The individual alignments may be:
— Coupled (default) - when they are in the same state, or
— UnCoupled - when at least one of them is in a different state than the other
ones
— Executed on demand, all of them, using the Align All Now
softkey.
Each of the individual alignments:
— could be in one of three states:
— Off - the alignment is not applied and is not updated automatically
— Auto (default) - the alignment will be updated over time and
temperature as needed, no user interaction required
— Hold - the unit holds the alignment values from the last
alignment-execution and does not execute another alignment
automatically
— can be updated on demand using the corresponding Align Now
soft-key.
Refer to “Individual Alignments” on page 184.
—The All Alignment
soft-key has the following functionality:
— when the individual alignments are Coupled, the state of all of them
can be changed simultaneously using the All Alignment
soft-key
sub-menus
— when the individual alignments are UnCoupled, they will be coupled
when using the All Alignment
soft-key sub-menus and their state
will be simultaneously changed accordingly

IMPORTANT! It is recommended that you use Align All Now, because it
includes the individual alignment InstAlign Amptd Align Now
, as well as,
Burst Align Now
, and ChanEQ Align Now. But, if you would prefer to have
manual control over the individual alignments, then refer to the SA
Individual Alignment Control setting in “Preferences” on page 637, in
Chapter 29 System Settings.
The notification AMPTD? displayed on screen means the InstAlign amplitude alignment or
channel equalization is stale (if its state is Hold) and requires an update or it is in the OFF state.
This situation does not occur when the respective alignment is in the Auto state. To clear this
notification, press the
Align All Now softkey.
