Sorry for not stating the hardware earlier. I am using USRP N210, with
RFX2400 and WBX boards.

Hi Ali,

Of course, since power is proportional to amplitude squared.
Obviously, if you try to drive an DAC with more than it's maximum
amplitude, you will get clipping.
This is a nonlinear thing and has very bad effects on your spectrum, and
that's why you usually avoid it.
Hi Ali,
well, then what's the problem when running the Python file in a terminal?
Usually, this will be something like your audio device being

Given your question, I think you already know the answer. 2MHz is far

you need to be a little more proactive when trying to solve your
problems. As you have showed in other posts, you're able to run programs
from a command line (e.g. cmake), and that's what you should do here.

Hi Abouda,
in GNU Radio, there's no real main loop; I don't really know what you're
trying to do.
The python files GNU Radio generates are executables, you can just run
them in a terminal without GRC :)

That sort of wraps it
Thanks for your reply,
According to you what is the best way to avoid compilation error for E110
to install gnuradio on E110 ? In fact, I did swap memory to extend the RAM
but I still have problems on compilation.

Hi all:
Thank you in advance.

I have read the

self.connect(self, self.chan_filt)#
filter the input channel
Well, clipping *definitively* will occur when you leave the +-1 range;
below that, clipping can happen in the analog part, which the USRP can't
warn you about.
