Query
A query is a simple or compound command
followed by a question mark (?). A parameter
(data) is returned.
Example
CONFigure:RANGe?
Command
Forms
Commands and queries have two different forms, long and
short. The command syntax is written with the short form of
the command in capitals and the remainder (long form) in
lower case.
The commands can be written either in capitals or lower-case,
just so long as the short or long forms are complete. An
incomplete command will not be recognized.
Below are examples of correctly written commands.
Long form
CONFigure:DIODe
CONFIGURE:DIODE
Configure:diode
Short form
CONF:DIOD
conf:diod
Square
Brackets
Commands that contain square brackets indicate that the
contents are optional. The function of the command is the
same with or without the square bracketed items, as shown
below. For example, for the query:
[SENSe:]UNIT?
Both SENSe:UNIT? and UNIT? are valid forms.
