 0 and 1.
