Has the frequency drift of the VCO/PLL in AD9361 been measured with respect to time or temperature?
We do not have any data of VCO drift with temperature/Time.
The PLL LUT's are tested across temperature and ensured that they don't unlock across temperature.
If you are looking for frequency drift , it mainly depends on reference . DCXO tune feature can be used if using a DCXO.
