I work with a USRP X310 and two CBX-120 daughterboards. I would like
to calibrate the daughterboards according to the page
https://files.ettus.com/manual/page_calibration.html on USRP Hardware
Driver (UHD) manual. After applying the utilities for
self-calibration, with or without 50 Ohm terminators attached to the
RF ports, I see no difference with “ignore-cal-file” enabled or
disabled. I transmitted both a single tone and an OFDM-like waveform
at Low-IF mode. There was no difference in terms of LO leakage or IQ
imbalance. I am not sure if I missed something to do. Do you have any
ideas?
Please let me know if you need any specific information to help me.
Thanks!

Could you confirm that it placed CAL files in your ".uhd/cal" directory
under your home directory?
