Using the UBX board on the x310 and the lo leakage is the same amplitude if not higher than the signal being played with rfnoc samples from file.

So I ran the calibration functions but it doesn't seem to be using the created files since I did not notice a difference. Is there a function call or setting in cpp I need to add? I thought it would be automatic. Using uhd 4.2 with X310. -------------- next part -------------- A message part incompatible with plain text digests has been removed ...

I'll note that most of the DC-offset compensation is done in a daughtercard-independent way and doesn't rely on the CAL functions as far as I know--there's a continuous "DC offset removal" function in the FPGA. When you say "noticeable" what is the magnitude we're talking about? ------------------------------ Subject: Digest Footer _______________________________________________ USRP-users mailing list -- [email protected] To unsubscribe send an email to [email protected] ------------------------------ End of USRP-users Digest, Vol 145, Issue 55 *******************************************
