I am trying to create a simple gnuradio-companion flowgraph that uses a Multi-USRP block to record all 4 channels from an X410 into data files on my hard drive. I am struggling with the subdev specifications, and keep getting syntax errors, and sometime receiver channel number errors. I'm clearly not understanding how the X410 differs from the X310, which I have used a lot in the past without any problems.
Does anybody have an example grc file that records all 4 channels from an X410? Or could someone just tell me what the subdev specs should be in my Multi-USRP block? It's my understanding that the X410 has 2 ZBX daughter boards, and each ZBX daughter board has 2 channels. I thought it would be easy to do this, but I can't seem to get it working.
