Has anyone had any problem with setting up MIMO with USRP2? I am trying to replicate an N210 MIMO setup that I had a while ago and just replaced N210 with 2 USRP2s. They are connected with a MIMO cable while one of them is connected with an ethernet cable to the host. Both devices are set with 2 different IP addresses and I can ping both of them in the MIMO setup. But when I feed both USRP2s with a sine wave (coming from one source), my scope sink only shows the signal from one USRP2 (the slave one) and the other channel shows just noise. Is there any limitation for USRP2s in MIMO configuration?
