Hi, The X300/X310 supports three Sampling Rates: 120MHz, 184.32MHz, and 200MHz. Your rate was most likely coerced to the most common rate of 200M. The FPGA then performs decimation and interpolation such that the host doesn't have to stream all that bandwidth (nor can it in most cases). The streaming rate called out in your screen shots is 10.0Msps.
Does that answer your question? -Daniel On Fri, Mar 2, 2018 at 7:57 AM, Андрей 1 via USRP-users < usrp-users@lists.ettus.com> wrote: > Hello > > When I open device with uhd_usrp_make in the terminal I see a message > "invalid sample rate 100 MHz actual rate is 200 MHz".The same message I see > when running application from uhd samples folder. > If I set sample rate 200 MHz and then read them from device I got 100 MHz. > > What does this mean and what is the maximum clock of the X300 in single > and multichannel mode? > > See png for detail. > > Thank you > > _______________________________________________ > USRP-users mailing list > USRP-users@lists.ettus.com > http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com > > -- Daniel Jepson Digital Hardware Engineer National Instruments O: +1.512.683.6163 daniel.jep...@ni.com
