Does srsRAN Project support X310?

[pengnist]

We are exploring using X310 for gNB and ran into this error:

We have an external octoclock that provides 10MHz reference clock and 1PPS to X310, and we added time_source = external and clock_source = external to the yaml file:

Does srsRAN Project support X310 for gNB radio? If so, is there any specific configuration we should make to the yaml?

Thanks

Hi @pengnist, thanks for reporting this. Yes, the X310 is supported. I also get this warning, but so far the gNB keeps working normally.

with 60 dB attenuation better you transmit high power like tx_gain=30 and rx_gain 20

Thank you! I was able to make gnb work with X310, when the srsue uses B210. However, the connection cannot be established when srsue uses X310. If you have a working pair with X310s, do you mind sharing the conf file for your srsue?

The [rf] section of my ue.conf is:

freq_offset = 0
tx_gain = 30
rx_gain = 5
srate = 11.52e6
nof_antennas = 1

device_name = UHD
device_args = type=x300,addr=192.168.13.2,dboard_clock_rate=11.52e6,time_source=external,clock_source=external
time_adv_nsamples = auto

I also tried changing the time_adv_nsamples from 50 to 350 with no luck.

Please kindly let me know if any specific config needs to be applied. Thanks

Could you add the following to the UE config and see whether it works with x310?

lte_sample_rates = true

If having issues staying connected using two USRP X310, see my #343, and this line lead to it not connecting at all.

@pengnist please check #343
