Overview
All Alignment or Align All Now corrects for receiver drift over temperature and
time. SA measurement applications monitor changes in internal temperature
and the time since last alignment update and trigger the need for a new
update when the alignment becomes stale. The alignment is deemed stale
after a significant change in temperature or a significant time elapsed from the
last update. The temperature change and time duration necessary to trigger an
alignment update is predetermined in the factory. Until the update is
performed, annotation indicating "questionable amplitude" is displayed
