Hi all,
We have a X310 SDR with release version 3.14.1.1 of UHD. We are obtaining
IQ samples from 4 channels.
My question is, X310 includes Automatic Gain Control in samples
depending on signal power? I say that because in the datasheet I couldn't
find any information about that but I observed
Okay, great...
You might want to try increasing the log level. Export
UHD_LOG_CONSOLE_LEVEL=trace or debug and try to make sure the correct xml
file is getting applied to the block correctly.
There's also something like a "--tree" parameter in the uhd_usrp_probe so
try running the probe with the
Also, when I compiled from the OOT directory for ARM, I used this command,
which I pieced together from the RFNoC build guide, and the release-4 guide
for cross-compiling gr-ettus.
cmake
-DCMAKE_TOOLCHAIN_FILE=~/rfnoc/src/gnuradio/cmake/Toolchains/oe-sdk_cross.cmake
-DCMAKE_INSTALL_PREFIX=/usr
Greetings EJ,
So, from the tutorial, they have you edit the gain.xml file, and this is
what I have for it.

We are transmitting samples in bursts of 15360 samples(1ms @ 15.36Msamples/s).
When the magnitudes of the transmitted samples are mostly larger than 1.0, the
received signal, especially the beginning is distorted.
My assumptions is that this distortion happens on the transmitter side. Is this
Hi Michael,
I am experiencing lots of underflows when I use benchmark_rate example app.
Following is the configuration:
Host processor : Intel® Xeon® Processor D-1500 System on Chip (SoC)
Host OS: Centos 7
UHD: release_003_010_001_000
SDR HW: X300 with UBX-160 (Calibration done as
I have successfully built an RFNoC image with a DDC, Window and FFT block using
the recipe mentioned. Also I have been able to connect the blocks using the UHD
library in a C++ program, and I am receiving FFT output to my program. However,
I am still only able to achieve an FFT size of max. 512
