Hi,
I have a setup of several X310s connected over 10Gbit Ethernet, and synced with
an Octoclock. I'm generating signals on a PC, and streaming the signals to the
X310s to get coherent waveforms. For now I'm generating sinusoids where the
phase of each channel slowly varies with time at differe
Thanks Rob.
I have registered the issue in https://github.com/EttusResearch/uhd/issues/367
and nagged their support email.

I ran benchmark_rate --args=="addr0=192.168.10.2,addr1=192.168.110.2" --tx_rate
5e6 --tx_channels="0,2"
And I observed the same issue I described earlier – mostly that ether channels
0,1 or channels 2,3, or very rarely channels 0,2 get enabled.
When I add “skip_dram=1” to args, the channe
Thanks for pointing that out Rob.
I have created a std::vector enabled_channels = {0, 2}. I also changed
so that those channel numbers (0 and 2) are used to tune the radios, adjust
gain and check for locked LO. Code is attached.
Now I still have similar issues and I observe 3 cases:

I have attached the code for a channel mapping of (0,2) in siggen.cc. I also
include my CMakeLists file.
Program is run without arguments; ./siggen
Attached output_case_1.txt shows the program out
Thanks for that suggestion Rob,
I have tested this now, I now address both devices, I have changed subdev spec
to "A:0 B:0" for both motherboards (lines 35, 36).
Then I tried several values for stream_args.channels:
I tried with stream_args.channels = (0,2). Here I expect signal on A outputs on
Hi,
I have a setup with two USRP X310. Each X310 has two UBX-40 daughterboards for
a total of 4 RX channels and 4 TX channels. Attached is the uhd_usrp_probe
status for the USRP X310s in my setup.
Both X310s are connected to an OctoClock-G, where they get fed 10MHz and 1PPS.
