AD9371 Receive QEC response time

Hi, I would be grateful for some help with some questions about the Rx QEC function please:

(1) How long does the initial Rx QEC calibration take?

(2) How long the real-time QEC function takes to achieve the specification of -75dBc for image rejection when the frequency is changed?

(3) When QEC is turned on from being off, how long then does it take to reach specification?

(4) It looks as if there are some registers displaying the status of the Rx QEC, is it possible to tell when the QEC has reached specification of -75dB rejection and when it is not working for some reason?

Many thanks.
