Hi.
We have developed a project using the USRP 2945 and UHD libraries to estimate a
signal's direction of arrival.
In this project, the four channels of the USRP 2945 are connected through a
power splitter to a function generator, and the local oscillators in the back
are connected following
Hi Marcus,
Thank you for your mail.
I done based on your information as follows.

Hi,
I have a few questions regarding tx_waveforms script.
I'm using an USRP B200mini.
How can I delete (or reduce) the DC component when using tx_waveform?
When I set --freq=f0, specifying --lo_offset=(df0), how do I remove (or
reduce) the mirrored replica at (f0+2*f0) that is generated? Do you
Hi Carlo,
Your questions are about 2 calibrations: DC offset (affects DC component)
and I/Q gain/phase calibration (affects mirrored spectra). My
understanding is that the B200 calibrations are handled automatically such
that there is nothing to do from "tx_waveforms" or even from direct UHD API
c
Try reducing the baseband signal magnitude and RF gain—does that reduce the
unwanted harmonic content?
What offset value are you using? I typically use a value that is a bit more
than half my application bandwidth.
Some Amount of unwanted mixing and distortion products are *inevitable* with

Hi Dario,
UHD 4.0 requires DPDK 18.11, but Ubuntu 20.04.1 packages version 19.11. See
the UHD manual for how to build version 18.11:
