Hello,I have a problem when I was testing the sensitivity of cc1121,the frequecy of my cc1121 module is 469.995MHz,if the frequecy of generator is set to 469.995MHz,the sensitivity is -116dBm(@BER<0.1%), and if the frequecy of generator is set to 469.999 or 469.991MHz(Offset=±4KHz),the sensitivity is become -113dBm(@BER<0.1%), but this problem does not occur on the cc1100e moudle, why?
the other register of cc1121 is: symbol rate = 2.4Kbps,deviation=20KHz,RX filter BW=50khz,synchronous serial mode, the demodulation signal return the generator(R&S SMJ100A) through GPIO2 pin;
and the orther question, how to read the following figure?
