Hi Albert,
Thanks for your reply.
I should start the AIF2 at the accurate LTE timing and set a DL offset, so the tx will be ahead of the real LTE timing to compensate the fiber delay, is this right?
And even with the at_ee_pi0_err the captured pi is corrent , just not within the window. I can still use the pi capture to estimate the fiber len. Is my view correct?
