Implied or optional keywords are those which appear in square brackets ([ ])
in the command syntax. The brackets are not part of the command, and are
not sent to the AFG. Suppose you send the following command:
ARM:COUN 100
In this case, the AFG responds as if you had executed the command as:
ARM:STARt:LAYer1:COUN 100
The following information contains explanations and examples of the
parameter types found in this chapter.
