As I understand it, the AD9361 chooses whatever baseband it deems fit for
the given receiver being implemented. How can we know what baseband the
AD9361 has decided to choose?

Thanks everyone for trying to sort this out!
Robbin - as you stated yourself, spliiters and channel coupling should have
minor effect, especially in our case where the wavelength is larger than
the whole system.
Ian - I am actually using a proper external signal generator. No loopbacks.

Is it feasible for your application to just have one streamer for all your
X300s, but just stream 0s on the channels you arent using? I have also
found that re-configuring streamers is messy.

Hi Jeff,
Thanks for your response, but you understood me completely wrong.
Of course I have set the RF freq in the source block. Furthermore, I
have fully analized the signal from both chanels, and it appears
crystal clear in all the sinks throughout the flow graph (e.g., a pure

Hi all,
We are building an application using multiple X300s under Ubuntu 16.04,
using UHD 3.10.3.0
The application needs to transmit data to different X300s, depending on the
status of the application.
So, each time we need to transmit data to a different set of X300s, we
destroy and re-create a

thank you for noticing this. We will take care of this shortly.

Theoretically, in frequency domain, the spectrum for SQUARE wave should be a
SINC and for the spectrum of RAMP wave should be decreasing with every odd
harmonics. A question that I want to ask is, will I get to see these frequency
