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 On 05/09/2011 09:55, Josh Blum wrote:
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.
