    Hello,

    I need to know what is the ADC resolution (8, 10, 12, 14 bits) from SA44B.
    Thank you.

    BR,

    It’s actually a sigma delta 24 bit ADC, digitally converted to 16-bit I&Q.

    Are you able to go into any more detail about that process Justin?
    Is the ADC actually running at 24bits or something less?
    What is inside the ‘digital converter’ process?

    Thanks,
    Roger

    It is an AD9864. We run it at 10.7 MHz, or bypass the mixer and run it at 2.9 MHz in “hung mixer” mode.
