Ad9371 Frequency change and Noise Floor

hi,

i am totally new in this field and new some help.
i have 3 question about the ad9371 transceiver ic.
i. How to change the central Frequency in run time and how much time it will take to shift?
ii. what is the noise floor value at RX end at -80 dB, as this ic has sensitivity of -80dB.
iii. How can i reduce the bandwidth (RX side only) without slow down the IQ data rate. (in form at analog.com i found that it may be not possible) kindly explain.
i am new to this domain and still learning we are working with a AD9371 no-OS application currently.
thanks in advance

regards

  • thank u sir for reply.

    sir is it possible to re-run this code (present in the ARM processor to change central frequency and run calibrations) from the PL. i mean we are doing most of our work in PL side and PS is only configuring the device. sir what is the best approach for that purpose.

    thanks & regards

  • Good day sir,

    sir i wanna to know if it is possible with AD9371 putting TX LO at fix frequency and then hop to a near by frequency within the TX bandwidth (TX has 100 MHz bandwidth) without changing the central frequency of Tx.

    regards

  • What do you mean by hoping to the nearest frequency without changing the LO? If you set the LO to a fixed frequency, then you can send your input data anywhere within LO+/-50MHz.

  • i want to say that, i have set the central frequency at 2.4 GHz and now i want to hop (jump) above and below this frequency about 8 MHz, i want to control this hops (more than 100k hops per seconds) above and below my central frequency and is it possible to do that with AD9371?

    should i change the central frequency for that?

    is it even possible with this device?

    can you suggest any possible solution how to do that with ad9371 if possible

    thanks
