Note: I missed the USRP2 part in the subject on my first reply... On the USRP1, they do if you want the 4 Rx chains. The standard FPGA image for the USRP1 contains 2 Rx and 2 Tx chains, so (if he was using the USRP1 (which he isn't)) he could do two Rx with the standard image. > Is there such an FPGA build for the USRP2? (I ask > because the multi-antenna scripts don't seem to represent that) Right now the standard USRP2 FPGA image contains a single Rx and single Tx chain. Once the conversion to VRT is done (and we overhaul the API so that you can control a wide variety of things such as multiple Tx and Rx chains), this will be possible on the USRP2. In the meanwhile, folks are on their own ;-) Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
