Why does the config_mimo(MC_WE_SYNC_TO_SMA) always return true, even when there is no reference signal connected to the SMA connector?
>From what I understand, the sync_to_pps() feature works as follows: when the next rising edge of the PPS is encountered, the timestamps are set to zero. But the streaming is started before this, so that you have to manually deduce from the timestamps when the PPS occurs. Is this correct? If so, I think there is one nasty special case, that occurs with a 1/2^32 probability, where you would have to store 1 s of data to be sure that the PPS leading edge has in fact (by accident) occurred exactly at the same time as the 32-bit sample counter has flipped from 2^32 -1 to 0. This could be avoided, if the sample counter is set to >0 and <2^32-10^8 - 1 initially. But anyway, I'm not that worried about this. The possibility of such an event is a thousand times less likely than winning in the lottery. juha _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
