    RF spike in BCM20713

    user_85677719

      Dear community,

      I use a BCM20713 in a product. During bluetooth test performed in a shielded chamber with a Bluetooth protocol analyzer I found that in more or less 20% of products there are a spike in the BT modulation in time domain. This noise makes that you are unable to perform the measurement properly. In particular the instrument says me that the packet is incorrect.

      In detail, I'm try to performs a transmit test from the DUT to the instrument using EDR BT technology.

      the spike seems happens at the transmitter turn-on.

       

      In annex a snapshot of that.

      Could you please let me know what can generate this behaviour and how I can try to solve it?

       

      thanks a lot,

      BR,

      Giordano
