Hi Nikos,

Thanks for replying me. Now, I understood the reason for that error and corrected it and the execution goes well.

Thank you,

Hi,

You can have only 1 RX and 1 TX channel in a N210. You are asking for 2 RX channels in your flow. Runtime complains that he can access only 1 channel (Rx0).

HTH,

Hi All,

I am using GNU Radio Companion 3.7.5 and USRP N210.

When I implemented a simple flow graph of SIMO system with two channels using USRP source block ( attached grc flow graph snapshot for reference),

I am getting following error:

Traceback (most recent call last):
  File "/home/student/SUGAN/ONE_TWO.py", line 130, in <module>
    tb = ONE_TWO()
  File "/home/student/SUGAN/ONE_TWO.py", line 72, in __init__
    channels=range(2),

    return _uhd_swig.usrp_source_make(*args)
RuntimeError: LookupError: IndexError: multi_usrp: RX channel 1 out of range for configured RX frontends

Can anyone help me to fix this error?

Thanks in advance
