I am using a USRP N210. When i set the subdev spec for my basic RX daughterboard as "A:A A:B" I can receive two channels. However, if I try to do something similar for the basic TX I get an error like "The user specified 2 channels, but there are only 1 tx dsps on mboard 0." I assume this is because there is only one DUC chain in the N210. Is there a way to modify this so that I can have two DUC chains in the same way that I have two DDC chains?
Thanks,
Anisha
