A colon (:) always separates one command from the next lower level
command as shown below:
ROUTe:SCAN:MODE VOLT
Colons separate the root command from the second-level command
( ROUTe:SCAN
). The parameters of a command are separated from the command by

a blank space.

Command keywords can be entered in their full form, as shown above, or
can be entered in their short form. In this manual, the entry required in
short form commands is always capitalized. The short form is generally
used for examples in this manual.
Implied commands are those which appear in square brackets ([ ]) in the
command syntax. (Note that the brackets are not part of the command and
are not sent to the instrument.) Suppose you send a second level command
but do not send the preceding implied command. In this case, the
instrument assumes you intend to use the implied command and it responds
as if you had sent it. Examine this excerpt from the
shown below:
