[USRP-users] Overflow using Keep One In N block

Hello, I am currently working with the X410(X4_400 image) using other the 1Gbe ethernet only(for now) and an image that uses the following RFNOC graph Active connections: \* 0/Radio#0:0-->0/KeepOneInN#0:0 \* 0/KeepOneInN#0:0-->RxStreamer#0:0. Regardless of any value of N I use(even when the m

[USRP-users] A2D bit depth vs IQ

Hello peeps, Just wondering if anyone could point me to where the mapping between bits and IQ takes place. Curious if the strategy is the same across platforms even though bit depth varies (b205: 12 bits, X310: 15 bits, N310: 16 bits, X410: 12 bits...). The above info in general would be usefu

[USRP-users] Re: N320 SFP MAC issue

Thanks for the ideas Marcus. I did check ifconfig/ethtool, and my desktop debugging setup shows no RX errors on the corresponding 10Gbps interface. I'll keep monitoring just in case it's a matter of time until something shows up. I've been testing for a day or so now . . . I forgot to mention i

[USRP-users] TwinRX phase synchronisation using different versions of UHD

I am using code utilizing the UHD library to capture samples from a X310 with 2 TwinRX daughterboards. The sample rate is set to 25MSps. This is to characterize the system to ultimately use it in for phase interferometry direction finding similar to AN-244 (https://kb.ettus.com/Direction_Findin

Thank you Marcus, that is helpful. I have restricted my testing to just an N320, and only freq changes for now.  I have run across something else that is odd though (but has major ramifications for my blocks).  Most of the time there are no drops and everything is fine, but here is an example o

[USRP-users] Using X310 with two hosts

Hello everybody, I was wondering if an usrp x310 with two daughter boards can be used simultaneously with two host computers using the two SFP interfaces. The daughter boards would be the UBX160 and I need the usrp to run Openairinterface simulations. Thanks in advance, Andrea de Jesus Torres _
