Re: sending single tone Am modulated using usrp1+wbx

Ok, I will try with an attenuator, but I suppose I can work too(while I
get
an attenuator) with two antennas setting the proper gain for each one,
but
now I have the next question: Independently if I work with attenuator or
antennas, why the gain affects the spectrum and shape of the received
signal?

Thanks.

Without seeing the details, I can’t comment in detail.

But as you increase the RX gain, more of the weaker components of the
signal start to rise above the noise floor of your configuration, so you
can
see them. As you increase gain further, depending on the strength of
the TX signal, you end up with the amplifier operating in a non-linear
fashion,
thus distorting the signal.
