Hi all,
I’m working on a multi-channel, phase-coherent transceiver platform using
the N310 and RFNoC Replay block (UHD4.6). It has been tested successfully
for 4TX and 4RX individually.
However, I’m facing challenges getting 4TX and 4RX to work simultaneously.
Attempts to configure:

Hi,
By the way, there's a note in AN-823 indicating the required Vivado edition
for the USRP device.

*NOTE:*
- The edition of Xilinx Vivado that is required will depend on which
USRP device is being used.

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

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
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'
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
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

Hi Marcus
Sorry for the confusion, the problem is no signal at all, and the
application just hang without any message.
Thanks

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,
