The RFX400_MIMO_B will do what you want. You can find out what version
you have by running print-db in the usrp/host/apps directory. If you
have the plain RFX400, you can modify it to the MIMO_B version by moving
some resistors.
The early RFX400's sold were the regular version, but all shipping
recently are the MIMO_B version.
