GPIB Command Structure
To enter commands or queries you must use either the full word for the
command, or the three- or four-letter shortcut. Commands are not
case-sensitive, however spelling errors will cancel the command or query.
The command or query can be written using only shortcuts, only full
words, or a combination of both.
Other command syntax elements are:
³
The comma, which is used to separate values in a command or query.
³
The semi-colon, which is used to separate commands or queries,
when you send more than one at a time.
Note: It is recommended that you retrieve the response immediately after
each query.
