Hello,
I am using N310 to observe its received signal in its four channels. I
observed some unexpected DC offset and harmonics as shown in the
attached figure. It happened only at channels RF0 & RF2; the signal
from channels RF1 & RF3 looks normal. I disconnected the antennas but
the DC and harmonics are still there. And they would not change if I
change the center frequency, sampling rate, or RF gain.
The GNU RADIO and UHD versions are below:
[INFO] [UHD] linux; GNU C++ version 7.5.0; Boost_106501;
UHD_3.15.0.HEAD-0-gaea0e2de
I also attached my python script code in case it would be useful for
you to identify the problem.
Any suggestions? Thank you in advance!
Hua

Also, could you try explicitly specifying a subdev-spec of:
