[USRP-users] GPS time incorrect on E310 until almanac downloads

2017-10-05 Thread Sirkin, Joshua F. via USRP-users
It appears that the GPS time defaults to 15 leap seconds at bootup until the almanac downloads but it should be at 18 leap seconds. This causes a problem on startup. Is there anyway to force the E310 to store the offset value and use that at next bootup? Is there a flag that I can check to

Hi, we have a Dell server running Centos 7.4 with a B210 plugged into a USB 3 port on the back. Everything works great when we plug in the B210 after boot, but if the B210 is plugged in before boot the device is not recognized and we get these errors in dmesg: Usb 3-8: device descriptor

I have experienced the same issue on a couple of my newer E310s. I have not been able to confirm yet, mainly because it is hard to reproduce, but from what I can tell, most of the times I have seen it are when an E310 has been powered off for a longer period of time. Not quite sure how to

[USRP-users] Using GPSDO with gps lock

2019-02-23 Thread Sirkin, Joshua F. via USRP-users
I had a question about the TCXO GPSDO module for the B200/B210. I am interested in using it without a gps lock as a better clock than the tcxo that is internal to the bare board. I am only interested in frequency stability, not time of day. If I did use it in this way, I had a few
