Hi Marcus, The LLL errors happened in host when it talks to N321.N321 is connected to the host through two 10GigE SFP cables directly; these is no other device in the middle. N321 has one extra RJ45 1GigE cable for management. This cable is connected to a switch; host is also connected to this

FYI - I ended up reading the raw temp values from the E310's /sys file system. I had to estimate the offset value for the Zynq temp sensor, so it might not be accurate. Here's the code I ended up using. It runs on UHD 3.15, but I don't know about UHD 4.x. Rich On Wed, Aug 25, 2021 at 5:06 PM R

Hi, Following up on this, the question I'm trying to answer is: "Can I calibrate the rx power on an N210 + UBX platform?" With the N210, has_rx_power_reference() returns False. Can I conclude f

Thanks for the tip, it helped me find what was ultimately an embarrassing mistake. I’ll post the explanation in case it helps someone new in the future. By default, gnuradio generates a python script with a try/except block in main() that passes on EOF. The correct solution was to replace this b

[USRP-users] Re: E320 how use the E320 as ntp time server using its internal gpsdo as time source

Assuming you have ntp on your device (default img from ettus doesn’t have it), set /etc/ntp.conf to: ``` # GPS Serial data reference server 127.127.28.0 minpoll 4 maxpoll 4 fudge 127.127.28.0 time1 0.0 refid GPS # GPS PPS reference server 127.127.28.1 minpoll 4 maxpoll 4 prefer fudge 127.127.28.

Thanks Marcus, A couple more questions on this: [1] Would it be possible for us to buy a USRP X310 (which supports the reference power API), run uhd_power_cal and then transfer the UBX DB to the N210 and expect calibrated power measurements? Or does the reference power API need to be working on t
