This question is directed to Josh Blum, but if anyone can comment,
it would be welcome: I tried the calibration apps this evening on a B100 and a Rev3 N210. See http://files.ettus.com/uhd_docs/manual/html/calibration.html The B100 worked like a champ and all three calibration procedures completed. Unfortunately, when I tried the procedure on my N210, it failed, reporting that the LO failed to lock in a timely manner. Output pasted below: address@hidden:~$ sudo /usr/local/bin/uhd_cal_rx_iq_balance --verbose linux; GNU C++ version 4.5.2; Boost_104200; UHD_003.004.000-7dc76db Creating the usrp device with: ... -- Opening a USRP2/N-Series device... -- Current recv frame size: 1472 bytes -- Current send frame size: 1472 bytes Error: timed out waiting for TX and/or RX LO to lock The N210 does work in flowgraphs and other applications and I have verified that the lo locks in a flowgraph by probing the get_dboard_sensor function. I have a WBX in both units. I am running the very latest master of both GR and UHD. Both units have the latest FPGA code and firmware. |
