ADRV9002_TES_TDDMODE_RFLOOPback

Hello.

I have one question. Please tell me.

I use TES. I have confirmed the operation in TDD mode.

Is it possible to receive and display the waveform transmitted by this operation with RF loopback?

I have confirmed that this is possible with FDD MODE.

I don't use an external PA, I just connect TX1 and RX2 with a coaxial cable.

Best Regards.

    Hello baggio,

    I'm afraid with TDD applications there is a strict limitation on only transmitting or receiving at any given time, meaning a loopback from either Tx to either Rx won't yield any results for you.

    To monitor your Tx spectrum in TDD mode your best option is to use an external spectrum analyzer.

    I hope this helps!

    Best Regards,
    Oisín.
