Set LO offset in the srsue config file?

[matth3wh]

Hey everyone! Looking for a way to set an LO offset in srsRAN 4g. I see that in 5G it is pretty straightforward: srsran/srsRAN_Project#111.

If there is not a simple config file change to make in srsRAN 4G, could someone provide advice on how to make the LO change in UHD directly? I see srsRAN can pass initialization arguments to UHD, but I don't see any available that pertain to LO offset.

Thanks!

Simply pass "lo_freq_offset_hz=X" to the initialization arguments for UHD in the UE or eNB config file.
