uhd_usrp_probe shows only two Antennas works #697

Closed zzystudy closed 10 months ago

zzystudy commented 10 months ago

Issue Description

when I run uhd_usrp_probe, the result shows my USRP X310 only has two Antennas works. And when I run srsran gnb, I can not receive any signal in my phone, could someone help judge whether the USRP X310 is broken?

Setup Details

Expected Behavior

I can run srsran gnb and can receive signal in my phone

Actual Behaviour

I can run srsran gnb but can not receive any signal in my phone.

Additional Information

the result of uhd_usrp_probe is:

you can use the below command to verify if your usrp is working or not.

./benchmark_rate --rx_rate 10e6 --tx_rate 10e6

It will create a loopback and display the number of trasmitted and received samples, along with other messages like number of dropped samples or timeout.

Please share the output of the above command.

This part does look like a bad board:

I recommend making sure that the SBX is properly plugged in (tighten the screws, but not too much). Then, you can use usrp_burn_db_eeprom to communicate with the dboard EEPROM. If that works, but the dboard doesn't come up as expected, you might be able to write the PID 0x0083 to the EEPROM and cross your fingers.

Other than that, I'm afraid your slot-B SBX might be busted. Not much else we can do from here -- closing this.

Hi; Please i need to know how to connect USRP X310 to my computer and configure it
