Hi to all,

I want to work with a wideband signal. The bandwidth will be very high
(I will push the limits). I have X310, UBX-160 and PCI-Express
Connectivity Kit (PCIe – Desktop)
https://www.ettus.com/product/details/PCIE-KIT. There is Intel 8
series/C220 chipset in my desktop computer.

I searched the Ettus' website and find this
https://files.ettus.com/manual/page_ni_rio_kernel.html.

** In Windows Labview 2015
When I run NI USRP-Configuration Utility, I get:
Device ID: RIO0
Connection: PCIe
Type/Revision: X310/UBX-160 v1/rev8

Then I run an example program and get the error:
USRP RIO: Hardware is too new for this version of the Configuration
Instrument Design Library.

Anyway, I already know that Labview does not support UBX card. So I
left working on Labview. Actually, I do not know much about Labview.

**In Linux
I installed the given NI USRPRIO kernels. When I write the
"uhd_usrp_probe", UHD sees the device.
...
-- Connecting to niusrpriopc at localhost:5444...
...

So it is working. But then, how can I use USRP in Linux? I actually
want to work with GNURadio. Is it possible to work on GNURadio with
PCIe connection? Or do I have to write in Python? I did not see any
example of usage in Linux on the internet.

In short, please tell me how can I record I/Q data of a wideband
signal with PCIe connection in Linux, prefferably by GNURadio?

Best regards,
Ali

If you just want to record, you can use the 'uhd_rx_cfile' utility that is
part of Gnu Radio.

You can also use 'rx_samples_to_file' that is part of UHD.

Be aware that making high-bandwidth recording work requires both a FAST
computer, and a suitable SSD-based disk subsystem.

In either case, you'd just specify  "resource=RIO0"  in the device
arguments when using the UHD utilities, or Gnu Radio programs.
