Physical signal withe CC2520 development kit

Other Parts Discussed in Thread: CC2520

Hi,

I'm working in a project that uses the CC2520 development kit, my mission is to access and retrieve the physical signal in the receiver's side.
I'm starting in ZigBee, and this operation is so difficult for me. If you have any ideas where to start, or if anyone has already done this manipulation.
Thank you for helping me.

    By  "retrieving the physical signal" you refer to acquiring the waveform of the radio signal downconverted to baseband?

    I think it is not possible for the CC2520 since the radio and baseband signals are internally processed and demodulated, and therefore are not accesible.

    hi,

    I know that this operation seems impossible, but I believe that we can recovered the received signal' samples before the decision is taken.
    On the CC2520 block diagram, the block RF_core communicate on the Bus Controller. So if we can access  to the demodulator which founded in this block, we can recover some potentials informations.

    If anyone have some ideas...

    Thanks
