So everything worked fine except I got the following warning:
UHD Warning:
Mixing real and quadrature rx subdevices is not supported.
The Q input to the real source(s) will be non-zero.
Which is probably due to my wish to use WBX with IQ and only one channel
from LFTX. Is there any way to
Everything is OK, I have just put "B:A A:0" in the subdevice field.

I did following: I made simple flow graph and used USRP source first with
two channels and LFTX mboard. But the follwong error occurs:
File "/home/savi_ne/work/gnuradio/GRC/top_block.py", line 105, in __init__

File "/usr/local/lib64/
Thank you Marcus again,
I changed device address, in both places, but the same problem appears. I
see that it loads now 4rx image, but the problem remains.
self.uhd_usrp_source_1 = uhd.usrp_source(
device_addr="fpga=usrp1_fpga_4rx.rbf",
stream_args=uhd.stream_args(

I see, but still don't get where this change should be made.
And also, more important, i I have standard configuration with 2 DDCs and 2
DUCs, then it should work like that, cause I need only 2 DDCs if I am not
wrong.

Hi,
Is there an example where two usrp sources are used to sample from two
daughtercards simultaneously? Or is this even possible?
Best Regards,
