outliers in ru_metrics (gnb)

Issue Description

When I try to launch my gnb with sudo gnb -c ./srsRAN_Project/configs/gnb_E316.yml, everything seems to launch correctly, but nothing is displayed when I use t and I get strange values when I use ru_metrics

Setup Details

I'm using an ubuntu 22.04 server on a proxmox virtual machine with open5gs up and runing and an ANTSDR E316 radio device

Expected Behavior

ru_metrics should display logical values and t should display something (I suppose)

Actual Behaviour

t doesn't display anything, ru_metrics return : | ------------------- TX ------------------ | ------------------- RX ------------------ | | Avg. power | Peak power | PAPR | Clipping | Avg. power | Peak power | PAPR | Clipping | | nan | -379.3 | nan | nan | nan | -379.3 | nan | nan |

Additional Information

here is my gnb_E316.yml
