Frequency Hopping in ADRV9002

Hi,

    We are using ADRV9002 RF Transceiver for our applications. Is it possible to achieve the loopback operation in Frequency Hopping mode in ADRV9002, if it so please provide the configurations modes that need to be set.

Thanks

  • Hi VijayKS,

    I'll take a look into this and report back to you. My suspicion is that FH cannot be used with a loopback as FH is typically used with TDD, which precludes the separation of Tx and Rx on a time basis.

    I'll return when I've investigated further!

    Best Regards,

  • Hi,

       Thanks for your response. We achieved Frequency Hopping in Tx channel of ADRV9002, but couldn't achieve Frequency hopping in Rx channel. Can you please provide me configurations or modes that need to set to achieve hopping in Rx channel.

    Thanks,

    VijayKS

  • Hi VijayKS,

    Frequency Hopping shouldn't discriminate between Tx and Rx channels as it acts on the channel LO. Controlling Hopping times and channel assignment is best achieved in the Auto TDD tab. In the following images I setup a simple LTE demonstration. I use two frequency hopping tables provided with TES in the Examples folder. I then enable Auto TDD and use the corresponding Auto TDD timings. There are a set of extra signals provided with this table that are used to trigger external equipment captures and provide a means for the user to keep track of the frame as it cycles.

    Do let me know if this info helps you get further in your development!

    Best Regards,
    Oisín.

  • Hi Oisin,

         Thanks for your response.
