[USRP-users] Is it able to use RFNoC Replay Block on the receiver chain?

Hi USRP users, In the example "rfnoc_replay_samples_from_file.cpp", we connect SEP and NoC blocks as follows: (Tx_streamer)=>[Replay#0:0]=>[DUC#0:0]=>[Radio#0:0]. It first sends samples from host and records them to the on board memory, then replays them from the on board memory continuously. We'

Re: [USRP-users] N310 Multi Device Configuration

Hi, Neharika and All, I met some problems on controlling 2 N310s too. But first of all, the argument "second_addr" indicates the IP addr. of the second SFP+ port on that device, and is set in the case of dual 10G streaming. I think the first way you wrote is the right way to access the 2 N310s, e

Re: [USRP-users] synchronizing multiple USRP N310

Hi USRP Users I tried to synchronize 2 N310s throught the external PPS and reference clock, and tested by the application below. *tx_waveforms.exe --args "addr0=192.168.30.3,addr1=192.168.40.3,clock_source=external,time_source=external,master_clock_rate=122.88e6" --rate 30.72e6 --freq 3.5e9 --wav

[USRP-users] Probe N310 on Windows OS

Hi USRP Users I got the new N310, and followed the online Getting Started Guides step by step, and I'm able to run the rx_ascii_art_dft and some example programs on Ubuntu. However, while I tried it on Windows OS, I can ping the address (192.168.10.2) and find it using uhd_find_devices.exe, bu

[USRP-users] X310 REF LED is blinking

Dear all The LED of REF on the front panel of one of my X310 is blinking instead of constantly lighting up while working, that is, the reference clock is not able to be locked with other x310s (4x4 MIMO system). I've checked the reference clock source is constantly output, and other X310s works f

[USRP-users] PPS and REF out form a X310 and leakage problem

Hi all I’d like to build up 8X8 MIMO system using 4 USRP X310. To synchronize time&freq. between all of them, I used to use a function generator to feed both 1 PPS and 10 MHz reference clock to them. Today, I got an Octoclock which I thought it is able to provide both synchronization signal, b
