[USRP-users] Weatherproof Enclosure for N310

Hi, I am considering to get an IP67-rated enclosure for N310 for outdoor deployment. I wonder if I do everything correctly, could I improve the environmental conditions of N310 to the same level of E313 (which is an E310 carefully enclosed by an IP67-rated case)? USRP E313 (

[USRP-users] SFP Transceivers for N310 1/10Gbps Fiber Ethernet

Hi, I am working on a project where several N310s are connected to a fiber-Ethernet switch. The fibers are of single mode with length from 1km to 10km. My problem is selecting the right SFP transceivers. Currently, I used the official SFP to RJ45 converter (come from Ettus with N310) followed by

Re: [USRP-users] TwinRx Channel Alignment

Hi Derek, I have two questions about the rx timed samples example, 1. is there python version for timed command? 2. Is the time stamp from the clock on USRP or on the host? Thanks Zhongyuan Zhao PhD Candidate, Department of Computer Science & Engineering, University of Nebraska-Lincoln Office

Re: [USRP-users] TwinRx Channel Alignment

Hi Marcus and Derek, Thank you for the reply. The RFNoC and synchronization are very helpful. I have an additional question regarding to the timestaming in GNURadio. In the VITA and CHDR format of RFNoC, there are timestamp and stream ID, what could I do to keep the timestamp and stream ID via a

Re: [USRP-users] TwinRx Channel Alignment

Hi Derek, If USRPs A & B clocked by an Octoclock, are connected to the same host, I want calibrate the counter values from USRPs A and B. How can I do it? Is this function supported by UHD? If not, could I update the counter values in the FPGA Radio blocks? or I can only keep an calibration table

Re: [USRP-users] [Discuss-gnuradio] Specify Versions of UHD and GRC for PyBombs

Hi Marcus, Thank you for the detailed explanation. I think this is very helpful. The reason I need a specific version of UHD is to work with a remote N310. It seems that to work with a N310, the versions of Ubuntu (sdimg), FPGA image, and UHD on the host computer must all match. However, since my
