Hi,

I have a couple of X310 each of them has UBX+SBX cards. The devices are synchronized by external 10MHz + PPS signal. But in my test I see random phase delay between all channels that varies between test runs. The test creates multi usrp device, sets up time and tunes to the same frequency using timed command, then it captures some buffers. The same external signal is supplied to all antenna ports. Is it expected to have random delay between channels? Is there any way to have constant phase delay from run to run?

thanks,
Dmitry
