Hello we are encountering locking issues at hotter and colder temperatures when using a full assist calibration done at 23C
It is bizarre because we can see the output become locked again on the spectrum analyzer when moving the temperature, and the output can be locked 1MHz steps away from the unlocked output
We can't quite figure out why this behavior is like this, but we are seeing improved results at cold/room when we do the full assist calibration at -40C (however it gets poor results at hot)
