[USRP-users] Phantom USRP X300 Detections from uhd::device::find

2017-11-07 Thread Perelman, Nathan via USRP-users
My application runs uhd::device::find() (with no arguments) every 5 seconds or so to detect when a user has plugged in a new USRP. Rarely (on the order of once or twice per day), this reports detecting an X300 with an IP address matching the IP address of the computer the application is running on,

[USRP-users] USRP B210 time errors with high master clock rate

2017-10-25 Thread Perelman, Nathan via USRP-users
I've seen some odd behavior with timestamps for samples from the B210 being off by large fractions of a second from what I expected when setting the time to GPS time. I wrote a program (see attached) that uses get_time_last_pps() to attempt to validate that the time is being set correctly. I discov

[USRP-users] Determining if an X300 is connected via 10 GigE or 1 GigE

2017-07-27 Thread Perelman, Nathan via USRP-users
I had been looking at /mboards/0/link_max_rate to determine if an X300 was connected via 10 GigE or 1 GigE. However it seems like sometime between when that was implemented for the X300 ( https://github.com/EttusResearch/uhd/commit/6a72c16ee909af95b6965f26fb588a29 485ef414 ) and now ( https://githu
