The AD9371 API has a call to disable the digital DC offset correction: https://github.com/EttusResearch/uhd/blob/9f03f6399dcc7b1f3acf7d9595554b0d96884ca6/mpm/lib/mykonos/adi/mykonos.h#L270 But it isn't exposed via a higher layer call. The Mykonos API is called in this file: https://github.com/EttusResearch/uhd/blob/9f03f6399dcc7b1f3acf7d9595554b0d96884ca6/mpm/lib/mykonos/ad937x_device.cpp You'd need to modify the file and rebuild MPM, load it onto the N310, then restart the uhd hardware service on the N310. Not sure how much more quadrature error correction (QEC) runs non-digitally on the device. This is probably the hackiest way to just try it out. Brian
