Dear
I am using an X310 with WBX-120 and TwinRX daughterboards. The transmission seems to have a lot of carrier leakage (when sending a stream of 0's, there is still a frequency spike at the carrier frequency at -50dBm). I found out about calibration methods, which are supported by the TX board (WBX-120). https://files.ettus.com/manual/page_calibration.html
When running the uhd_usrp_probe command, I can see the board gives me the following info:
TX Frontend: 0
| | | Name: WBX-120 TX+GDB
| | | Antennas: TX/RX, CAL
| | | Sensors: lo_locked
| | | Freq range: 25.000 to 2200.000 MHz
| | | Gain range PGA0: 0.0 to 31.0 step 1.0 dB
| | | Bandwidth range: 120000000.0 to 120000000.0 step 0.0 Hz
| | | Connection Type: IQ
| | | Uses LO offset: No
However, when running uhd_cal_tx_iq_balance or uhd_cal_tx_dc_offset it gives me the following error:
Running calibration for WBX-120 TX+GDB
Daughterboard serial: [censored]
Error: This board does not have the CAL antenna option, cannot self-calibrate.
Any ideas?
