hi, you have to add `clock` parameter to your config: ``` ru_sdr: clock: external ```

could you change `sync` to `default`. What is the spec of the UE PC (cpu, and memory)?

hmm, strange, the setup runs over the air or RF cables? did you try to tune TX/RX gains?

@ruedagarcialaura any update on this issue?

probably RPi is too slow for 20MHz, you could try to tune the CPU affinities (`worker_cpu_mask` and `sync_cpu_affinity`), see here: https://github.com/srsran/srsRAN_4G/blob/master/srsue/src/main.cc#L265-L270, but not sure if it will help. also you...

@shahid2636 do you have gpsdo module inside your b210? Is the gps clock locked?

did you run this script on the gnb PC? https://github.com/srsran/srsRAN_Project/blob/main/scripts/srsran_performance Also, could you share the details of the PC? (cpu, ram?)

Please try lock the gps clock and try again.

could you share the configs you use?

could you check whether this works? https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html#usrp-x300-x310
