AD9371 Tx and Rx LOs not locked

Thread Summary

The user inquired about adjusting both Tx and Rx LOs to ensure a constant phase difference. The final answer confirmed that the same internal LO cannot be used for both, and external calibration is necessary to align the phases. The user noted they are not using an external reference clock.

Hi all,

I want to adjust both LOs (Tx and Rx) at the same time and guarantee that the LOs are phase locked (or at least the phase difference between the two is constant). Is there any option to control the Tx and Rx to use either the same LO or the same reference for the LO?? But I assumed that Tx LO and the ORx LO internally phase locked ??

Thank you
