Implied (Optional)
Keywords
Implied or optional keywords are those which appear in square brackets
([ ]). The brackets are not part of the command syntax and must not be sent
to the digitizer. Consider the syntax ARM[:STARt]COUNt. Suppose you
send the following command:
ARM:COUN 100
In this case, the digitizer responds as if you had executed the command as:
ARM:STAR:COUN 100
Variable Command
Syntax
Some commands will have what appears to be a variable syntax. For
example:
OUTPut:ECLTrg<
n
>[:STATe] <
mode
>
In this command, <n > is replaced by a number. No space is left between the
keyword (ECLTrg) and the number because the number is part of the
keyword.
