Hello ,
I'm using the EVK of the CC2511 at 500kb/s and I measure the BER compare to the attenutation ( this is doing by using a spectrum meter + some attenuator ).see below the picture :
when the attenuation is above -40 ( -30, -20) the BER increase rapidly. This can happen when two products are closed.
My question is :
How I can use the AGC register to ajuste the LNA compare to the input power . i.e when the input power is high decrease the LNA and when the input power is low ingrease the LNA gain .
Is it possible that the CC2511 adjust by itself the LNA gain ?
I hope I'm clear in my question , it is not easy to explain.
