James,In the case of DC calibration for tx, we'd recommend running the dc calibration routines provided with UHD for each unit. The cal routines make it a relatively easy process.
In theory, if the average DC offset is non-zero you may be able to apply an average correction and see some improvement - but less than a per-unit calibration. I don't have have any data on hand for an average DC offset.
I'm cross-posting to the usrp-users list, which is more oriented to USRP specific questions.

Hi list, I need to compensate usrp dc offset. but the dc offset is different from unit to unit. so do I need to calibrate each unit dc offset or there is a universal value that work for each unit?
