If you're not a member of the usrp-users mailing list you should join that so you can see the responses. It looks like you have BasicRX and BasicTX daugtherboards installed, is that correct? Those daughterboards expose the I and Q channels independently to SMA connectors. You can read about how to use them in different configurations on this page in the manual. http://files.ettus.com/manual/page_dboards.html#dboards_basicrx Regards, Derek On Thu, Aug 2, 2018 at 8:32 PM, Ayaz Mahmud <ayazmah...@hotmail.com<mailto:ayazmah...@hotmail.com>> wrote: Hi, In addition, I have done the following troubleshooting steps as mentioned in the page: Fan spin (checked) Front Panel LEDs (D & F always ON), C (On while Receiving) Voltages : J105 (2.5v), J104 (3.3c), J107(1.2v) – all OK Did not found any other LED on motherboard ON except D202 Thanks, Ayaz From: Ayaz Mahmud<mailto:ayazmah...@hotmail.com> Sent: Thursday, August 2, 2018 11:44 AM To: discuss-gnura...@gnu.org<mailto:discuss-gnura...@gnu.org> Subject: [Discuss-gnuradio] USRP N200 issues and fault troubleshooting Hello, 1. “uhd_usrp_probe” (attached) gives the attached output, where I see the Antennas & Sensors field are showing blank. Is this normal (N200) ? Because for other devices I am using like B210 it shows the Antenna names. 1. For testing purpose if I run the below command which gives error in antenna naming. But if I skip the (-A RX2) it runs without any error. “uhd_fft –args “addr=192.168.10.2” -A RX2 -s 10e6 -g 10 -f 100e6” Traceback (most recent call last): File "/usr/local/bin/uhd_fft", line 448, in <module> main() File "/usr/local/bin/uhd_fft", line 431, in main tb = uhd_fft(args) File "/usr/local/bin/uhd_fft", line 128, in __init__ self.setup_usrp(uhd.usrp_source, args) File "/usr/local/lib/python2.7/dist-packages/gnuradio/uhd/uhd_app.py", line 156, in setup_usrp self.vprint("[ERROR] {} is not a valid antenna name for this USRP device!".format(ant)) NameError: global name 'ant' is not defined 1. To make sure if the receiver is working or not, I have designed a flow graph for fm radio. I can get a clear signal in my B210 device, but at the same configuration it just noise in N200. What should be my next step to troubleshoot ? Or how can I be sure that it is a faulty device?
