Yes for either .., or.. but if we want to capture both up- and downlink at the same time, there has to be a setup of 2 USRP2s, am I wrong? With the USRP1 it should, due to the 2 RX slots, be possible to capture both directions.. I would really appreciate a cheaper variant like the one called SSRP.. students as I am, do not have much money.. (and there are many of us out there who would like to join the active development but cannot afford the hardware)
