Optional mnemonics
Some command systems permit certain mnemonics to be inserted into the
header or omitted. These mnemonics are marked by square brackets in the
description. The instrument must recognize the long command to comply with the
SCPI standard. Some commands are considerably shortened by these optional
mnemonics.
Example:
Definition:
INITiate[:IMMediate]
Command:
INIT:IMM
is equivalent to
INIT
Parameters
Parameters must be separated from the header by a "white space". If several
parameters are specified in a command, they are separated by a comma (,).
For a description of the parameter types, refer to

Parameters
A vertical stroke in parameter definitions indicates alternative possibilities in the sense of
"or". The effect of the command differs, depending on which parameter is used.
