Optional Key Word

Some command systems permit certain key words to be optionally inserted into the
header or omitted. These key words are marked in the description by square brackets. The
instrument must recognize the full command length for compatibility with the SCPI
standard. Some commands can be considerably shortened by omitting optional key words.
Example

This command enables the antialiasing filter to be inserted into the signal path before it is
processed by SENSe subsystem. The following command has the same effect:
