Hello,
Thanks for your suggestion. I tried to replace the second DSP Core by a
simple counter so that i should receive something on the second channel.
Then instatiated a UHD source block in GRC, added a second channel (Num
Channels = 2) to the UHD Source block and configured it the same way as
the other channel. Then I tried to run the graph but it keeps telling me
that the configuration of the the second channel is wrong (e.g:
uhd_usrp_source_0.set_center_freq(10000000, 1) leads to
vector::_M_range_check ... Maybe I'm just using wrong parameters for the
second channel?)
By the way: I'm using a WBX board to get the I/Q Samples. Are there
maybe any other parameters for the USRP board necessary (subdev specs?)
to get this additional samples?
Thank you,
Eral

You may want to replace the second DSP in the top level verilog with
your own module. On the host side, just configure the uhd source block
for two channels.
