Re: [USRP-users] Sending multiple contiguous transmit requests

2020-06-03 Thread Richard Joseph Muri via USRP-users
For posterity here is a solution I arrived at. I was ignoring the md.start_of_burst and md.end_of_burst fields. In order to send many contiguous transmit requests without receiving erroneous late errors, send the first transmit request in a chain with md.has_time_spec true, md.start_of_burst

[USRP-users] Sending multiple contiguous transmit requests

Hello, I've been having an issue with the USRP where I've found if I have a continuous waveform segmented over multiple packets, it is difficult to transmit it on the USRP. The scenario is as follows: I am using a USRP x310 with UHD version: [INFO] [UHD] linux; GNU C++ version 4.8.5 201506

2020-01-28 Thread Richard Joseph Muri via USRP-users
Hello, I have an application that schedules transmissions/receives on a short time scale (order of tens of microseconds). I'm attempting to gauge the feasibility of using a x310 with UBX-160 daughterboards and 10Gb ethernet for the application. I wrote a quick test to see approximately how l

[USRP-users] X310 scheduled issue_stream_cmd()

2020-01-14 Thread Richard Joseph Muri via USRP-users
Hello, I'm using an X310 with a number of scheduled receives. I suspect there is a FIFO on the USRP that holds the stream_cmd_t until it is time to collect the requested samples. I have not been able to find documentation about the size of this FIFO. Could anybody point me in the proper direct
