set_freq would not be a good measure, since it takes a while to configure the daughterboard. find() isn't great either, since it waits 10ms to ensure that it's gathered all responses to it's broadcast. set_rx_decim should give a reasonable measurement, as long as you're not streaming data.

Hi, Wouldn't one be able to use for instance "set_freq()" or find() as a messure? Although there might be some overhead, you will receive an "ok I have set the freq"/"Ok here I am"- packet from the usrp2. Although one could think of more elaborate schemes involving a special OP_CODE (usrp2_et

Hi, If USRP2 can respond to PING and reply back, then one should be able to measure the delay. Regards, Firas ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

I foud this wery usefull: http://www.gnuradio.org/trac/wiki/UsrpFAQ/Latency Is there similar calculations about the latency of the USRP2? If there is not, could someone please do those calculations? -- - Pauli Rikula ___ Discuss-gnuradio mailing lis
