Hi, I am using a B205 and I'd just like to know what are the
difference filter stages (analog and digital) seen by the signal (both Tx
and Rx), in the AD936x and in the FPGA.
Another way to help me, should be to have a description of the filter that
I can address with the filter.hpp functions : Can

That works fine, but I had to change the uhd version to the last one
(3.15). Just for information,That does not work on 3.11.
Many thanks

I have tried that, but I see 2 issues (but perhaps I'm wrong) :
- I need 25 Mhz of BW so if I want to push the LO outside, I need to have a
sample rate of 50 MHz --> difficult to have Tx / Rx loopback.
- I have tried to set the master clock rate at 60 MHz, the DDC offset at 25
MHz, and a sample rat

Hello, could someone help me where one can find the UHD Cpp file where the
DC offset correction of AD936x is enabled ?
I need to make a Rx --> Tx loop which is independent of the center
frequency of the Rx signal.
Thanks a lot

Ok thanks. The code is really simple and i don't think it can be optimized.
Is there other linux OS i can try ?
Thanks again.

Hello, I have made a c++ code which sends samples in the main function and
receives samples in a thread launched in this main function.
I have read that we can set the real time priority with the
set_thread_priority function.
I have tried to call this function (with parameters (1,true) inside the
m
OK thanks. So you confirm the link between UHD sample rate and AD93xx
sample rate ?

Hello.
We are trying to make a simple RX on TX loopback by changing the FPGA image.
We get it by adding a wire between the DDC output and DUC input, but we are
still limited by the sample rate we specify via UHD.
We have specified the analog bandwidth at 56 MHz, and the master
clock rate at 60 MHz
