I actually synchronize multiple USRPs with unaligned 10MHz and pps. Sometimes two USRPs are offset one clock cycle (10ns) but that is OK for my application. Of course, I need also to consider that one pps interval will not be exactly 100e6 clock cyckles BR/ Per _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
